In cases like this you should replace the exhaust gaskets between your pipes and the cylinder, and sync your carbs. My '02 1100 started doing the same thing, and after replacing the exhaust gaskets and syncing the carbs, it runs great again. I know this post is a few years old, but maybe someone such as me looking for information may stumble upon this.

Yes the check voltage at the battery; you should have 14.0 volts at 5000 RPM or just rev it up high if you don't have a tach. ANYTHING below or above 14 is not going to work. 99% of the time it's your voltage regulator. The part is 120.00 and easily installed.

99% sure it's your voltage regulator.

I have a 2002 Vstar 1100 that made a loud pop at a stop sign. Tried to start it and there was a loud banging sound. I'm in the process of tearing it down and installing a new starter that WAS twisted and new heavy duty starter clutch. I think it all stems from the bike not starting well when hot. The carbs are not jetted right and/or gas is bypassing the gaskets in the carbs. The motor floods with bypassed gas and sits there. When you go to start it, you crank on the starter a least a couple times before it will clear out and start. With all the compression, the starter has a lot of torque on it and sometimes it kicks back when you let off the button. Well I will let you know if this solves the problem. RIDE ON BROTHER!!!

Running rich usually will not cause backfire. Running lean usually does.

Aftermarket exhaust? May not be enough back pressure.

Check your clutch cable free play.

I believe if it continues to run rich when hot, it will leave excessive fumes in the exhaust, creating an explosion that sounds like a backfire.

Dental floss works well with no damage.

I have a 02 V-Star 1100 cc. I cannot get gasoline past the carburetors to make it fire up. I changed out all the relays, I've changed starter clutch twice; I broke the first one brand new when I put it on. I changed throttle positioning sensor, clutches, all relays, fuel pump, everything I can think of and I cannot get it to start up. What am I doing wrong? It's got me to the point I don't want to sell it, but I'm fixing to. I don't understand what the problem is. Please, please help me; I'm at my wit's end with this bike.
