    Weisco make 90mm (+2mm oversized) and 91 mm (+3mm oversized) pistons for the 98 XP-L. They have a catalog that you can download on their web site.

    Weisco' s are forged and they need to be set up with more cylinder clearance than the OEM cast pistons. It is also more critical to warm the motor up for a couple of minutes before nailing the throttle, but that's a good thing with any piston. Unless you are going to do some porting to the cylinder you are probably better off just getting new sleeves and going back with stock Sea-doo pistons.
