The issue is the last time I rode my bike, I ran it fairly hard for almost an hour, then stopped to talk to a friend, and while idling, it just quit. It didn't rev up or make any weird noises or backfires or anything...just quit, like I'd hit the kill switch. I pulled the carb, cleaned it thoroughly, moved needle clip back to stock position #3, moved from a 42 Pilot jet up to a 45, 165 Main Jet, 77 Starter Jet, cleaned the filter, drained the fuel and put fresh back in, and put a new spark plug in it. It won't bump start or backfire. I pulled the plug wire/coil off and held it while I kicked it over, and not "shockingly,"...I got shocked. My next step is to check the resistances on the primary, secondary and source coils per the service manual as well as take a look at the CDI module to look for any obvious failures. I'll also check valve clearances just to make sure everything's in spec. The compression, at least while kicking-it over, feels fine, i.e. no grinding or locking up, so a catastrophic top-end failure doesn't seem likely, but I don't have means to do a leak-down test right now. I wouldn't think it would jump time to the point of not even a backfire w/o some kind of rough-running conditions prior to quitting. My feeling is the problem is electrical since I can't even get a backfire, even if bumpstarting. I've searched the forum as best as I can to find someone with a similar problem but I haven't come up with anything. I'm not hugely experienced with working on it but I know how to follow instructions, hopefully after looking for electrical gremlins I'll find an easy-fix but any help is MUCH appreciated.
