Hey I have an interesting question. Last night I was in my garage counting down the days until riding season starts up here. Anyhow I decided to start my bike ,06 636, The rear tire is up on the stand but I also noticed that the wheel was spinning like it was in gear. Is this something with the clutch adjustment or am I going nuts.

 

I wouldn't think that a small amount of wheel rotation is of concern. If you can stop the rotation with your hand pressure, then no big deal.

 

its normal for it to spin a little, but if its spinning enough to move the bike then its out of adjustment.
