Man O Man. What a nightmare it is to get the R6 with Giles rear sets to switch to GP (reverse) shifting. I heard it was easy and I just needed some washers.........BS
I gave ti a try 1 day and spent 2 hours only to find out I couldnt get it to work. Gave up put it back stock.

Sat I decided I was going to make it work. 3 more hours, several trips to the hardware store and a stripped bolt later......... Tada.

What a pain in the a$$!!!! Getting the linkage arm just the right length to make asure it will shift and not get stuck in the middle was a huge ordeal. In addition I had to buy a 10mm longer screw to allow enough room to put the 8 washers I had to use to get enough space to not rub the frame. None the less I finally got it right. Shew poor me a drink at last its over!!!!!
