Hey guys, I rebuilt my 500's topend and blewout the paper base gasket. While replacing the paper base gasket, I couldn't help but notice the piston top was hardly discolored and not black like I thought it should be. I've never messed with jetting before, but doesn't this sound like the bikes running lean? I'm not sure what jets are in the carb and don't know where to start to fix my problem. I do know I don't want to burn my bike down after JUST rebuilding the topend.
