What size is my nut?

What size is the nut that holds the sprocket on the transmission?

[Steve]

Not sure if that nut's part number follows the pattern of other hardware on the bike, but the number is 09159-20004. On other hardware, if you look after the dash, the "20" would indicate that it is an M20.

I think its around 32mm. Can you throw some calipers to it?

I haven't pulled the cover yet but wanted to try putting on a smaller sprocket this weekend and needed to be sure I had the right size socket.

Shift lever and five bolts. Don't take no time to check.

May have to remove the left footpeg too. I remove the front bolt, loosen the back one, and swivel the footpeg back out of the way.

Not on an 82/83....pretty sure. I have one.

[chuck hahn]

i dont have anything newer than 1979. I gotta move the peg on anything i have to get the cover off. This is the basis of the thought in my reply.

Bob's right...

OK, now you're asking a different question.

It probably takes a 32mm socket, but the threads fit an M20 bolt.

Thanks guys I'll check to see if I've got a 32mm socket, if not I'll use it as an excuse to go to harbor freight.

Or, Lowe's
They have Craftsman sockets, generally in stock on big sizes for reasonable cost.

A 1-1/4" will also work.

I got my big sprocket and clutch hub sockets at orilleys.
