Just wondering, cuz i bought the bike from a dealer and they arent sure if it jetted, and im not sure if it has been jetted, and usually with jet kit they have drilled it for the adjustment screw right? So if its drille chances are its jetted.That link does not answer his question. To get to the fuel mixture screw, you need to remove the carbs from the bike. Next to the float bowls, there is a metal cap that you will need to drill out to access the mixture screw. Are you installing a jet kit? or just adjusting for altitude changes?
