Hi, lately I've been taking my KTM 250 exc to the dunes, I was wondering if there is anything I should be keeping an eye on when taking my bike in the sand, I really don't want to break it. I've been cleaning the air filter after every ride in the sand, I put it back on with grease to seal it, changing trans oil after ever 2 rides, and thoroughly pressure washing the bike after every ride in the sand. I keep the cables cleaned and oiled. I pulled the spark plug and it is a dark brown color, and there is a little oil dripping out the silencer so I'm assuming the jetting is rich enough. It's never boiled over. The only thing the sand seems to be ruining so far is the chain. Anything else I should be maintaining after a trip to the dunes?
