Picking up a used Kawasaki KLR650 tomorrow. Manual calls for 10w-50.<br /><br />There appears to be as much conjecture, opinion, and downright anger with motorcycle enthusiasts as there are with boaters when it comes to oil.<br /><br />Anyone own a dual-sport bike, what do you use?<br /><br />Anyone been to copper canyon, Mexico.... or any other fun rides?
