hey. my friend rides a cr85 and today we were riding andhe was riding it really hard and when he stoped to talk to me there was sparks comming out of the pipe. when we looked inside the pipe it was red hot. i was just wondering if it is normal for the pipe to get red hot on the inside and what the little sparks are from. thanks:o
