yamaha tech question

[bill williams]

i just purchased a 1988 gp800 with a blown engine. ( the price right ) i tore it down and found number two rod broke a hole in the case below it and a piece of the cylinder broke off. my question is this. am i better to put a short block in it or rebuild what i have? crank appears to be in good condition. any advise?
thanks!!!

#1-Crank will have to be overhauled, new brgs at all position, as metal has probably been rolled in all the rollers/races.

2-I have a shop that does race car-tractor pull engines, so weld of block is trivial for them.

The rest is trivial work for you and local machine shop to fit new pistons.

Thanks!! I only wish my engine looked like yours

If you swap with us, don't repair the case - we need to do it.

Are you sure? I seen a 800 recently, definitely lees stuff on the 800, even more room to get at most whatever in the hull. You gots to see a 1100 or 1200 shoe-horned into a hull.
