I wash my RKC on a stand. Wanting to check the fluids, I started the engine while the bike was on the stand and in nuetral. I noticed the rear wheel moved in a clockwise rotation. It also rotated faster if I gave the engine more throttle. Remember the bike was in neutral. What makes the wheel spin and spin faster with more throttle?

Your clutch basket is spinning, and the primary chain is spinning. The hydraulic action of the oil is making your output to the rear wheel to also move. Speed up the flow, and the wheel rotates faster.

 

Yeah all bikes do it even sport and metrics.....

 

Vehicles do the same thing

 

I was going to say magic, but I think your answer is probably more correct.

 

Thanks! Thats makes sense to me.

I still like the magic answer. It's more fun then the technical answer. I was going to say tire Gnomes are running inside the wheel for exercise.

 

Gremlins??

 

Vibration Harmonics? Well it sounded good!
