82 KZ 750 Clutch hub nut

The starter clutch is out on my 82 KZ 750 motor and in the process of taking out the secondary shaft to repair/replace the starter clutch. I apparently don't have the right size socket for the clutch hub nut and was hoping someone here could chime in and let me know what size socket I need to get?

Thanks.

the nut is 32mm if i remember but it is soo tight you need either an air ratchet or do as i did ,drill the nut thru on one side & split it ,use a new one.if you try to wedge the clutch or use the clutch holding tools you just end up rounding it off or slipping off & hurting yourself.its bloody tight & awkwadly positioned to get leverage with the engine insitu.
i wish you luck changing the starter clutch is easy compared to getting the damm cluch off.also replace or at least check the primary chain sprocket damper rubbers.i skimpt on mine & it clatters on idle .

Thanks for the info. Yeah, I've pulled the motor out of the bike so I don't have to hassle with crawling on the floor and having the frame in the way.

The motor is going to be a replacement for my 650 engine once I get done fixing it up.

Well I got it off. Turns out it was a 30mm nut. I don't see any damper rubbers in the case for the primary chain though.... :huh:
