    Hello everyone! So the new Yuasa battery came we filled it charged it and put it in the bike. Tried the starter and nothing. Tried kicking it over and nothing. Then my buddy rode it down his driveway trying to jump start it, he said it sputtered a couple times. We tried a couple more times and nothing. What the hell?
    Anyone have any ideas? Thanks guys!

    Is it possible that when you replaced the points and condenser that the wires are making ground at the points connection? Or the points/wires grounding out on the cover?

    Yes that is entirely possible. What would the points look like if that were happening? There is a bit of arcing on the points right now, is that normal? Thanks for your help with this!

    Large arcing usually means the condenser isn't working well but a tiny bit is sort of normal.
    We used to soak a distributer cap with carb cleaner and put it back on after an apprentice did a tune up just for fun, always blew up because of that tiny arc.

    Good day all, Happy New Year! The Christmas season brought many miracles, specifically my bike is NOW RUNNING! And running well too I might add. Turns out the problem was the ignition coil. I think it got fried when the key got left on by someone (not naming names). Either way it's running, now I can start fabrication of new fenders, shrink down the seat, new bars etc.

    Anyone know where to get the little 6 volt light bulbs for the indicators?

    I'll post some pics or video soon! Thanks to everyone for all their help!
