Bike is '05 yz 450. Drained oil and replaced filter. Put little over 1 quart back in. Started bike for 1 minute, turned bike off, waited 1 minute, checked dipstick, half full. So I got impatient and added too much oil to top it off. So I cracked the crankcase bolt (bottom of motor) and drain out what should have been enough oil. Still way over the dipstick at the top of the frame. After waiting 5 hours the oil is still not draining out of the frame tube back to the case. My concern is that I will drain my crankcase dry trying to get the oil level down at the dipstick. Should I start over and drain everything using patience this time? Try to drain some from the downtube drain bolt? Oil should settle back into the case, right?
