With the bike on the centre stand, does the rear wheel turn (slowly) while on idle and neutral?
Just wondering if they all do that.

Yes, shows loose bearings, loose freewheelers on the trans, loose meaning, I have less friction than you, if my wheel moves in N w/idle. It's not a worn thing, it's a good thing. Mine does it, and if you run a static spin? I think we had 6 or 7 turns with engine off. Engine running, that wheel moves with the clutch basket jut about.

Thanks Hub, nice to know they all do it - otherwise it's easy to suspect maladjusted clutch or whatever else..

Every bike I have ever had does it, except maybe the Husqvarna.

Mine does it. Busa does as well. I wondered the same thing as you..."is the clutch wearing out?" No, it's just cold sticky oil not letting the clutch plates slide apart. It will notturn as much or at all when the engine is good and hot.

YW...

I went from memory, so here is the opposite.

13127 is the fixed gear teeth on the shaft. This spins splined to the clutch basket.
13128 is the output shaft, or counter shaft.
13262 is the freewheeler designed gear.
13262G is a splined gear, so this slides back and forth to lock into a freewheeler for any of the gears to mesh as a 1 output ratio of a 6 gear combo.

As 13127 spins fixed to the clutch baskets, this spins the freewheelers.
As the fixed gear causes the oil to cling to the freewheelers , this causes momentum to move the 13128 output shaft.
As the engine runs, look at the hole near the gear of the 13127 shaft. Look at 92028 bushing and how that too has a hole in the middle of the bushing. That's forced oil pressure out that hole of the shaft, then the hole of bushing is lubed to the ID and when flows to the freewheeler, this lubes the OD and ID of the freewheeler gear.
As that oil pressure is now both locked by the splash onto the gears, the lube forced out the holes, this tends to carry momentum to the output shaft as now you see the wheel spin on its own.
AS IF you could not tell a pair of steel bearings spinning as opposed to ceramic bearings spinning that wheel. What's left to cause drag? The lip on that big output shaft seal. You want to see this move as it does. Shows lots of friction being freed up... which is a good thing for gas mileage and top speed numbers so no drag happens as if the rear wheel won't move in the same scenario.

Yes thats normal, every bike does it. Now if you stop your tire and your bike dies you have problems. lol

Normal. Although neither my now sold '04 Honda RC51 nor my '13 ZX do it. Luck of the draw I guess. Or maybe I'm just a better person
