After trawling everywhere for info and trying to identify an engine i acquired; thought i might ask for some pointers in a few things.
I'm haven't been a Two-Stroker since my first bike. A friend had a yamaha engine he wanted to sell so he could fund another build and I snapped at it. He got it from a breakers and was sold as is.
So far, he changed the clutch plates, added carb and new air filter, and replaced piston. He gave up on the engine after he couldnt find any manuals on it or identify it as anything other than a yamaha engine (He's not a yamaha rider).
