[QUOTE="ossagp, post: 186896, member: 1650"] I would start with mixing the oil to the manufacturers specs. Clean the carburetor, inspect the jet sizes, and set the float. (dont miss the last part of that sentence.) compare the jet sizes to stock. If they are within 1-2 sizes on the main jet and within 3 sizes on the pilot jet I would ride it some more and see if it runs cleanly and without fouling the plug. Look at the plug for color etc and see if you like the way it runs in general. Jets are spendy and it almost seems that particularly on on older bike with the gas we have today as compared to 89, no one seems to think opitimum jetting is oe. Setting the float will very likely lean your overall mix out, unless it was just reset. Few people EVER do it, so don't assume it has been done even or especially if a shop has had it recently. The float level ALWAYS raises as the rig is ridden. Default setting on the airscrew is 1.5 Places like bike bandit at least show an exploded view of the carburetor so you have an idea of where things go. with digital cams now it is easy to record that too.
