| Yup its 30mm, I know that from painful experience as it's 2mm smaller than the clutch centre nut !!. Have to agree with Jools comment about machining away the front face of the socket for better engagement on the narrow nut, something I've been suggesting for ages. It really does help and I've done all my wheel nut sockets for 9*6/748, MV and ST.
Being a smart ass I took both front and rear wheel nut sockets when we did our ride down to Spain recently. Clutch centre nut came loose for no apparent reason while we were in the middle of nowhere and I smugly thought that one of the wheel nut sockets was bound to fit. Nope, both too small.
Another tip when you put the wheel back in is to check alignment independent of the marks on the swinging arm plates, they are often twisted and it makes a difference to the ride and chain wear if it all lines up spot on. We always had to do this when we was boys as there weren't fancy adjusters on our old Brit bikes. |
