heres what happened: i was installing a trailtech stator with my 04 wr450 laying on its side, i cut a piece of shrink tube and a piece maybe an inch long fell into the case. at first i wasn't sure it went in there. i emptied the case, nothing came out. did an oil change and i ran it a bit. checked the oil and it was way full. emptied the case barely any oil came out. oil filter was covered by a mashed up shrink tube. ive done 4 oil changes including taking off lines and filter in resevoir. the other day the oil was all in the frame resevoir, not flowing thru. the oil lines and filter are off right now and empty of oil. is there a way to flush the oil lines in the case? tried compressed air, one side pushed thru the other didn't. any suggestions?
