It started out by dropping spark on mag side cylinders first then eventually dropped spark on other two cylinders. Replaced cdi box with two different boxes, and still no spark. Lighting coil stilll works because headlight lights up when pulled over. Probably stator or pulsar coils. Wondering if anybody knows what the stator is supposed to ohm out at?

Went to Yamaha dealer today. They had a little book with some good info in it. Here is some.

Pulser coil / White with red to white with green 505 ohms, + or - 10 %.
White with blue to white with red 505 ohms, + or - 10 %.

Charge coil / Brown to black with red 2.55 ohms + or - 10 %.
White to black .33 ohms + or - to %.

Grip warmer coil / Yellow with black to black 1.02 ohms + or - 10%.

Primary ignition coil / .2 ohms + or - 20%.

Secondary ignition coil / 4.9k ohms + or - 20%.

Hope this will help.

Download the appicable manual, there should be electrical specs in the back.

You probably already checked this but if not, make sure you have a good ground to the coils.
