I am watching 3 pistons on ebay and i was wondering which one out of the 3 would be the best. The first one is a cp piston with 13:1 compression. 2nd is a JE 13.5:1 and the 3rd one is a Wiseco 13:1 comp. The reason im getting a new piston is that i want more power also my rod bearing went out on the crank. your help would be appreciated Thanks Shane

I'd go JE or Cp. Had good luck from both, heard some horror stories about Wiseco.

Just about all the guys making serious power are all running Wiseco's. All the pistons are going to give you similar reliability. Most horror stories are a result of abuse somewere down the road. Not warming up, low oil, overheating etc.

jande pistons are pos. go with the wiseco or cp. make sure you go with forged also.. NEVER get a cast piston unless your running all stock compression and are letting your little sister ride it. spend the extra money on the forged.. save you even more in the long run if you plan to ride it hard
