Hello again great knowledgable ones.
I come to you once again seeking council.
quick stats recap: 78 stock. points, original rotor, seems like original coils, pretty much everything but the exhaust is stock. bought it used and brought her back from the grave.
Here is the situation: the bike has been absolutely tearing since I rejetted. I mean, holy hell does it scoot. Ive got 2 into 1 pipes and stock airboxes, so I went up 2 on the mains and 1 on the pilot and that seemed to do the trick. However, since making that change I've had some mean backfiring, the first of which blew my carb out of the boot. So after riding for a couple days I decided it was time to deal with the backfire. so I pulled the carbs, checked the boots (seem good), fixed the tangs that got bent from that blowout, cleaned them and put them back. Then I did cam chain, valves, and timing. I should mention the top points connection was sparking and the bottom was not.
heres the kicker, I went to start her up for a test ride and like an absolute dumb*ss forgot that the left spark plug wire was not hooked on. only noticed after I kicked it five or six times. So probably fried the coil but I couldn't figure out how to test it so I thought "well I already beefed this might as well see what happens". So I plugged in the spark wire and kicked her and she REALLY reluctantly came on but was backfiring like a banshee. both exhausts got hot evenly so I thought okay maybe I didn't burn it out, lets see how she rides. so I took a lap around the neighborhood and boy, she is not okay. Super jolty and weird, backfiring at all rpm. so im assuming that coil is bustered, and the cylinder was only firing intermittently. also after riding I noticed gas on the gearbox which seemed to leak out of the bottom gasket.
so with all that in mind im a little lost and frustrated. I am open to any procedural advice, and probably need some new coil suggestions. I have read everything I can find but I have so many symptoms that im not sure where to start.
thank you for anyone who had the time to read that.
