I have a 17 sb pro s 600 3200 miles runs great but been fouling mag side plugs. Will go 200 miles strong all day turn next morning foul a plug warming up. Comp is 115 both cly. I’m lost in what it could be like I said it runs hard and strong. Injector? Seal? Coil? Maybe just some sea foam ?
 
I'm experiencing some issues on a similar sled, just curious once the plug is fouled I assume it's obvious with one cylinder firing. Mine seems to idle and run good but seems like it's missing some top end power. Don't think it's a plug, suspect my exhaust valves need to be cleaned.

Your plug only foul out while warming up?

Mostly on warm up when I go to pull out of camp it could mag side I replace plugs runs good all day then when cold again it does it again. Idk. It had fouled in middle of a ride already also but only once.
 
I would start by running some sea foam or K100 through it, could just be a crappy spray from that injector not atomizing the fuel.
