    SL750 burning exhaust hoses

    Does anyone know why the muffler on a SL750 is getting so hot that it burns everything around it? I pulled off the exhaust pipe and manifold to look for restrictions in the water jacket but found nothing.

    Is water supposed to enter the exhaust air somewhere to cool the muffler? Thanks in advance.

    Welcome to the Hulk.

    What year 750 is it?

    93 will have what's called a dry pipe exhaust. There is a TINY orifice that may be clogged that cools the rubber hoses. It should be directly down the center of the 3/4" hose fitting on the tail end of the exhaust pipe. Use a SMALL paper clip to clear it out. The large paper clip is too big to use.

    DO NOT open up the orifice any more. It'll change the characterisitics of the pipe.

    94 and 95 750 uses a wet pipe that injects water into the exhaust pipe through a couple fittings. Check the screen/filter located on the fitting at the top of the exhaust pipe. You'll need to remove the fitting to inspect/clean it.

    Thank you both for the info, It is a 93' and I took a torch tip cleaner and cleaned out the orafice. Although I did not feel any restriction in the hole, I ran it afterwards and everything was cool. Thanks agian.
