After buying my SP with the RS motor a few months back myself and the seller had to come to some arrangement to sort out the problem. So today a soultion was found. He had been put on to an ex race bike in Japan before christmas and asked if I was interested. I looked at a few dodgy photos and we agreed on the price assuming it had the good parts fitted I would take the bike.
He came back from Japan today and the bike will be in the next container. It has been sitting for a while so the motor will need doing but as I am already building up the other SP motor anyway that will be used. It has what looks like Sugo pipes as they are the same as the ones I have here, Sugo 70 CDI, 36mm carbs with the covers and I assume Sugo internals but who knows, no airbox, TZ clock bracket, the fairing is missing just the seat unit is there. The history is unknown but perhaps its an F3 bike.
So now I have a few months to finish my RGV and get rid of it to make space.
That sounds like a good bike you have found . Good luck .
Lets hope the same bike turns up ;D
Any spy pics ?
I will try and get some the next time I speak to him but it needs a good wash
You got to many bike now ;D Wouldnt be the TZ way better than the TZR to track it?
Yes but I want to answer the question of which is better once and for all, the TZ or the TZR, its for the forums benefit honest ;D Anyway I already have way too many bikes so what does one more matter :)
I agree. ;D
What's one more bike !
It must have a Sugo or similar loom also because the CDI is mounted under the dash like the TZ
May I ask how much it will cost once it has landed ?
I believe that these ex race bikes deserve a new lease on life , even if they only end up in a museum is better than them rotting away .
You can ;D
I dont like having to many bikes. its hard to maintain and cost hole in my pocket. ;D
Looking more and more like an SPR, the CDI is 3XV-7K and according to the Gecko list thats the SPR item 8)
I was working out the price on all the Kit parts on this thing and its up over $2000 using Geckos price list. As long as all the parts are still good I will be in good shape. I will use one of the spare TZ fairings on it as well if it fits, I have three spare fairings.
The container is being packed right now and leaving Japan next week so I should have my hands on the bike mid March 8). My RGV is getting the door to accomodate it and as it has the kiss of death on it anyway I will be glad to see it gone.

feel the same way about my prilla
cost me tonnes, basically i was polishing sh1t
handles great but the engine is exactly like you say, after all this money im scared to ride it
you bought a TZ and a TZR race bike to see which was better, just post me your TZ when you're done.
I can't get over the crap build quality of the RGV, what a pile of rubbish.
Australia Post will only let you send objects under 1100mm long and under 20kgs Paul so I will just have to keep it

scott, the 3xv is the unrivalled winner, that is a fact. erm... please post me the TZ
Getting some fairings as a bonus as well so now I have a complete bike. Mind you I presume they will be street fairings so I may have to sell them anyway.
Hi Pat , I will be looking for track fairings mid year if you know anyone down under or would I have to import some ?
There is a company just a few streets away from me Neal that do fibre glass fairings. I asked them about a set for the 3MA but they only had the mould for one model TZR and I cant remember which one but I have a feeling it was the 3XV, the details are below.
I plan on fitting a spare set of 4DP ones to my bike anyway providing they line up.
Handcraft Fibreglass
19 Prince William Drv, Seven Hills, NSW 2147

Pat,
I think you are correct - my first TZR came with one from those guys and I'm sure it was 3XV.
TZ127 told me he had some moulds when he popped over the pit garage on Friday. Just so busy I never had time to go back over to see him.......
My bike lands on Friday so customs might release it by the following Friday and I will see what arrives. I will pop over to see those guys in the next few days and confirm the fairing situation.
I finally picked the bike up this morning just have to go back for the fairings etc. This bike is an SPR and has the oval carbs still fitted. I haven't had a chance to go through it fully yet and note what parts it has but here are a few pictures.
First job is to strip the forks and get the legs re chromed, they are not too bad but still no good. Then strip the motor and crank and see if its usable.
It also gave me a chance to use my new trailer that I only finished building yesterday, I still need to set it up but I'm happy for now.
There is a scrutineering sticker on the frame saying SSC Sugo Sports Club technical inspection 8).
