i have looked at pinching before and i still dont have an answer to two things. one, will a pinched sleeve last about as long as a new sleeve and two, how many times can you get a single sleeve pinched? im only 15 and my picco p7r evo just wont idle unless its got a brand new plug. I am trying to decide weather to get a go-tech 5 port or re-pinch my picco. got an oppinion?
