Question about 2000 Harley Davidson XL 1200 C Sportster Custom
If it's misfiring and running hot, this has nothing to do with a voltage rectifier. It sounds like you've got an extreme lean fuel-air mixture for some reason. They do come from the factory jetted very lean due to EPA regulations but if you've got a manifold vacuum leak, it will cause a misfire and the engine to run extremely hot. I'd check the manifold seal behind the carb, the vacuum hose fitting on the backside of the carb, and the gaskets where the intake bolts to the head. If the slow jet is a #42 jet, I'd go up to a #45 and put a 0.020" thick washer under the needle to raise it just a bit to erichen the mid-range mix just a tad. That is if the bike still has the stock carburetor on it.
