SX/SXi/SXi Pro 1998 kawasaki 750 xi sport

[rustybarnard440]

I just bought a 1998 kawasaki 750 xi sport and I did a compression test to it and the PTO side has 120PSI and the Mag side has 0 PSI. I took the top end apart today and found the mag side piston baddddly scored and stuck both rings. It looks like its been rebuilt not too long ago as none of the gasket were stuck and there were 0.50mm oversize pistons already in it. Its going to need boring oversize again as its scored pretty bad. Anything i should check or look over as i'm rebuilding this unit. Anythink these kawasaki 750 twin carbed engines are bad for? This is my first kawasaki. always owned seadoo's

Thanks For the help

Compared to a Seadoo there is fewer parts to replace. You have the typical owner induced piston seizure, usually caused by last years gas on a cool day. Make sure to clean the carbs and enrich the fuel mixture.

This may have been caused by the crank case drain, they are probably the #1 failure on these ski's. Replace it with a block off plate and while you are in your rebuild anyway, replace your crank seals.
