bogs when clutch let out

Ran into this exact (100%) same situation working on a friends police special....
Not sure yours is configured the same... :blush:

Clutch perch had a micro switch!!!!
Look at your left handle bar clutch perch, see a 2 conductor sleeved cable assembly going to the bottom side of the clutch lever assembly/housing...?

Works the same principle as the side kick stand switch....

Anyhoot, just a thought, worth confirming...

thanks, I'll get out the multimeter and check

Then It died when warm. Pickup coil was five ohms out of spec on the front pickup when hot. Now it won't start consistently and it boggs...

So you still have a pickup coil that is reading 5 ohms out? If so you may be losing 2 cylinders. One pickup coil runs 1 ignition coil, which fires 2 plugs.

issue apparently solved with different pickup coils.
