    Could my coil drain my battery, why?

    Hello, while I’m new to posting I am a veteran lurker. I have previously owned a 79 but unfortunately had to sell. I now own a rather troublesome 81. When I first bought the bike it was completely stock apart from the missing battery box. The original ignition black box was shot so I fiddled...

    Hi folks, I've been reading through the threads for a couple of weeks trying to advance my backyard mechanic skills but might be in a little over my head lol. I bought an 82 xs but don't think I'm getting spark. It looks like the PO changed the charging system to a PMA and the ignition looks...

    I Think I Fried my Pamco

    1981 XS650 SH with a Pamco ignition with Eadvance. 2009 tag on the board so I'm pretty sure it's a legit Pamco. I'm trying to diagnose a no spark situation I got myself into. I was troubleshooting a charging system issue, jumped the Reg/Rec, and let it run a few seconds too long. I saw ~16.5V...

    Hello all, recently acquired a 1980 650 Special to add to my collection. Previous owner says they replaced some gaskets and then could not get bike to start. They then put the bike on the "back burner" so to speak and I bought it complete for $200 a few days ago. They think the timing is off...

    PAMCO No spark - bad coil?

    Hi everyone, I've owned my 79 XS650 for about 10 yrs now. It has always been good to me and never left me stranded. After many miles of riding, it finally died on me. It was running fine and I shut it off at a parking lot for maybe 15 minutes. During this time, the key was removed (ignition...

    It just quite, no spark

    I have a 79 650 special. It just died, It smelled like something was hot or burnt but I couldn't pin point what. After pushing it 1/4 mile home the smell wasn't as strong. It has no spark on either side. The fuses are good, the battery is charged, no pinched wires. Does anybody have any ideas. I...
