slinger Group: Members Posts: 182 Joined: June 2008 Posted: Oct. 24 2008,19:56 I've been abit quite of late two reasons fooking credit crunch and having to let people go not nice to do that . But to the more up beat stuff I've been building and still am a bit of an odd ball. Well it's a 125 4HW frame 3XV swinging arm (sorry Jools for not getting back to ya). Modified Laverda forks and yokes, RS rare shock and a ypvs 350 engine which I hope to put some Trinity banshee kit on. Just started making the exhausts and there is a lot more to them than just getting a slip roller and rolling some cones . Well heres some pic's so fare. Glyn Back to top

I've got some 38mm flat slide carbs at last which have got a power valve on them how dose that work? Looks simple pipe from bowl feeding a jet I take it that it's just preasure loss through the card.

martin77 martin77 Group: Members Posts: 453 Joined: Sep. 2003 Posted: Oct. 24 2008,22:31 Powervalve? do you mean powerjet? if so, yes it's just a feed from the bottom of the float bowl to the top of the bellmouth which supplies fuel when the pressure is low enough to suck it up. Simple really... Back to top

Warwickb Group: Members Posts: 1911 Joined: Sep. 2003 Posted: Oct. 25 2008,11:59 Looks like a lot of fun, Glyn . A mate of mine was looking at putting a 350 valve lump in a 3XV chassis, but reckoned it looked like it wouldn't go in. Have you had to take anything off the rear end of the motor at all? Or is it just a case of careful shoehorning? If it ends up anything like Martins NSR-D350 it'll be larks-a-plenty to ride Do those carbs' powerjets have electronic solenoid control  or are the more straightforward 'always on' type?   If you'll be keeping a kickstart a 3XV one will fit nicely - and should clear the peg if that's a problem with the RD one. Keep us all posted, OK? -------------- A garage overflowing with old stinkers... Back to top

Keep us all posted, OK? Lol hi Warwick they are the simple ones that are on but to good to miss out on at Staford, couple of bits missing but easy to get hold of £60 I was happy . As for the engine at the mo it's not been chopped but it is as far back as poss. I know what your mate is saying because when I pull the forks down to there stops then the front wheel is close, Thats why I ended up making the exhaust I know it's a bit of a tight turn from the barrels but thats the only way I could get it in. If not then the swinging arm pivit point will have to go back by 30mm. So I''ll have to wait and see if it works on the track. Back to top

Simple is a good thing in my book, Glyn.   You can always blank off the powerjets and just set them up on the main too if balancing main and PJ adjutsment is a hassle for initial set-up. Good luck with it.  Looks like a great project to me. -------------- A garage overflowing with old stinkers... Back to top

No point having big carbs if the reeds are stopping them from flowing properly. Though even the 2MA reeds don't have the area to match 38mm carbs.... not to put you off or anything.... Back to top

I've got some Stan Stevens reeds and blocks from gaybay so was going to use them but if tz/ 2ma 3ma are better then your the guy's who are in the know . Once I've got the exhaust finished then I'll give you a shout Martin cheers for that.   Back to top

martin77 martin77 Group: Members Posts: 453 Joined: Sep. 2003 Posted: Oct. 26 2008,20:12 The TZ350's were piston ported and the TZ250 never had reeds until '85 (by which time they were crankcase reeds)..... TZ 750 blocks used to be the choice in LC's, but in fact they're basically the same as stock YPVS ones. Stan's blocks will do for the time being though...(don't get 3MA blocks... they're much too wide) Back to top

slinger Group: Members Posts: 182 Joined: June 2008 Posted: Oct. 26 2008,21:14 Martin just a quick question is it best for you to work your magic before I get it rebored or after? Back to top

Warwickb Group: Members Posts: 1911 Joined: Sep. 2003 Posted: Oct. 26 2008,21:54 So are the 2MA ones are bigger than the TZ ones, then, Martin? I'd alsways assumed the TZ ones were bigger (750, obviously)? -------------- A garage overflowing with old stinkers... Back to top

martin77 martin77 Group: Members Posts: 453 Joined: Sep. 2003 Posted: Oct. 26 2008,22:57 YPVS reed blocks are the same size as TZ750's (as I said above)...so yeah, 2MA blocks have more area, that's why I use 'em Glyn, it doesn't really matter, but I'd prefer to do porting after a rebore....

