Sparks plugs extremely clean. Running lean?
After attempting and failing the Pick Up Coil mod, due to those stubborn 3 screws, I decided I would not be defeated so easily and I would at least check the plugs.
The front two plugs look normal, all is good. Then I checked the back two plugs. They were EXTREMELY clean. They looked brand spankin' new. I'm unsure what to think of this, so I started up the bike, and while it was running pulled the boot off one of the rear plugs. Absolutely no change. The bike continued to run the same. I shut off the bike, pulled out a plug, put it in the boot, grounded it, and cranked the bike over again looking for spark. Viola! Spark!
So, the plugs are receiving spark, but what would cause them to look so freaking new? The bike has been ridden for a bit while I've had it, only about 30 or so miles. But the plugs should have some show of wear even if they were new upon purchase... Right?
My next thought is that one of the carbs is running too lean, or maybe completely gunked up... Any ideas?
