Tri Z big bore

[Tri Z]

I am wanting to "big bore" my 86 Tri Z. I need to know a good big bore kit, or if a yz250 kit would work???????????? I tried L.A. sleeve and they dont carry one for a Z. so i need to know a company

Thanx

I am not sure about this but way back in the day, many years ago I had heard that yamaha actually made a stroker kit for them. This may all be BS, but that is just what I had heard. That would be a sweet option if true. Even if it isnt I am sure crankworks could build you one.
