I am trying to test all my electric parts since I rebuilt my carbs and it is running smooth but running at half speed, I didn't change the main gas line or ball yet. I want to figure out where the coil is and is it hard to test. I can't test the stat and rectifier but not sure about the coil

You have 4 coils.
Follow the sparkplug wire back and you will find the coil.

Also, model year is not 1986.

Blue stripes were used 1983 and earlier.

Brown stripes for 1984 and 1985.

Silver/grey stripes starting in 1986-

Thanks can I test the coil , stat, and trigger with a regular volt ohm meter. I tested the rectifier and it does not pass the usual terminal test, but coming if the positive it's charging at 12 v
