ok, so i've had my bike for a few months now. Had all the standard problems at first, with chain slipping off, etc...I eventually got everything set properly, and was able to ride it for a month with no problems at all. I upgraded to an iridium plug in July, ran like a dream. Then all of a sudden, I can't get the engine to turn over, starts like it's going to turn over....and then just slows to a stop. There is gunk on the outside of the cylinder head, and a ton of gunk/grease on the chain and sprocket..I may be wrong, but I don't remember there being grease on the chain...I'm really at a loss on what to do, I don't really know how to clean a carb, not sure what else to clean. I think I was running way too rich of a fuel mixture...way too much oil. Any help is appreciated, thanks guys.
