40 grade oils aren't resourse conserving, so it might not cause clutch problems. You could have better idea of that if you could find a product data sheet and see how much moly is listed. Based on how other automotive 5W40's do in shared sump motorcycles, I would expect it to shear well out of grade maybe in just a couple thousand miles. I wouldn't put it my bike. Use it for the next oil change in your car, or give it to someone who can.
