Hello, I'm new to the forum and have used the site a lot to gain information. You guys are all awsome and have helped me alot already. Heres my first post. I've been building a 1981 xs650 bobber for a few months now. It's nearly complete but I can't get it to run right. I need your guys help to determine what's happening. I have original carbs with bigger jets in it due to a yo momma exhaust swap and different filters. The bike had no TCI box so I went the mechanical advance PAMCO rout. After wiring the bike up with some help and being sure the bike started right up. Long enough to set the timing and it sounded great. I thought I was nearly done. After running the bike for a little in the garage just idling I gave it some decent revs of the throttle. Still sounded great. I haven't ridden yet due to the fact I still have work to do to it. I gave it another hard twist of the throttle to make sure it was responding well. It revved high then cut out. Now I have no spark at all and don't know what happend. It's like revving it high sent to much voltage to the PAMCO and fried it or something. Please help me if anyone has experienced this. It's a 1981 xs650. New spark plugs, new coil, new advance and all. All other components to the charging system are stock. Fuses didn't pop either.
