What coud be making my pipe got red hot

Even when I run my bike pipe is so hot cant ride safely as I have to lift my leg out of the way bc pipe is burning hot. Without touching it already have burn scars on my leg.

get a timing light and set the points.

make sure you have a healthy spark

I would check your coolant first off. Your bike also may be running a little rich (too much fuel) which can cause greater heat. I would try adjusting the little black knob that sticks out of your carburetor, this will adjust your air-fuel mixture. Be careful though, adjusting too much at one time and then riding it hard could damage your bike, i'd adjust it little by little and then ride a bit after each adjustment. See if that helps you work out this problem. good luck

the pilot jet is too only make the bike idle so it wouldnt be this is the engine have lots of oil in the engine

change the jetting...youcan contact FMF for thier setup recommendations for running that pipe with the bike...very common problem and jetting will take care of alot of the issue