Looks like it has sugo pipes as well, probably sugo everything! Easiest way to get everything in one go and lots of spares!
So jealous! :P
Looking forward to see the progress on this bike 8)
I wonder why the sticker is written in English and not Japanese.
3XV-7K cdi
107233 chassis no
3XV 75 loom
3XV-50 barrels
I think someone made off with the forks from the bike because looking at the fork legs this bike has been sitting for a while but the tyres are not even blue, they look like 2-3 months since last used and the overall condition is not that of the fork legs. Anyway it doesn't matter I am off tomorrow to pick up the rest of the parts.
Can you blow up that green sticker ? Any chance somebody can make a replica ?
Actually it says Sugo Sports Club, I edited the earlier post and the pink sticker is one as well. I can get them scanned off the frame locally which is what I was planning.
Trailer and bike both look great to me! 8)
Ditto what Wozza said Pat.
You are going to have a lot of fun in the coming months one way or another.......... ;)
I just need to make sure I hide to receipts for the parts ;D
The fairings that were with the bike were half 3XV and half 3MA3 panels so if someone needs two side panels and the centre triangle for a silky white 3MA-3 let me know. I also scored some other parts today, a second set of Ox Racing rearsets, spare SPR rad, TZ style plastic tray for around the carbs and catch bottles, spare sprocket carrier and four rear and one front sprocket.
See you tomorrow Jools
I couldn't help myself last night and had to have a look inside the motor. The crank is perfect and no signs of moisture anywhere. I am going to fit new seals and reuse as is. The barrels are good also, the cross hatching is still there and the plating is sound. It had SP pistons fitted so they will be replaced with TZ ones and kept for reuse as they are perfect. The only problem I had was with the head studs, the SPR uses bolts like the TZ instead of studs and nuts on top like the other 3XV models. This also means it suffers from the same problems as the TZ with the studs shearing off. I got them all out except one that sheared with no pressure applied. Normally in this situation I just build up the remaining bolt piece with weld and the heat transfer takes care of the rest just grab with a vice grips and out it comes, not this bolt. I couldn't even drill it so after two hours I went home :'( This morning I had another go armed with some kick ass drill bits and got it drilled >:D.
So thats why I didn't see ya at the track yesterday ;D ;D
I meant to see if you wanted a spare pass i had but I forgot with all the busy to and fro ing.
Thanks again for the help Saturday. Got some dyno time booked with the 2MA F3 to set it up or identify the problem.
The 3XV was singing, especially after i dropped the needles a clip. i think the pilots are a size too rich as well.
May stick her on the dyno just for a test run while I'm there as I'll be interested to see what she puts out now.
What dyno are you going to use?. I just got back from the track now and we were lucky with the rain until 2.30pm when it came down lightly everyone was on slicks which was ok because it wasn't too wet but they had the yellow flags out and the muppets were doing about 20kph around the track. Result all the heat went out of the tyres, cold slicks and wet track >:(
Ah thats right your track day - sorry I forgot about that :o
Its a guy I know that has a dyno in his shed, but he is a bit cagey about what he does with it and who he will let use it !
Mad professor type that dummy spits easily...........I'm lucky he's still talking to me, but then I never hassled him and use to pop around for social visits.
you should install one in your workshop - he made his own not sure which software he uses, its not dynojet.
Secret tuning shop, I like it. I can't really take up any more space with bike related stuff or I won't be able to do any work in here ;D. Mind you I did build the rolling road that I could adapt.
I got the bottom end of the motor back together now with new crank seals and gaskets. I need to get new O rings for the head and make sure that the base gaskets are the same as the other models as I have spares and TZ O rings there. I need new head studs for sure. I stripped the forks and will drop them off for rechroming tomorrow. I had to make a few more tools for the job but that's ok.
I have new TZ pistons there also so all is looking good. I also found a buyer for the 3MA panels so they are gone also I just hope the TZ stuff fits without too much hammering .

i can probably get the plans and give you hand ;) you only need a small amount of space.
