hello I was hoping somebody would know for sure what the piston on the left is. it came out of my yamaha warrior when I bored over. I thought it looks like a wiseco but was hoping somebody would know for sure. the one on the right came out of a parts warrior and is for comparison I know its oem. and also do both seem to be in pretty good condition? the left one seems pretty good considering ive owned the four wheelerfor around 2 years and the guy before me said he hadn't done anything but oil changes and brake pads it was a 2000 model. and the right one came out of a 94.
