O K captpfd,
on your 15V650, the adjuster points kinda down and forward. You want it more horizontal and perpendicular. Don't use the little 90 degree piece that comes with the kit. On my 15V650, it clears the shock spring and doesn't foul the rear line. I can't post a pic, my wife has the family camera.
Speedy makes some nice stuff, but I didn't follow instructions exactly. Same with lowering the front and the kickstand mod.