slinger Group: Members Posts: 182 Joined: June 2008 Posted: Oct. 28 2008,23:17 Well finished the pipes tonight   and I'm proper happy how they've turned out. Learnt so much doing them but well worth it once you get your head around rolling cones. Back to top

jools Group: Members Posts: 1221 Joined: Oct. 2005 Posted: Oct. 29 2008,04:06 Great work Glyn and is going to turn out a nice bike. My only comment, and don't take this as criticism, is that the header/diffuser looks like it may rob you of power - the angles of the pipe at the exhaust port and into the centre section are a bit stepped. The rest is spot on - did you weld them up ? nice job wish i had the gear & talent to have a go ! -------------- "The only thing worse than being talked about is not being talked about...." oscar Wilde Back to top

martin77 martin77 Group: Members Posts: 453 Joined: Sep. 2003 Posted: Oct. 29 2008,12:47 For a first set of pipes they're excellent... well done by the way, I should say if you're going to run 2MA reed blocks, then you also need some 6mm reed spacers to allow them to fit.... Back to top

Mr stinkwheels Group: Members Posts: 206 Joined: May 2006 Posted: Oct. 29 2008,15:12 Nice job, the pipes look sweet. I fitted a 350 YPVS motor into a 2MA frame, and used Swarbrick yammagamma pipes, in kit form, and welded to suit. One thing i did find was, because the motor is rubber mounted, it moves about a bit, especially under acceleration, and the pipes needed to be rubber mounted too, to stop the metal from cracking. Hope this helps. Back to top

Cheers Jools no problem with constructive criticism like the air filters you put me right on But you are right and I did know that the turns are abit sharp. It was the only way to get the engine in with out the front wheel rubbing when I compressed the forks up to the stops. But I reckon like most things with tuning these are stage one of many pipes I'll be making to get it right. I did weld them and learnt so much from doing them. More than happy for anyone to point me in the right direction and give positive criticism Glyn Back to top

jools Group: Members Posts: 1221 Joined: Oct. 2005 Posted: Oct. 29 2008,21:42 Maybe you could look at crossing over the headers. Probably to little space again though. Or maybe reverse the cylinders, carbs facing forward ? Not sure how easy that is on a YPVS though How does the weight balance front to rear seem ? The motor is very heavy compared to the 125 lump so you might want to check the front end isn't loaded up too much.

slinger Group: Members Posts: 182 Joined: June 2008 Posted: Nov. 07 2008,18:06 I'm like a dog with two dicks   Fairing turned up today missus phoned me up so I suddenly had a call out well thats what I told the customer I know the engine isn't in there, but it fits a treat with only a couple of easy brackets to make. But Will have some chopping to do for the exhausts but a small price to pay for beauty   Back to top

Mr stinkwheels Group: Members Posts: 206 Joined: May 2006 Posted: Nov. 07 2008,18:55 Thats looking good. Is that a Milling machine i see on the bench? I could realy do with one of those, where did you get it and how much? Question number 2, why have you got a corkscrew hung on the garage wall?

Cheers Stinky Yes it is a small milling machine with collets and cutters I paid £480  it's so handy and this bike would not have happened with out it I'll put the link up later where I got it from. Got a small lathe of gaybay proper usefull. Beer bottle opener got my beer fridge in there. Like my 250 red white and black. Back to top

slinger Group: Members Posts: 182 Joined: June 2008 Posted: Nov. 19 2008,22:50 Well I know your all not sleeping waiting to see what happens next . Engine in and the rad as well and it all fits just waiting for the crank to come back from CJ Engineering then it's build time Back to top

slinger Group: Members Posts: 182 Joined: June 2008 Posted: Feb. 02 2009,18:52 Well she started up over the weekend and even if I say so myself it sounds lush Had a few problems with wiring up the Zeeltronic nothing to do with the zeeltronic it was all at my end, that's what happens when it's all secondhand I guess   Ported the barrels and did the squish along with a good old blueprint of the engine. So off to the dyno when I get the chance. Back to top

Warwickb Group: Members Posts: 1911 Joined: Sep. 2003 Posted: Feb. 02 2009,19:51 Excellent! It's great to see innovation like that, Glyn. Will you be bringing it up to Anglesey? Looking forward to seeing it in the flesh -------------- A garage overflowing with old stinkers... Back to top

slinger Group: Members Posts: 182 Joined: June 2008 Posted: Feb. 06 2009,14:23 Well it's finished ok I've got the breaks to bleed and get it dyno'd but a part from that it's done ya hoo . Back to top

Andy Bush Group: Members Posts: 128 Joined: Oct. 2005 Posted: Feb. 06 2009,20:02 looks fantastic......and should be a peach out on track.. i'd have thought the rad might prove a little small for track action, but at least ya digi temp gauge is going to keep ya well informed ! credit to ya..

Malc Group: Members Posts: 29 Joined: Feb. 2009 Posted: Feb. 21 2009,20:32 Hi Slinger, A great thread overall, with some really innovative stuff going on in here. My initial though was you'd dropped a clanger with the paintjob, but seeing it decaled and livered, its pretty gorgeous. Be interested to see the final dyno results to see how your spannies have turned out too. Cheers! Back to top
