Britbike forum Forums Thread Like Summary - b50mx Electrex Ignition

Hi there, I just purchased an Electrex ignition for the b50mx that I am building up to race in vmx. Can someone tell me if the coil needs to be grounded? Also do I use the stock crankshaft nut without the tab washer? Thanks.

Thanks for the photo

I have the same unit on my T90 race bike

I did ground the coil (negative ground)

If you can use the tab washer use it, if not, a dab of red loctite and torque will be sufficient
