I got back from my first trip to the dunes and during the oil change process i found sand (a lot) all over the oil filter. there was so much sand in the filter cover. i am losing my mind. the oil is black as hell and I dont know how to attack this. I know i need to flush this out but I dont know any thing about tearing this thing apart. I think for starters I will do lots of oil changes tomorrow and analyze its progress. I had about 8hrs at the dunes with that oil change. its not like i wasnt warned. i knew all about the breather hose reroute etc. I wrecked a lot in the sand and the bike was constantly buried. oh and the air filter is clean. new bike for sale?