True but as anyone that's been to my shop will tell you Jools I have a lot of small items and together they take up a lot of space. I got a 20ft container thinking yea that's the answer, now I cant get in the door :D. Its going to be some deceased estate sale here when the time comes 8)
The top end parts I need are the same part numbers as the 4DP which is handy as I bought a few spares the last time round. I just need to order some head studs.
Does anyone know where I can get a digital water temp guage for the TZ. One that plugs into the top of the rad is what I want. I was thinking of trying a go kart shop and see what they have.
I'm tryimg to think - the one I use on my 2ma, used to adorn my 3XV and is a YEC item.
They come up on Yahoo Japan from time to time.
http://www.ebay.com.au/itm/Go-Kart-Italian-Digital-Water-Temperature-Gauge-H2O-Temp-Unit-0-150-Degrees-/370622961836?pt=AU_Go_Kart_Parts_Accessories&hash=item564ad998ac
this might be what you need
Not much left of it now.
I also scored these along with some other tasty parts. I grabbed them regardless but now looking at the picture of the 95 SPR Sugo parts list they look exactly like the ones in the picture.
That's good Jools I found the exact same one in Homebush online about two hours ago, $5 cheaper too so I might drive east instead of west ;D .
http://www.karts.com.au/index.php?main_page=product_info&cPath=345&products_id=1304
I bought the guage yesterday and had to make up an adaptor to go between the Rad and the probe. I bought an M16 x 1.5 pitch bolt and drilled it out and tapped it 1/8 bsp for the probe then cut it back as short as I could so the probe went through as far as possible . Looks good all fitted up and at a cost of $77 plus the tap its a lot chaeper than the one left in Japan for $375 :)
To strip my forks to get them rechromed I had to take the fork tube out of the lower caliper/ axle part. To do this I applied some heat and used an Allen key to remove the grub screw then clamped the lower part in the vice and used a vice grip clamp, not a normanl vice grips a large grab type used for welding with a rag to protect the tube. Then applied some more heat and it unscrewed really easily without very much heat at all applied.
Got my fork legs back today and just waiting on the seals to put them back together and on the bike. This week the top end parts should arrive and I think I might just check the coolant hoses for blockages before I hook them up ;). I need a new chain too and when I get the wheels on I will try to fit the bodywork.
Front end is all back together now after making all the tools to do the job on the forks, not an easy job on your own. Also the top end parts are here so over the weekend I will hammer the motor back in. I will need some tyres but for the time being these will do.
I might run this on 50/50 avgas/ unleaded, does anyone know the squish and head volume for this. At the moment the volume is for unleaded but I need to check the squish yet.
As I understand it the 7k CDi is designed for Unleaded, so you may not need to bother with avgas? Your heads look to be bigger than earlier SP heads too, and more like R heads in dome design? I don't know if that's stock for the SPR heads though as I've never seen any in the flesh.
The 3XV-60 heads are around the 9.78cc mark.
My spare TZ heads are marked up as 6.0cc but I'm not sure if this is correct........the squish is bugger all to I would have to watch the deck height on these.

My volume was 10cc exactly the same as the SP. I will compare the SP and SPR heads tomorrow.

Cant remember the vol off hand, but something around 8-9cc or so I think? As I said, they look to be a bit smaller (with a wider squish?) than the SPR - unless it's just the photographic effect?. The ruler might help there? Not sure what 93/94 SP heads are like?
91-92 sp heads are about 9.8cc measured with a flat perspex plate laid across the gasket face and a spark plug fitted.
Roughly 8.7cc fitted clearance volume to the bottom of the spark plug hole.
Dan
The SPR head is .45mm wider than the 92 SP head.
I got 12cc with the plug removed and filled to the top of the hole with my 92 SP head. I have to check the SPR again now
Looks to me that the SPR maybe has a narrower squish area overall? With a bigger volume dome than the early SP head from the pics? It's always hard to make things out clearly from pics though, so let us know how the measured volumes compare, won't you? It's really interesting stuff as I've only ever seen the early SP heads in the flesh.
Are the dome 'sides' straight or concave?
