WTB SL750 Piston

[czsd1d]

I just got a 1995 SL750 and it has a cracked piston and I was wondering where a good place might be to get a new one at. Ive looked on ebay and there were only forged pistons on there and Im not looking to upgrade the motor right now. I would like to find a stock replacement if I could but I dont know where to get one. Any info would be greatly appreciated. Thanks.


Here are a few pics by the way.

Check out the Ebay stores for a WSM piston kit.

Be sure to check crank index with a crack like that.

I am new to working on jet ski's and exactly how can you check the crank index?

Also what are so good things to do to the jet ski to upgrade it from stock. Are there any upgrades that really need to be done to make it more reliable?

Dial indicator and a degree wheel.

Each piston should be exactly 120* apart for 3 cyls and 180* on 2.

High compresson heads, ported cyls, performance reeds and/or reed spacers, and peformance Flame Arrestors and aftermarket impeller.

CAUTION: any of these mods can require carb jetting changes.



Performance ride plate, intake grate, pump wedge, or long jet pump.

POSITIVELY upgrade the fuel system. New hoses and maybe the triple outlet fuel pump. Thoroughly clean the carbs and fuel shut off.
