When on centre stand and in nuetral and making brooom brooom noises the rear wheel rotates significantly while in neutral.. Thats the "drag" ..

It is drag, but it isn't 'clutch' drag.

In neutral on the c/stand and the rear rotating "slowly", meaning slowly enough so you can see the valve going by is OK. Also If your game enough to put you safety boot against the wheel/tyre and the rotation stops easily then thats OK.

If you cant stop the rotations in neutral then you need to "adjust the clutch"..

If it isn't possible to prevent the wheel rotating in neutral then the gearbox needs rebuilding!

If that happens when in gear, or when attempting to select a gear with the clutch lever pulled in, then clutch adjustment may be necessary.

Thanks for agreeing with my point re drag LAB.. Same but different point of veiw.

"If it isn't possible to prevent the wheel rotating in neutral then the gearbox needs rebuilding!"

I disagree with you there... reason being, oil vis, primary chain tension, clutch packin height, other will be able to add.. And also applying more pressure with a real safety boot..

LAB, i applaude your relentless vigour with facts and obsquire articles that are relayed to AN members. Sometimes any of us can be incorrect..

I can only refer you back to what you said:

If it's difficult to prevent the rear wheel rotating in NEUTRAL then it's obviously caused by something other than "clutch adjustment".

Ref finding neutral/clutch drag

Tap dancing with the gear lever is a pain in the ass, but it is on set up and can be cured, maybe it's the indent plunger out of wack with the small detention in the cam plate? Spring etc.

Drag on the clutch can be scarey in traffic if you don't expect it, maybe that's what happened to baz at the henge. Gives you a right dose of the coolly wobbles if it comes out the blue ,if it's dragging get it fixed el pronto.

But I was told by an "expert" all commando clutches drag. What a fcukin fanny.

I have that same problem only when my clutch is not adjusted properly.

No one has mentioned checking the clutch center for wear.
That is where I would start. If the center has dimples where the clutch plates ride then there you are.
Replace mine with a hardened center 3 yrs ago and neutral is as easy to find as the nose on your face.
Of course, cleaning the plates, checking your stack height is very important too.

I'll bet it is Guido

Someone already mentioned it, but I'll say it again, the clutch can act really strange if the primary chain is too tight. If clutch adjustment doesn't do it, loosen the primary a bit and see what happens. It doesn't take much. My 69 is very critical to clutch adjustment (the adjuster in the primary case) and also primary chain tightness. Looser is better. Make sure you read the 'riders handbook' how to adjust the primary chain, it's not real intuitive, you sort of have to back into the adjustment.

Thanks for all the input. I tested for clutch drag and really had none. I then checked the primary chain, and found I'd installed it too tight. Loosened that up and, voila, problem solved.

Great suggestion DogT. !

Now that was funny. You caught my essence. Hilarious!!!

Glad you fixed the problem. Nothing more annoying than not being able to find neutral.

Now you should feel guilty concern of shortening the life of the gear box bushes - forever more - as tight primary chain found cold, means extra tight once road warmed - which can bend main shaft to show up as clutch wobble that only a straighter shaft can fix. Hope you got away with it this time. I believe over tight primary drive events bowing shafts, even w/o actually bending them- are main reason AMC bearing bores get wallowed out ruining the shell. I believe clutch wobble accelerates the center splines to wear more d/t plate chattering un-stable un-squareness.
