You could try hardcoresledded.com for this, they have a section for F-sleds. I haven't heard of any issues with your problem but haven't delt with the F-sleds that much yet.

plug fouling

Yes, same plug all the time I swapped the fuel injecters and loosened up some real tight wires from the factory, also replaced one spark plug cap that had low resistance the one that fouls plug. I believe it has to be fuel injecter or coil being it the same plug all the time?
