So about a year or so ago I did the coil repair and it worked great, for the time being anyways. Well about 2 months ago the bike started running weird every now and then. I have been trying to troubleshoot the problem since then. At first it would stumble only when i was going anywhere from about 40 mph to about 70 mph and i had a steady throttle trying to maintain the speed i was at. When i would twist the throttle even a little bit to accelerate it would run normal again but as soon as i held the steady throttle it would stumble again. As time went on i would be riding and the bike would loose one or two cylinders and then run normal again.
I thought it was fuel so i checked the petcocks and they were fine. I knew the carbs were good because i just went through them. So I adjusted the fuel air mixture a little richer but still same problem. I then thought it was ignition so I checked the pickup coils, because they always go bad, and they were good. Finally today i decided to check out some 4H7 ignition coils that a friend gave me because he didn't know if they were good. I checked them and after replacing 3 out of 4 spark plug caps they read good. Since they were good I decided to check my originals on the bike. No good... the #2 and 3 secondary read 3.5 MEGA OHMS, that is not a mistake it read 3.5 MEGA OHMS. There was all kind of corrosion where the wires went into the brass pin on the coils. When i did the coil repair i didn't use dielectric grease and i didn't seal it. I know I had a reason at the time but I can't think of a good reason now. I think I planed on sealing it later... Haha.
I put the 3 ohm coils on and bypassed the resistor. She is running a lot better now. I will see if it fixes all of the stumbling. I'm guessing it will.
Maybe i should of did it right the first time. But it all worked out because now I have the upgraded ignition coils.
