Check for cracked Y pipe at rear cylinder. Check for loose pipes. Is it misfire or decel popping? Check intake gaskets.

That has been checked. Has Rinehart true duals. It started it about 3 weeks ago. If you look at the throttle body it has two ports. You can see the sparks in there.

Have you had your fuel filter changed in the last month? It is possable that you have a leak inside the tank. The plastic hose from the pump to the filter have also been known to spring a leak. When this happens the fuel pressure to the injectors drops to low and the bike will back fire through the T-body. I just fixed that issue today with my 03. I tested the pressure leaving the tank and it was at 30 psi running and after fixing the problem it was at 56 psi and runnig good.
