[QUOTE="ossagp, post: 195954, member: 1650"] the plug and your ease of starting say rich to me. the top end miss is a symptom. another poster on here who recently purchased a used rig had that and he found that his main jet had fallen out. anyway you slice it, i think taking yours apart and setting the float and cleaning it is a good idea. should be a keihin carburetor that should set at 16mm. ask if you dont know how to do it. before you run it check to see that the main jet is within two sizes of stock. what happens is people dont know about setting floats and jet the bikes down as they run richer over time. if you actually fix the original problem by resetting the float you can then be too lean. that ruins pistons and cylinders if you are not familiar.
