I've bought some rearsets and I thought I'd have a crack at changing them myself... I've done the gear side, no problem. The brake side is a little trickier... I think I need to loosen the master cylinder to access one of the two main bolts that secure the rearset to the bike. One of the master cylinder bolts appears to be facing the swing arm with a very small gap. I won't get a standard Allen key in there. A stubby one might fit but I don't have one. Can I remove the bracket that the rearset attaches to, do I need a stubby Allen key or is there another way around it?
