Sprocket adaptor ID

What is the inner diameter of an MNR sprocket adaptor for an R1 (what OD do I have to get a socket turned down to?)

Also what size socket do I need for the nut on the R1 output shaft?

I don't know about your first question without dropping my prop off, but the answer to the second is 36mm.







Spin 'er off Well...

36mm socket with a 50mm or less OD (the sprocket adapter is 2" ID). I guy at work with a lathe will turn a couple of mm of my new socket for me.

I used a 36mm impact socket from halfords. No turning down needed.

the one I've got is 51mm OD, 0.5mm too big. Typical.

I have loose fitted the sprocket adaptor and wondered if I need the Yamaha tab washer behind the nut. It looks like it will be awkward to get the socket on. ??

I have the tab washer but the sprocket adapter takes up all the spines. I thought about having 1mm skimmed of the adapter so the washer would have something to bite to but then decided to use threadlock instead.
