I see pictures of peoples spark plugs (two stroke plugs) on here and they barely have any oil or carbon built on them at all. On my 2004 rm250 and on my last bike (2000 rm125) my spark plugs would be all black from oil. Is my jetting to rich? I have never touched the jetting on either bike besides the idle screw.
