I was wondering how often I should replace my rings and piston? I read the manual and it says every five races. The problem is, I don't race the bike and would like to know these answers in hours. My bike puts out a lot of white smoke for the firt couple minutes. What causes this? Is 20:1 sound like the wrong mix? That's what the manual says for the bike. Any suggestions would be great!
