I just bought a 2007 C90T. The bike sat for almost 2 years. I brought it home on trailer and removed the gas. Replaced with new fuel. The left side throttle body was a little black so I sprayed it out with throttle body cleaner. I changed the oil and filter and put new plugs in. Both plugs were black. I have not had it out for a good run yet, but it is running real rich. I can smell the fuel as it runs. Seems to run not too bad. The bike is all stock. Is there any help anyone can offer. Is there something else I should do.
