Need a main jet size recommendation to start off with?


Recommended Posts

A credit card gap is kind of big. See if you can tighten it up.

What brand stator? Flywheel?

Does the flywheel rattle if you shake it?

I'll look into the gap some more.

The flywheel and stator are both oem

No rattling from the flywheel either

How long you been running the V12?

 

Have you ohmed coil and plug caps seperate? Ohmd stator and pickup coil?

I've been running VP c12 for 10 years.

I didn't ohm the caps separately. Since the bike ran the same with another OEM coil I just assume the secondary circuit is fine.

I ohmed the stator at the 4 pin connector on the right side of the bike next to the kick starter.  I didn't ohm it at the actual pick up.

Here's a recap and the same issue still on hand.

Leak down test is good engine maintained 7 psi for a half hour

Compression was 140 each cylinder.

I regapped the pick up to the flywheel .018" much better spark now.

Cleaned surface rust on stator and flywheel pick ups, flywheel has no rattle.

That sounds like parking brake or another electrical issue

I pulled the harness and inspected all the wires and ohmed all the wires bending and pulling looking for breaks or shorts, nothing found.  Removed all tors connectors and removed parking brake wire all the way back to the CDI.  Since I don't have a good known CDI box to try I'm ripping my hair out exhausting everything possible, until I can get my hands on one.
