K1 easy way to change the spur

[RickRick]

Ok what's the best way to change the spur, just done a rebuild and changed to RW spur but can't see a way other than taking everything round there to bits

I just remove the top deck, undo the 2 screws from underneath off the alloy bit closest to the spur (not the side u adjust the slipper) then undoing the nut from the layshaft the spur just comes out. Has been a while since I changed it but don't think I've missed any steps
