My carbon fiber pipe protector by E-line is slightly burning. Has anyone else had this problem? According to the plug my bike is not running lean, but the pipe is getting very hot and turning purple near the cylinder. It also has a small crack in pipe (getting repaired)! Could the crack cause the pipe to overheat or did the pipe overheating cause the crack? The bike at slow speeds ie. tight trails does not burn the protector. But any motocrossing burns the hell out of it and quick. Any replies would be helpful.
