Anyone have any experiences with these pistons? See quite a few of them on ebay.

They are pretty new to the Raptor. I have used them with good success on other bikes such as the Banshee and Blaster. They are a cast piston but they add alot of silicon and teflon coatings which helps for wear. I sent the person selling them a email asking if they make a kit in the (686) .080 bore and how much they weigh. These pistons should be lighter. They have a flat dome so they are probably only available in stock compression. If I didn't want to up the compression I would give one of these kits a try.
