I’ve been back any fourth with my 05 660 dealing with what i thought was carb issues. I cleaned the carb starts right up it idles fine open the throttle in neutral and its fine. if i open up to full throttle on the road for 50 or so yards it blacks out the spark plug and it stalls out. I’m going to send it to the dealer because I’m tired of fighting this stupid thing id rather just pay to have it fixed. But is there anything i should try before i throw my money away.
