Re: Pit bike backfiring!!
your right, if your plugs sooty, then your misture is far too rich.
you'll need to adjust the mixture screw on your carb, which's area will depend on the brand of your carb, either a spring held screw on the side (VM) or underneath. the plug should be sort of blacky browny, run too lean, and the bike won't run good (over heat). Good luck. EDIT: In Future, try not to use caps ALL throughout your message, it gets annoying. :) |
