First of all let's point out the facts :
- BACKFIRE is a sneeze, or cough, popping or little bit of flame coming out of the carb or intake.
- AFTERFIRE is popping out of the exhaust.

So we're going to tackle "afterfire" first:

If your bike is afterfiring, your pilot circuit is too lean. Start by adjusting your air fuel mixture screw(s). If that doesn't fix the problem, the answer is in this VIDEO!

This issue could also be indicative of an exhaust leak, a valve adjustment being out or potentially a vacuum leak (rare).

If your carb is coughing, that's also an indication of a lean condition. TJ explains and gives more details IN THIS VIDEO – so WATCH NOW!!!
