Yeah, I have several ideas but first you need to figure out what is causing the misfire on #2... FIRST order of business is to determine if it is a carburetion or electrical problem since the compression is decent. Swap #2 plug with for #3. They come off the same coil. See if the problem moves to the #3 cylinder. If it does, then the problem is with your plug wire or plug cap... yeah... I see the new pink wires but it could be the wire or cap OR could be the plug itself.

ok double checked everything only thing left is the carbs, looks like i going to let you handle that, thanks

oh by the way those are red wires, who would put pink wires on there bike??:ohmy: geeessshhh that would just be wrong:P
