I agree, although the roller bearings that are used on the crankshaft tend to have higher friction than babbit bearings, so you can reduce drag with different oil. Since you don't have a wet clutch, you can use 10W30 (or even 5W30 in cooler weather) synthetic. That might improve both mileage and power over 15W40 that most of us run.
