hi, using 150 rear wheel and 530 chain on z1000j, will i need to use a offset sprocket, or could i use a small spacer
behind sprocket, as not that much wider, will have to get sprocket nut off first as someone has tack welded nut to sprocket!!!, what size is sprocket nut ? thanks richard

If you mean 'Nut' it is 27mm AF.
You can probably put up to about 2mm of spacer behind the sprocket. After that, there is not enough of the spline part of the shaft available for the splined washer to bite on.
