Re: Back Cylinder Not Firing !

First, what was the LAST thing done to the engine/bike BEFORE this problem developed? This may redirect everyone's thinking on potential problem-solving actions.

Chopper, any insights?

I agree with the suggestion above to remove the PC and see if the engine runs both cylinders with the original MAP, or any download that was done. This will help identify if you have a PC problem, or otherwise. If it still does NOT run, try replacing the CPS. And trace the coil trigger wires to make sure they are OK.

Let us know.

TQ
