I finally got my Jupiter back together, I didn't touch the engine just some wiring and new cables for oem handle bars.
When I got the bike just rode it aroung the block, the handle bars were too low and hit my knee, so the new oem style bars needed new
cables witch I had to order from Italy...
Anyway bike wouldn't start so checked wiring, bought new battery and new 6v coil.
Well the bike started first kick, rode it around the block and turned off, the bike wouldn't start... pulled the plug looked ok.
Next day (today) tried the bike and started first kick.. turned off and same thing will not start... tried with and without Ignition on, choke, and bump starting, couldn't get it started.
any ideas what may be issue?
