Afternoon Cmyers41 OK, go back over what you did, is the coil full plugged in, are the injectors fully plugged in. Try holding the twist grip open about 1/8 throttle then try to starting.

OK, disconnect the L/H side plug wire, then ground that plug wire (so it doesn't arc internally inside the coil), then see if it will fire off at all on the R/H side. You will probably need to use the choke, or hold the throttle open a bit to get it to stay running. Link to comment

Did it with the plug wires still swapped...ran on the R/H cylinder only. Did it after switching the plug wires back over to normal, would not turn over. Link to comment

That is pointing to a bad plug wire (but it was OK when you measured it way back in the beginning) Try measuring the total secondary resistance. Back to the 200K scale on your meter, then with plug wires back to original position on coil measure resistance from one spark plug wire (spark plug end) to the other side spark plug wire (spark plug end).

Afternoon Cmyers41 Yes, you want to see somewhere above 18K & below 25K so you are right there in the ballpark. OK that makes it confusing-- all test good but you still seem to have a dead R/H cylinder with the original plug wire configuration. Personally my Next move would be to run a compression test to validate the R/H cylinder, but you don't have that option. It is kind of pointing to the R/H side of the coil having issues as you can't seem to get a cylinder to run from that side of the coil (with all you have done go back over what you have done to see if you ever got a cylinder to run from the R/H plug wire side of the coil). Probably put a new (good used) coil in the bike then see where you are at. Link to comment

Cmyers41 Posted October 18, 2020 Author Share Posted October 18, 2020 Negative, only L/H. I think finding a working coil is my best option. Any suggestions? Link to comment

Cmyers41 Posted October 18, 2020 Author Share Posted October 18, 2020 Thanks for all the help!!!! Once I get a new coil I'll post the results. Coincidentally enough, it is the right side of the coil that is cracked open / damaged. So maybe that's why the right side isn't work? Something (moisture) got up I there and screwed with things?

AZgman Posted October 18, 2020 Share Posted October 18, 2020 Got it. How about the one on Amazon? Link to comment