That second photo of mine is the SPR head - for some reason when I tried to post the 4th - the TZ head chamber - I kept getting an error message.
Here are the two for comparison, the TZ has the "top hat" style chamber similar to the unleaded 4TW with the copper inserts.

Motor back in now and some of the accessories hooked up. I have to repair one pipe as there is a dent in the side of it, should be an easy repair though and I might even give them a lick of paint depending on how much weight that adds ;D.
I offered up the TZ fairing and its a good bit off and will require a lot of messing with. The biggest problem would be a big section missing right in front of the lower carb. Any debris, water or anything at all has a clear run into the carb, I'm not liking that idea much.
The bike came with a belly pan only and Jools suggested it was a Sugo item. I have no reason to doubt that but has anyone got a set to confirm. Can I but a matching top piece anywhere? I am going to call over to the local guy and see what he has next week but it seems a waste to not use this one plus I don't want to spend money on a new set if I don't have to.
I can always fill in the section missing from the TZ set if it comes to it.
I did a quick search to see if I could locate the fairing I saw on Yahoo.jp but its not coming up.
I did see this though which isn't a bad price......
http://japamart.com/auctoold.php?url=http://page22.auctions.yahoo.co.jp/jp/auction/l108976186
I think that is for the front stand ?
Let me know how you go Pat as I will need some race fairings too . I may get some from SA but the customs clearing agents are reaming me at the moment with my parts in the container .
Not to thread jack ::)
Neal who in SA makes race fairings to fit the 3XV? I have been trying to locate some for a while now. Thanks
racebox
rather fit a 4DP on there, ill take a spare if you order.
From Racebox Paul?
Yes from Racebox , Gerhard has the 3xv moulds and should have a set of TZ moulds . Their fairings are decent IMO .
This is the cut out I'm talking about Neal. The TZ fairing goes right across the bottom of the rad on the 4DP but with the 99 fairings. This only goes half way across so the intake for the carb is in the direct line of fire from the wheel, it also does not come all the way up to the rad but that may be because it was designed for a TZ not a TZR.
That's a good price Jools, TZ look alike style.
I fired the bike up last night and she sounds good. I need to check the float levels as both carbs leaked a bit and I need a new o ring for one. She fired pretty much straight away even with the old plugs. I just wanted to do a heat cycle and make sure there were no leaks. There is a leak somewhere in the side of the rad but its so small I cant even see it. I got a spare anyway so I can just swop it out. My new temp guage doesn't work but hopefully it is just a dead battery that for some reason came already installed and must have just got drained.
I think that cut away is for a ram airbox on 2003+ TZ
I had a look at that add again Jools and its for the stand not the fairing ;D
;D ;D
sorry Pat
should have used the translate button ::)
I went around to see Handcraft Fibreglass on Monday. They do a set for the 3XV but when I looked at the mould it looked a lot bigger than the fairing on my SP. I took a measurement across the front from where the hand area is and sure enough its 150mm wider than the SP one. Not sure why because the mould was just an original fairing panel so somewhere along the line one model must have a wider fairing.
I was not that impressed with the product to be honest and for the same money I can get one out of Japan so I will just do that.
Also got my carbs sorted now so they hold fuel. The rad stopped leaking I think so perhaps it was just a bit of residual coolant that dripped.
That sounds like the one I had. It was altogether different and I think it is an earlier TZ model but its hard to be sure which one if it is.
I had to do a lot of cutting away around the footrest area and radiator to get it to fit.
I laso junked the standard front fairing mount and fitted a TZ style, which is probably what you will have to do with that 4TW fairing you offered up, but beware as the front frame mount is subtly different and all TZ brackets from 3YL up to 4TW differ from each other. Its a right royal pain. I ended up using a 4TW style but made my own side plates to mount to the 3XV frame.
Then you have to either have to fabricate a mounting system for TZ style top stays or modify the std 3XV top stay to fit. Onmce you have done thyat ypu also have to consider the side frame mounts & their positioning. on the RHS the old airbox captivated nuts arent far off but on the LHS I drilled the frame and fitted a Nutsert for the fitting.
