Hey all, I'm a newbie to 4 strokes and have a question regarding my 08 wr450... Yesterday after a short ride I noticed oil dripping from my airbox down onto my swingarm. When I opened up the sidecover I noticed a pool (approx 2-3 ounces) of oil resting at the bottom of the airbox. I'm assuming I didn't get all of the old oil out before I added new oil during my last oil change even though I used both drain holes and compensated for not replacing the oil filter. Is this common if you there is too much oil in the bike? Thanks for the help.
