Have you replaced your Ignition coils??

[Tod]

If you have replaced your ignition coils I would be interested in the problems you were having that made you replace them.

I know there is a spec on them as far as measuring the resistance at a certain temp.

I will foul a plug every once in a while for no good reason. Oil pump is adjusted to be lean, carbs are clean, sled runs great but then it will just foul a plug out of the blue.

FYI - My sled is a 97 700SX with pipes. Same jetting the last 4000 miles, no problems with plug fouling before

Ignition coils...Todd

Check the connector plug coming up from the stator for burn marks ( from arcing ) it's the 3 wire plug that continues to the coils.........try running the motor in the dark, and watching for an arc...........the connector pins might have loosened up, and will cause this to happen. I
just went beserk trying to solve the same problem on a 98 700. And that's what it was.