Oh, yeah don't forget front tyre clearances. ::)
Its a great fun way to while away an evening ;D Worth it in the long run
I just purchased a fairing in Japan, it was going to be the same price as the one locally plus postage but the local one looked pretty bad to be honest. It will take them a month to get it made but that's ok.
Talk to Damian Turnbull this weekend - TZ127 - he mentioned that he can get them
Too late now the payment has been made.
I have 4 weeks to get the bike race ready because I am going to race it at the next round in the F2 class. I will be up against 600s and the like but the track is pretty tight for the next round so I should be ok. I am already entering the TZ so the second bike is only an extra $20 and that's cheap track time >:D.
After all my prep work including rebuilding the motor in my KR1 I wont get to race it at all because the class is combined with the 250GP class all the time and I am not parking the TZ to race the KR1.
I wont have my new fairing for the SPR in time so I will just bodge the spare TZ one for now and get out there. I also need to fit the EGT, get some tyres before the event this time, a chain, pads and perhaps do some test runs up the road at night ;) No idea what the suspension settings are at the moment so they need to be addressed too.
We are ready to go now. The fairing actually fits well but it is under a bit of strain here and there. The front cut out I just taped up so the I didn't have the front carb in the direct open airflow. I had to cut a piece out of the right side to let the kick start pass and made a top brace like the TZ out of stainless. This fairing only has to last one race meeting then the new one will be fitted.
I fitted the carb scoop surround things to hopefully stabilise the air around the carbs and locked wired her all up. New chain fitted and a set of slicks Bridgestone ordered before the race this time.
The colour is shocking but at least I'm going to stand out from the crowd ;D
Very Pretty................ ::)
Still, as you say it will keep the scrutineers disctracted. Don't forget to lock the rear caliper bolts - new antagonism for 2013 ;D
For some reason MA have decided that modern bikes only need the fronts locked wired while everyone else needs front and rear done.
Tyical - no consistency !
My fairings arrived on Friday morning from Japan. 2 days in the post Japan to Australia, unreal. It takes longer than that to post something 100km up the road. Anyway they looked good but I had to o a bit of messing about to fit them due to the position of the Sugo CDI etc being in front and in the way. The belly pan is hard against the exhaust but I will just see how it goes, the Sugo pipes may be a bit fatter.
Got some new slicks fitted so I am ready for the weekend and hopefully the rain clears off by then or I will be raping the SP for its wheels.
Looking good Pat and seems a reasonably good fit.
Put some of that adhesive heat protector where the pipes are close as they will discolour and burn through - take it from my experience. I also lagged the pipe with some exhaust bandage from MCA in that area.
I think I have some left over heat proof tape somewhere
Man, that looks, really, reeeealy nice.
To performance strokers ready for the track.
Have a blast ;)
Yep pretty happy, its just a test session for the SPR as I have only ridden it around the car park so I don't even know if the jetting is anywhere close. Also up against six 600s in the class.
Well I had the SPR out yesterday for race day, only ran it around the carpark before this so it had no idea how the jetting would be or the suspension or gearing. The front end was too soft in practice/ qualifing and the carbs were a bit off and the bike was fluffy off the bottom but other than that it was perfect.
When I got to race it it just went better and better I wound up the front forks a bit and adjusted the carbs up and synced them up but I thnk the float height is wrong in the lower pot but while I was riding it it was ok just ilde or in the pits gave the problem.
As I got the hang of the bike I couldnt believe how well it went and in the last race I had passed a few diesels and had some clear air and actualy finished with a time 2.5 seconds faster than the TZ for the day :o I did have the usual bad starts on the TZ and when I changed the gearing for the last race I fried the clutch taking off so it was slipping for the race, traffic was also an issue. But that said the SPR is a great bike, it hooks up really well off the turns and for yesterdays track anyway the gearing was perfect. It an easier bike to ride because the power delivery is a bit nicer. And all this with the old plugs that came with the bike >:D
Next thing is to get the front forks set up and tune the carbs a bit, I am also going to dyno the TZ.
