I am new to riding really just got a used 03 blaster a few months ago...it blew up when we bought it so i fixed it removed aftermarket intake and i replaced the oil injection we thought the plug would foul because of over rich gas i cleared out the rest of the mixed but it fouled still is there something i could be doing wrong? When me and some friends pulled the plug(out on a trail) it mwas wet, black, and were sure it fould so we cleaned it up skrewed up the gap but ran it back.
