Tri Z - Big Bore Kit....any around or can you sleeve it?

[Darius1502]

I was looking at some of my old ATV News newspaper and say an ad for a big bore Tri Z clynder which was 317cc!

Has anyone heard of a company that could do this today?

thanks...

Nope...but I'm scrounging parts off of an 85 YZ250 so I can put the powervalve setup on it(My Z). I've got a cylinder and head now, still need all the powervalve peices. The cyl is on the last bore so I'll probably get a LA sleeve for it. If I can get a big bore I will. If they do have one, I don't see any reason it couldn't work on a YTZ.