That sounds positive Pat , keen to see how the 2 graphs overlap between the bikes !
Hopefully I will have that info Friday Neal then its off to get the front end sorted. If I ran the SPR in the F3 class where it should be I was 6sec a lap quicker than the guy who won the class, but that's the down side of combined classes I suppose :(
Went to the dyno today and this is the printout. I'm pretty happy ;D
This is the overlap with the TZ. The big hole is at 9000 where the PVs open
You can certainly see why it is easier to ride than the TZ. Good stuff!
Dan
Wow!! Impressive power
I'm really happy with it and having ridden it I knew it would be a good result. That means the Sugo kit gives you 26hp extra on this model.

nothing biting today..........if you get my drift ;D
Oh ! Your TZ needs a rebuild cos it is under powered and the TZR is is over reading on the dyno cos they come from the factory with 45hp ? ;D
Yes yes Jools I got you now, still not getting one :)
I think I will buy myself a nice small car instead
SPR looks great in its new plastics 8). Power curve looks great too (the RGV boys would kill for a linear curve like that! :D). Revs very well and hangs onto the power nicely. Great stuff!
Did you decide on AVGAS or unleaded (or mix?) in the end?
Thanks for sharing :).
It's good to see that the 2 graphs are close , makes me wonder if the SPR gets ported more if you could close the gap or ruin the curve ?
Once again Pat , great to see the comparisons !
I ran 95 unleaded after checking the squish and left it at that. I am still running the old plugs, jets settings etc that the bike came with so obviously someone knew what they were doing in Japan. Each carb is slightly different internally from memory the tubes were different. Having ridden the two bikes back to back there is a big gap between both bikes right now. The TZ is fast when it gets wound up but that big dip is the problem and you lose a bit of exit speed where the SPR is just great and therefore faster. I have to fit the other top end and new pistons and then see how we go.
Looks like the 7K is indeed good for unleaded then. Good stuff.
Indeed. A sorted 3XV is a very effective bit of kit for a 20 year old road bike isn't it? 8). Great to see it's going so well for you :).
A surprise package for sure 8)

Went to the dyno today and this is the printout. I'm pretty happy ;D
Pat,
good to see you sticking it to those Pesky 600's at Wakefield Park yesterday. The bike sounded and was going very well. We left about 2.30 as the old fella was getting a bit tired. The last race we saw was the TZ race. The red diesel up front was going well but expired (as they do - too many moving parts ) just before the line and Harley managed to nick the win, Glenn Hindle on the RS finished next and then Steve Kairl on my old TZ.
I could see how fast that TZ is it pulled away/caught up from all the other bikes on the straights. I could tell Steve where he is losing out but that won't help me when I get out there ;D
Looking at your graph that little dip seems to be where the power jets shut off so I reckon its just a wee tweak down on the main and up on the powerjet.
Cheers Jools,
The SPR was humming yesterday again but up against 600s and 1000s its always going to be a hard ask, pissed a few off though around the outside. I messed up a premix in the morning and had slightly too much oil but it went well after it burned off. I have struggled a bit on both bikes with the start but have now settled on as soon as the lights go out letting the clutch out at 12,000 and that seems to work.
In the GP race I qaulifed too far down the grid as its been about 7 years since I was last at this track and then I broke my femur in two places and spent a week laying in a hospital bed so I was a bit reserved in the morning. I was getting the usual bad starts but agian if I launch at 12,000 its not too bad but if the revs drop below 9,000 its into the dead zone and it bogs. This is exactly what happened in the last race, I got the jump on the other TZ ahead of me on the grid as he got a bad start and got my nose in front but it bogged and he was gone and then I had to content with the tractors that had come past. I modified my riding style to drop an extra gear everywhere to keep the revs up so the bike never got below 10,000 and all was well. I had both bike within .1 of a second of each other with the TZ just in front at the end of the day.
Thanks for the speedo also.
