Should rear wheel turn when bike cold?

[_pi_]

That is - i start it on the centre stand and the real wheel turns slowly. try stoping it with my hand it seems to be forcing against me and as when i let go it starts again (so probably not from a vibration). NORMAL?!

also - how free spinning should the front and back wheels be?

many thx for any wisdom/experience on this....


oh bike is '03 reg twin spark with 2k miles.

My 2000 GS does that as well....never worried about it, but would like to see what respnses you get

Mine does it - 2002 R1150GS

Mine also does it ...March 2003 GS...Ricky

nothing to be concerned about

 

[(RIP) maverick]

Mine also does it and have wondered in the past if the clutch needs setting? 1994 1100GS

This is your bike so on the balance of probability in your case it DOES indicate a problem!!

Oil drag (cold oil), does it do it when the oil is warm? Try it after you've been for a ride.

Common on many bikes. Good sign for checking if your rear brake is dragging.

Solution

Start it on the side stand !

its cold, thick,viscous oil in the gearbox imparting a drag between gearsets on the first motion shaft to turn the mainshaft gearset, thereby turning the ouput shafts.
This of course, is counteracted by the thick oil in the diff, or bevel geared deduction box on the back axle trying to slow the rotation speed down.

Mine too

My 2001 GS1150 does it and my GS100PD also did it never had any problems though...

just like a torque converter in an automatic car. absolutely nothing to worry about.

Apparently not, seems this time it might be ok

Hmmm

My '94 1100GS does this too. My previous bikes (sportsbikes) all did this and I considered it normal - after all, they all had wet multi-plate clutches which would cause the wheel to turn due to the viscosity and surface tension of the cold oil dragging the friction plates of the clutch around. However, it doesn't make sense on the GS where the clutch is of the dry variety. Theoretically, there should be no connection between rear wheel and spinning engine if the bike is in neutral and clutch lever pulled in.
Anyone got a theory and/or explanation for why this is happening ?. I can only assume it has something to do woth engine vibration / resonance etc.

Duuh ! ? - who said anything about the clutch being pulled in ???

IF it was pulled in you'd have a point
