I see Wiseco has come out with a new piston. They call it a GP piston and it appears to cost another $20. It is supposed to give you a little more top end and be more durable. I don't have the article in front of me, but wondered if anyone has used one yet? I'll be putting a new top end in my 02 YZ125 in the next month or so and am looking for cheap power gains. Thanks!
