Looking for some thoughts on this.....I bought this 2002 WR426 a couple months ago - its near perfect and the owner was meticulous. To my own fault, I never bothered checking the oil level (after owning 35+ cycles, I should know better). I rode it about 20 miles, 95 degree heat, getting on it fairly good in some open trail riding. Tonight I decided to change the oil and filter and discovered it had maybe a half quart in the bike. I cleaned the air filter, did the oil and filter change and replaced/flushed coolant. The bike has used Honda HP Synthetic oil since new and maybe has 800-900 miles total on it. It seems to be running and shifting fine. Any thoughts on if the motor was damaged during my 20 miles with half a quart in the crankcase?
