    oversized pistons for gp1200r

    Where can I find oversized pistons? The engine was sleeved by previous owner and I have 2 cylinders that need cleaned up.

    WSM makes them up to 1mm over I believe. If you use WSM, get the "platinum" series. SBT also has them...

    Thanks, just ordered the WSM's. Read some bad reviews on them, hope they work out okay. They will just be on a rec. ski, with a few mods.

    Don't tell anyone around here, but I have used, and am using them and haven't had an issue yet. I've used them in my snowmobiles too. They all seem to melt the same, LOL. I just can't stomach $130+ for a stock piston...its absolutely ridiculous. I can get custom forged Wisecos for my LS2 for less than $100 a piece!
