Yamaha tri-z 250 issue

[nd4speed]

Wow, $300 for a dealer to put in the wrong piston? Sorry to hear that.

Put in, no no, he sold me the wrong piston after I went there when I had the engine out of the trike.... I mean I came there he took measurements and sold me a 300$ piston. lol I guess I was to naive back then, so in the end its again an affordable lesson right.

At least I found the problem on my tri-z, and thats such a relief

Piston got in the mail today, hope i can mount it this weekend!! Then the final test, can't wait to feel the power ones again Keep y'all updated!!

When you haven't run it for a while, or if the carb bowl is empty, try blowing in the vent hose that runs up to the steering head from the tank. Doing this will fill the float bowl. Once you carb is properly adjusted this will reduce starting to just one or two kicks.

That is a pretty Yamaha!

At least you are on the right track. I hope this fixes your problem.

@Jamve, thanks!! Yeah very happy with this Tri-Z as these are becoming very hard to find these days here in The Netherlands. I guess I was just lucky to found one in this condition considering its totally stock and even has all the stickers it originally came out of the factory with

The Z starts now second kick when cold and first when its hot. Adjusted the carburetor.... now just dealing with the clogged silencer....have to, professionally, cut it open and replace all the wol and clean the damn thing. lol

Pretty sure this is keeping the weel from coming up in 2/3gear as when I removed the rear part of the silencer it felt more powerful already.

It wouldn't be a surprise, considering the bike has driven only one time a year during the carnival with the previous owner when he bought it from 1987 as old stock Yamaha. Probably never adjusted carb so might have spooged (runner rich) a lot. Ah well imho better rich then poor

that is a nice z!

The inside baffle can be removed without cutting silencer apart.it takes a little work but if you take a good thick screwdriver or pry bar and keep bending the core smaller and smaller it will finally come out the back end . i have taken alot of them out with just a little time
