97 700SX - PSI pipes - jetted at 142.5 in all three w/ 45 pilots - stock head gasket - clean carbs- .
Is it possible that my three ignition coils could be going bad and causing me to foul plugs for no good reason?? While riding on friday in 29 degree temps, i fouled several plugs during the day. We rode allot of powder but never did I foul a plug while in the powder. It was always on a nice trail that I would foul a plug. Going at a good rate down the trail, stopped for the grommer to go by, took back off and fouled a plug. I could understand if it was in the powder but the sled ran fine all day in the powder. I have replaced the stater a season ago. Spark plug caps are also new then, new plugs installed. CDI and the three ignition coils all are stock and have 5500 miles on them.
Sat I rode all day without any problem - 18 degrees. Both trail and powder.
Could the ignition coils have a mind of there own. When I did foul a plug it was not real black as if they were fouled but it would not be fireing on that cylinder any longer untill I changed the plug. It also was not always on the same cylinder, more of a random thing.

Tod,
I would guess something with the oil pump could be cuasing this. Make sure your cable do not pull apart.

Yes i did check the cable. I did not measure the freeplay but i did check to make sure it was not apart and seemed to be working ok. Freeplay looked good as far as a visual.
oil pump is still the same one that came on the sled. same as day one..........

That is strange.....How much oil are you using in 100 mile trip???
Ya know now that you jog my memory I did have my oil light come on at the end of the night on the way back home. And we did not do that many miles but we did do a hell of allot of powder playing. I'll have to check that freeplay.
If the pump is bad does it go to wide open??

yes. the pump will usually fail dumping tons of oil into the sled....better then it blowing 
....keep me posted.

....keep me posted.Tom
OK - Thanks
But why such a problem on friday and no problem at all on saturday??????
temp, will affect it quite a bit....had a similar problem on my brothers sons SX-R and when it was cold it was not to bad but as the temp warmed .....plug after plug....dont quote me on this, just giving you my best guess.
