Hey all, could anyone please let me know what this is. My bike cut off on me one day and I haven't been able to get it started since. I put in new jets in the carb and new acceleration diaphragm assembly. Also any help on where it plugs into?

Thanks for the help.

That is your voltage regulator, it plugs into the harness.

Thank you very much for the info. Wasn't sure if the bike has an ECU or not. Would this prevent the bike from starting?

I don't see why it would prevent the bike from starting, but I'm not gonna disconnect mine to find out.
