clutch drag

[katana bob]

when I start the bike in gear (especially cold ) it will move forward a bit. will adjusting the clutch cable remedy this or do I have bigger problems? I read where the wrong oil could cause this so I might change it.

Re: clutch drag

In any wet-clutch motorcycle application, cold (thick) oil being pumped into the tranny under pressure will cause the rear wheel to want to rotate even with the clutch in. As the oil comes up to temp, it thins out and the effect goes away, because there isn't enough viscosity left to push the plates against the driveline losses without added input from the engine.

It's common for it to do it on the centerstand or racestand (rear wheel in the air); it shouldn't want to move the bike substancially when the wheel is in contact with the ground -- if it does, yes, you need to adjust your clutch.

Simple test: bike hot, bike on centerstand in 1st, clutch in. If the rear wheel starts moving with the oil hot and the clutch in, the clutch is outside of it's acceptible adjustment range.

If in doubt, have someone at a shop check your clutch adjustment (usually a service advisor will do it for free in a matter of about 60 seconds).

In other words when the bike's cold , that's normal ! 8) If it's hot , then it needs adjusting .
