ok kinda new on jetting but i keep fouling plugs after only about 40 mins of ride time barley any black on them (a little) but they are really oily. At first I thought it might have been my jetting. running a 240 main not sure of pilot jet size. BUt i was thinking that maybe i need a engine rebuild because i am thinking that the amount of sheer oil on the plug wouldn'tr come through just fuel, and maybe it is coming from the bottom end. Just wondering if it was possible for the oil to come from the bottom end to foul the plugs that quickly? BTW this is on an 87 suzuki lt250r
