the RM's arent nearly jetted right. u arent giving it enuf revs, there jetted to give the right fuel when its revining hard, heres a test for u.
get the bike flat out in top gear wide open for a few seconds, put the clutch in and kill the donk, brake and pop the plug, it should be a nice tan colout ( and i reckon u will find it is :wink: )
but since u havent been riding it like ur sposed to ( flat out rev rev rev ) it isnt burnin the extra fuel and as a result fouling the plugs, i dont no the right jet sizes, but go down a size or two.
