Sometimes My CRF wil miss fire (mostly in the last 2 or 3 gears) Its only two months or so old, so I figure the plug should be good. I looked at it and the bottom few threads are black, but I cant see why i would have to change it yet. I think there may be a little bit of dirt in the gas I had just put in.(Ive ran most of the gas threw it and plan to run it almost dry then refill it) Will a little bit of dirt hurt my engine?