The post man finally delivered my spare SPR motor yesterday from Japan. Looks good and should just need a freshen up with new seals and a few bearings and a set of TZ pistons. This motor will be on stand by when the other one lets go. It took me a while to find an SPR top end and they are not exactly cheap so when the whole complete motor popped up I grabbed it. It cost the same as two barrels almost.
Well I suppose it had to happen really, I didn't have to get the spanners out for any repairs at all during the season on either bike but that changed yesterday. I crossed the line in the first race when the SPR dropped a cylinder, the top one. I coasted back to the pits and pulled the plug out and there was water all over it, the O ring had let go. Luckily I had some new spares as the fact that the TZ and the SPR share the same O rings makes it a bit cheaper. I did a hasty repair having to stop mid way to race the TZ refitted the same plug and raced for the rest of the day without incident. Having said that first gear has had it and most times it wont engage so looks like I need to rebuild that also, Yahoo here I come 8)
Here's a video from Sunday in the second race on the SPR. You can hear the numerous missed gears going into first >:(.

Nice ride! How many laps was that?
6 laps 8)
Sounds awesome Pat! Looks to pull really strong and blast through the revs quickly too.
Have you tried lowering the needle a touch to stop it four stroking on part throttle? Just an observation!
Dan
I haven't touched this bike to fine tune anything since it came from Japan, it still has the same plugs fitted :-[
I pulled the top head off today and checked it was flat and it was, I also checked a new head for reference and it was the same. I checked them in the lathe with the dial guage. The o ring failed this time because it broke. I have bought 3XV o rings this time to see if there is any difference in the life span over the TZ items
I might get both heads machined just to make sure anyway.
might have been "old stock" Pat.
Might be but the package was fresh looking. Anyway she is back together now and getting prepped for the 9th of November.
Good luck Pat !
Going to need it racing all the late model 600s and 750s. At least I will only have one bike to look after that day and I might even get the front forks looked at beforehand to stiffen them up.
This is a nice bike do you have the same fly wheel setup as Neal ?
No I just have the Yamaha flywheel on mine, I'm not mates with Kenny like Neal is ;D
:o ;D
I am having another one made soon as the season is finished this year . If anyone wants one I can keep them updated .

Do you think the weight of a battery is less than the setup you have ?
Whats the cost Neal ?
I missed this - any photos ?
No prices available yet as I have not sent mine for measuring . This flywheel is light , the bike revs very quickly when you blip the throttle , much better than other skimmed flywheels I have had on other bikes before . I don't know if the bike performs better or worse with this set up as this is how I got it but from previous back to back dyno runs comparing skimmed flywheels it seemed like the skimmed unit offered more hp than a stock unit .

Do you think that was a works yamaha part ?
Sorry to side track Pats thread .
This part was on the Marlboro team bike that Robbie Petersen had from the team racing in Asia . Another gentleman told me they were the only guys that had those flywheels and he raced against those bikes in the day .
They may have been YEC parts
Raced the old girl yesterday and it went well. I raised the mains by 10 and in the morning it was ok but by the afternoon it was too rich and trying to foul the plugs. The track was super hot and slippery and every race had to be red flagged except for four races. The carnage over the weekend was unreal, we had 6 helicopters fly in and 27 medical pick ups on Sunday alone. By the end of Sunday I was the only bike left in my class and in one accident 8 bikes got taken out when a diesel blew up and dumped oil across the track on a blind crest corner, turn 8 at the creek for anyone that knows the track. We only got a race and a half in for the day.
The bike needs a front end tune and a motor refresh now for next year as I plan to run it all year in this series with the 125 and use the TZs in the other series, going to be an expensive year 8)
Heard it was a shocker there Rodger Green from up here got banged up pretty bad :(
Yep sure was
If the knob heads replying to Steve Kairls Facebook post were anything to go by you'd best steer well clear in future. Chest beating Neanderthals comes to mind !!
I seem to recall I did a St George event years ago and one class was full of nutter weekend warriors then. Lets hope they stay there............
Just read those posts Jools, a few hero riders there alright. I raced the St George series about 8 years ago when I could ride properly and found it to be a "safe" series so I don't know what went on last weekend. I think I might stick to the small bikes for their series.
