"anybody have any experience on jet ski engines ?
a buddy of mine has a yamaha xlt1200 2004 seized on saturday so we stripped it today and one piston and barrel is damaged. now i can buy a top end rebuild kit inc pistons rings bearings, gaskets etc. and i can get the cylinder bored out and a cast sleave in.
question is, should you realy have liners put in all three cylinders or will it be ok to just sleave one and just replace pistons in others.
what would you do ????

If you only replace one liner

If you only replace one liner and can still use 3 of the same dia pistons you are good to go. I wouldn't go for a standard in one hole and 30 over on the other 2.
