Pistons?

I need to do a topend rebuild on a 2005 SkiDoo 800 HO. Does anyone have any suggestions on the type of pistons to use (OEM, SPI, Wisco, etc). Thanks Jeff

OEM would be best fit.

Thanks RJ........The sled has 11,500 miles and has medium compression in both cylinders. Still runs but not at its peak, If you know what I mean!

I have alot of shop work to do now. I just bought 3 skidoos and a 4 place trailer that have been sitting for about 4 years. I love it when there is tinkering to do in the barn...THINK SNOW!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

OK so i tore down the sled and i have bigger problems then what I thought...lol. I have a pic of the piston I was just wondering if anyone know what caused this. The cylinder is junk...unrepairable....But the pic is the clutch side-exhaust port piston.

i went though mcb performance for my cylinders and pistons on my mxz. i had great service and the parts were great. they have dual ring piston that worked amazing. a lot of skidoo guys also rave about rktek.... but if you have had good luck with the oem then you can't really go wrong.

Isn't there a sleeve that can be removed and replaced? It should be a lot cheaper to re-sleeve it than to find a new cylinder.

I just did a crap load of research on this. There is no sleeve on the 04-07 800ho they are plated. I just ended up buying a re-manufactured cylinder. Wasn't to bad for $200 plus core!!! Think Snow!!!!

What I meant is if they are reman cylinders, companies DO sleeve them and replate them.

See fitment tab.
