Hi All,

I reviewed a number of posts regarding the front sprocket and the 750's appear to have varied offsets and retainer plate set ups.

Could anyone please provide a brief explanation of how my configuration actually works before I do the "deep dive" and make an expensive mistake. i'm looking for tips and tricks to service and lubricate it. It has a few millimetres of play too which I believe is normal.

Thanks for the info.

It looks like the bolt & washer might be missing……...I'll take another look at it.

the bolt is there. You can see it sunk in the adapter (#16).
#14 is a shim that exists in different sizes. This is to set the axial play correctly.

You're right, thanks for the help much appreciated.

The washer, #16, is not a normal washer. It is a stepped spacer, and the step is just a bit more than the thickness of the flange on the sprocket. The torque of the bolt tightens up through the spacer onto the shaft, not through the sprocket. The sprocket floats a bit. If you use a normal washer in place of the special spacer, the bolt will come undone rather quickly.

#14 may be a warpy washer that simply preloads the sprocket to reduce rattle. Should always be a little bit of free play in the system so that the movement of the sprocket doesn't change the bolt tension.

I made my own spacer on a lathe, as I didn't know that there was a stock one like this, but now we all do.

Your parts may all be there, and be correct, now that I look at what you have and the drawing. Of course you are always best to check the chain line to be sure a previous owner didn't do something foolish.

Cheers, Phil
