You dont need to drill out the rivets!Just use a pointed object and a small hammer to push them in the centre and the middle bit will fall out.Then use pointed pliers to pull them out.Simple!

When you come to install the rear fenders DO NOT use the expanding rivets as instructed in the kit on the bottom hole,just use a normal push in rivet that comes in the RB kit.This way you wont need to remove the rear wheels.
