    450, in a 1980 cm400E no spark

    Update, I now have spark. Hurrah! The issue was the key missing on the crankshaft, meaning the flywheel was not aligned correctly. On top of that, wear marks showing the flywheel was not spinning at the same pace as the crankshaft. Slow moving flywheel not allowing spark. Everything is back...

    How about grounds? How many different grounds are there on this bike and whereabouts are they located? Anything fused in the ignition circuit?

    Quick question; Is the Stator/charging portion of the bike completely separate from the ignition portion? In other words, if I had a bad stator but a fully charged battery, would the ignition system operate correctly? (at least until battery ran low) Cheers!

    Is there a good direction I should head to buy a new CDI, coil, and spark wire assembly? Also how does this engine know crank position? Is this like a waste spark design where both plugs fire at the same time? Thanks a million for the snapy responses.

    Hi everyone, I just bought a 1980 CM400E that has a 450 twin (6 speed) swapped in. Trouble is, previous owner modified the ignition system in a way that removed many OEM ignition components. Quick questions to those who know; can I revert to OEM CM400E wiring system and components (CDI, coil...
