Title: Clutch Drag
Post by: clubman on March 30, 2010, 01:21:00 pm
I've happened to start the bike on the centre stand a couple of times recently and noticed on both occasions that the rear wheel turned. So my diagnosis is clutch drag. Is this normal for the G5? Is it anything to worry about? And how would I stop it? Sorry if I sound really stupid!  :-[

Its normal for the rear wheel to spin with the motor running and the bike on the center stand. There is always a small amount of friction between the spinning parts. With the wheels on the ground if the bike wants to pull forward you are getting into clutch drag.

It won’t be clutch drag if the bike is in neutral on the mainstand.

It’s just the viscosity of the engine oil managing to create enough drag within the engine to turn the gearbox output shaft, the gearbox sprocket and rear wheel. You should find it happens less when the engine is hot, if the clutch is working ok in normal use it’s nothing to worry about…they all do it.

As everybody has pointed out, it is OK.  Here is a video of my G5 - the rear wheel turns when bike is started and is on centre stand.  I purposely recorded and posted it that way !
