good question on the shock. I came up with this set up years ago on a mock up in my shop but never tried it. I measured all points from my stock swingarm. linkage points and shock position. I then installed the 06 swinger and had to make adjustments on the linkage arms to be functional. all appeard to be in workable order I posted this information on .net I remember a member took it to the next level and did the swap over he posted a video and he also replied he had owned several r's in the past and that this was a smoother ride. this will be my first try at it. so lets hope it works in all aspects. if I fail at it then I go back to the drawing board.
