I just put a boss on my ped and it sounds awesome, like a million dollars LOL
I also have white smoke but am not worried about that since I read the earlier comment.
I noticed one thing though that the centerstand hits the pipe when I put the stand up, I didn't realize that and it hit the pipe, now I know to put it up gently. Does anybody know if that is normal? It's on a Maxi btw.
Oh, does anyone know what jetting to use with a 65 cc metrakit, boss pipe and 16 mm dellorto carb?
