Is anyone using Royal Purple?

The only reason you are not supposed to run car oil in a motorcycle is because of the clutch. Certain synthetic car oils have certain "friction modifyers" that destroy a bike clutch. That's exactly what happened when I ran Royal Purple in my bike. Ever since that day I've been running Mobil One car oil 10W-30 in all my bikes. Mobil One does not have any of the nasty friction modifyers that destory a bike clutch.

so maybe you should use the right oil for your application instead of ripping on an oil that wasn't designed for what you were trying to use it for. just my $.02
