Exhaust manifold becomes red hot when revving up engine
Hi there, yes this is normal. Not the best thing to be doing to the bike. It will heat up fast when there is no airflow over the manifold or motor. You must be holding it at revs for an extended period for this to happen. Can I ask you why you are doing that...It is a trick to show off perhaps.....but thats all. If you need to do this sort of thing, to resolve a problem or other, it is always a good idea to have a fan moving air past the engine to cool it, or it will heat up fast, and eventually overheat. The motor is designed to be moving for cooling when throttle is on, not stationary.
