On a previous thread I asked about new bike break in. One person advised that I reconsider staying with the stock piston on my 05 220 becaues I was planning on putting on an FMF pipe and boyesen reeds. I assume this topic has been discussed on a previous thread, but I am new to this group and did not see it. Can anyone give me a quick rundown on what the problem is with the stock piston on a 220?
Thanks
