Muffler or baffle obstructed or something in the exhaust is stopping the flow.dom not run this engine it will burn-up.You may be using too high an octane fuel also.

Hi, the pipe getting red at the header is caused by the fuel mixture being to lean or the ignition timing being too retarded. Check the induction side of the engine for air leaks and the carburettor for blockages etc. Check the ignition timing.
Hope that helps Matt...

The cooling system on the RM-Z450 was designed for motocross and only works efficiently with air flowing through the radiator. You should not sit at idle for more than a minute or two if at all possible. The extreme high output of this engine causes extremely high exhaust output temperature. The pipe temps can reach 600-800 degrees F plus all the way back to the silencer. This is normal on all modern racing 4-strokes. There are a lot of aftermarket products available that help increase the cooling system efficiency. There are also several products that help insulate critical areas from engine and exhaust heat including shields for fuel tanks/lines, the carb/throttle body, rear shock, and plastic body work.
