Looking at buying 3XV2

[teezer250]

Bulldogboy,
This is suitable for your needs,I put it in my 2 1KT tanks last winter and recently in my recently acquired suzuki burgman 400:

I always drained the carbs over winter to prevent gumming of the passageways.

Thanks teezer ill take a look.When you say "drained" ( past tense) does that mean you used to drain the carbs, but now ,with this additive you dont have to?

[Steveog]

Hope you get your 3XV back together without any issues Steve.
You need a good year where you just ride the bike, and the only maintenance is changing out your worn race tires throughout the year

Thanks, Randy. So let it be done.

I added ethomix to what petrol remained in the tank (about 5-6 litres) then run the engine to get the mixture into the carbs.
I then drained the carbs with the drain screw on the bottom of the float bowls,then put this back in the tank.

I have always drained the carbs for the last 16 years.

For winter i have been emptying the tank with a vaccum pump, then running the bike dry, but as you say i should really be draining the float bowls. Another member jamie tzr250r was using race fuel, sunoco optima i think ethonol free, was going to get some of that, run it through the carbs leave it in there ,then just drain the tank.

Took the Nissin/Triumph calipers off because I finally got my hands on a set of TZ Nissins

Looks real nice

Bike started losing fire in the lower cylinder at idle, and I pulled the carb to see if I could find anything out of the ordinary....and found nothing.
So, since I had a RGV project I was working on the TZR sat.......until today.
Got it up on the table for another look.
One thing I noticed which I need to find info on is one of the ignition pickups looks much further away than the other....?




Too much gap can be a problem on the RZV500R, wondered if it could be a problem on the TZR too?

The pick-up plates have kind of locating 'tangs' on the back of the screw holes to help them locate correctly, but you could loosen the screws and see if there's a little wriggle room to even them out? The first pic looks better. Think I've measured the gap at around .7 - .8mm in the past.

I've got the same lower cylinder issue with my 3XV1. It's driving me crazy trying to figure it out. The carbies have been on and off so many times.

[busa1300]

I pulled the pickup off and saw that the bracket was not at a 90 degree angle. So I bent it to 90 and the pickup has the right gap now.
Sadly that didn't solve the problem.
New needle and seat with new base gasket, fully cleaned in the sonic.
New plugs.
Bike fired right up ok, but as it idled the lower cylinder started to quit firing. If I gave it throttle it would fire back up on both cylinders.
And then I heard a bit of tick or almost like gear teeth clashing a few times...

So I shut it down.
Took it off the table.

I have most the parts I need to do a 100% rebuild. Just not the patience at the moment. I had just previously rebuilt the rear cylinder of my RZV after a melt down from carb leaning out because of rust from gas tank.
Have started to lose any interest in 2 strokes all together.... The parts searching really drags things out, as well as the cost anymore.

I'll get to it at some point, but I needed a very simple project to get myself back into rebuilding strokers.

So I bought the most basic and unruly bike I could find.

1973 TS400, with a TM400 top end and some sticky road tires.

If I can't get this one done, it might as well be lights out in the garage.

Reads thread......Google specs of tm400 

Very nice plan you have there.
Can't wait for you to show some progress in a thread somewhere   

I have looked at hopping up the performance of the ts125erz in my stable, but nothing jumps out. I dont think many options are about. Possible an air-cooled rm?   

For now it's just a nice bike to  cruise the country lanes on at about 45mph. Any faster and it's being flogged for little return.....I have the 1kt for that particular task

Do you think this could have been averted by a CHT and/or EGT monitor? Having four cylinders means more expense, but you may like to consider something like this (https://www.mglavionics.co.za/Infinitec/Manuals/Vega%20TC-4.pdf) or this (https://www.mglavionics.co.za/Infinitec/Manuals/Vega%20TP-3.pdf) which both allow monitoring of four temperature channels simultaneously.

That TS400 looks like a great 'vintage supermotard' project!  Please let us know how it goes by starting a project topic in the Other Bikes section.

After untold months of searching for some TZ wheels and rotors for my 3XV2,  I managed to win a couple auctions in Japan.
Date code verified the wheel is from a 4DP TZ250 (3.75x17) as is the set of Brembo floating cast iron rotors. So a basic direct bolt on. Still searching for a 4DP rear wheel (either 5.25 or 5.5 depending on year) This will let me use a better choice of tires when the time comes to get it back on the road/track.
Yea....definitely overkill...

The Yen is drastically down compared to the $ which made the purchase possible with my cheap ass...









And the TM/TS400 is moving along pretty slow, but progress none the less.

Nice score Are those discs spot welded?

That TS is gonna be wild..
