Hello I’m new here. Let me start from the beginning. I was riding along in 4th gear and came up on a mud hole, so I dropped down to 2nd. While waiting for others to catch up it shut off. No luck restarting, so I tried my starter spray. It would start and run for about 3 seconds. Got towed back. No fuel pump clicking after pressing start button , so I assume , it has to be fuel pump. I use starter spray to load on trailer, then to unload and put in garage. Test fuel pump with jump box, it does not run. Bought a new one and changed it out. Then the old one started to work when on jump box now, go figure. New one is clicking and pumping fuel. Bike will crank over but not start. So I use the starter spray, figure the new pump needs to prime, it runs as long as I keep spraying bursts every few seconds. Then it back fires LOUD. 2 or 3 times. Now won’t start even with spray. So I check for spark, there is none. So I buy a new coil, no luck. I buy a new CDI and still no spark. I’m not that upset, those were original parts( 27 years old) so I know I won’t need to worry about them now. I’m just at a loss now. Don’t want to just keep changing parts and hoping that’s it. Any help, thoughts?
