Outerwears Airbox cover question....

[smorris1]

I think my bike is running rich because my plug has fouled a couple times with a wet, black look to the plug. Im runnin a 155 main and a 40 pilot with a stage 2 cam, white bros exhaust and k&n filter. I am running the airbox lid on as of now. If I use the outerwears air box cover, will that lean up the mixture some? I went smaller on the main before but it didnt seem to run as good as the 155.

Yeah open up the airbox if you dont want to just rejet.

Mine had a low end stumble when I got it and the plug was black and sooty. I took the airbox lid off and got a pre-charger(outerwears) for it and the stumble went away. Plug is still black but with a little brown/tan color on it. I'd give it a shot as it should lean it up some, though it sounds like yours may be running richer than mine was.

Yeah ill give it a try cause its only $20. I have a jet kit with a bunch of jets but the bike runs pretty good except for cold starts. I use the choke in the cold when i start it so maybe that has something to do with it.
