    The exhaust isn't overwhelming. It's just more than it used to be. Where it wasn't even noticeable over the past few years I now can smell it during idle while on the platform getting ready to ride. I recently had my gas supply switch in that I was still able to run non ethanol up until this summer. Unfortunately that station closed so now I am stuck with the ethanol gas.

    If you don't idle for long before shutting it down, I would look at the ECT, then the engine grounds.

    Wet and black, or dry? Does the exhaust smell strongly of gas? If nothing is wrong, other than running rich, clean the flame arrestor. If that does nothing to help, remove the two-wire ECT and put it in hot water & measure the temperature of the water before measuring the resistance of the sender. If it's much more than 200 Ohms at 200°F, it's bad.

    Here's a chart-

    MODS- PLEASE MAKE THIS EASILY AVAILABLE!

    Look for a sensor on one of the heads or on the block with one yellow wire and a black one. It's the only thing on the engine with those colors.
    +1 ^^ - thanks for all your posts JimN... I have learned a ton from reading from the University of JimN.

    Where is the Ect located?

    My plugs barely have any discoloration just the tip of the ends had a very small amount of discoloration.

    Verify that the gap is correct. That's not something you want to assume because it can start out wrong, or if it was correct from the factory, it can be changed in transit if the carton was dropped.

    If it's running rich, the plugs will be black/sooty.
    Good burn is typically about a cardboard color brown.
    White is bad (lean).

    Pull them out and take a picture, post it here. There are also lots of photographic guides on the interwebs.
