Mick, that nut is a bugger to get off, do you have a friend with a hammer/rattle gun thing ? Dont do what i did and snap off one of the iner bolt mount things on the basket? if you can find one there aroun £30 - 40 to replace! get the proper clutch tool or stuff some wrags in there to stop it from moving. as for oil, i must confess i just went to my honda dealer and asked what to stick in, i think it was Motul light gear oil????? ...
