Ok guys I need your help again. Ugh!!! So I was riding today and all was well. Machine was running fine no missing, spitting or sputtering but all at once noticed it did not have any power. With pedal to the ground it would go only about 20mph. (No codes or not lights came on) so I turn the engine off (big mistake) would not start back!! Checked fuses all look good, you can hear the fuel pump kick in and it will crank but won’t start so I check the spark plugs. The spark plug to the far right isn’t firing so... get two new plugs put them in and still not starting. So I check to see if it’s firing and the same one still not throwing a spark. I switched the wires to see if maybe that was the problem and still no spark. I’m thinking it’s the coil so got new coil and plugs and still nothing.

I would check the wires on the plug to the coil, and chase that harness back to look for any fraying or rubbing or anything like that, sounds like it's seeing the signal to fire the MAG cylinder.... outside of that...Crank position sensor maybe? I would think that would throw a code, but it seems like it's not getting a correct reading for engine rotation, specifically the MAG side....I would think it would have to be that, or the ECU if not the wiring.
