I have been on half a dozen rides with my new WR450 and I am pretty happy with just about everything. The only prob I have found is that if I lay my bike down or loop out, the engine oil makes its way into my airbox and spills out onto the subframe. Anyone else have this prob? Anyone know how to fix it? since there is only one quart of oil in it I don't like the idea of losing oil on a ride. Not to mention I have had to clean out the airbox and subframe three times now because of all the oil in it.
