my 98 fatboy backfires during start. i sprayed carb cleaner and when I tried to start, fire came out of carb and a loud backfire from exhaust. prior to this i adjusted my clutch. I don't know if this has something to do with the backfire

 

Did you have the key on when you adjusted the clutch? If not then your clutch ignition timing is 180 degrees out and is causing the backfire. Why would you spray carb cleaner in the carb. How much did you spray? You should give the carb cleaner time to evaporate before trying to crank the bike.

 

I don't know wither to Laugh or feel sorry for that response..

Just laugh. It's good for the soul.

 

"clutch ignition timing is 180 degrees out and is causing the backfire"



Huh...never would have thought of that....

 

It's the carb cleaner igniting.

 

Me neither.
I would have checked the tires for correct air pressure first.

i let the bike sit overnight to dry carb, still not starting.

 

Then in accordance with the line of answers so far...

It could be Ur turn signal oil is low in the right rear...
