Phantom6672, before you do anything ride the bike with the new plugs and see if the results are the same. It could be as simple as a bad spark plug. This has actually happened to me. Plug looked good, but was not working . If it was the choke it would effect both plugs. Always check the most simple thing first then work your way back from there. Don't forget to check the plug gap. Leave your rear plug in, pull plug wire, put another new plug in rear wire, start the engine( I know it will be running on front cylinder only), see what kind of spark you see when you ground it to the engine. Also a bad spark plug wire is a big possibility. I had a plug wire that was rubbing on something under the tank and was shorting out because of that. Check your coil could be a bad connection. Good Luck CAHDBIKER
