scubabunny Posted August 23, 2010 Posted August 23, 2010 Please help me. I got a bad tank of gas. Took it for repair. Got a new fuel filter, spark plugs and cleaned the carb. Now the bike will only start with the choke on. I ran it for 5 minutes, turned the choke off and the bike off. Tried to start it with no choke and it will not start. Also, when I start with the choke on, when I turn the choke off, the bike dies. Before all this......It would really backfire upon downshifting and holding the clutch in. Someone had put Vance and Hines pipes on it before I bought it from the used bike dealer. What do you think it going on?? 2007 Yamaha with 4200 miles.
Moderator Airhead Posted August 23, 2010 Moderator Posted August 23, 2010 Could be a blocked pilot jet in the carb.
