Well, fitting the shock was straight forward.
Rather than modifying the shock top "eye" We made two press fit inserts to fit in the frame. This serves two porposes. It sleeves the Fazer mount holes and provides fixed spacers for the shock. You then simply use a standard R6 bolt (or a bolt that fits) and don't have to change anything. If you need to replace the shock, simply remove and fit the new one. If you want to go back to a fazer shock, remove, push out the sleeves and fit.
Here are the inserts.
This shows one pressed into the fazer frame top shock mount hole:
This is the "inside" of the top shock mount. So you can see the shoulder part which is the required spacer for the narrower R6 shock mount, and the inner sleeve that goes all the way through to the outer side of the mount wall.
This pic shows how the spacers fit when .... fitted. So one each side, they butt up to the shock mount, the bolt going through the lot and the sleeves go through the frame mount hole (one per side). Snug fit.
Of course the shock is shorter than the fazer, so you need the dog bones (130mm for std height). I think the shortest bones you could put on are 124mm before the shock spring starts to touch the swingarm. I made mine 128mm which jacks it up a touch.
The shock itself requires no modifications when fitting this way. It also needs no grinding at the top like I believe the older shocks do. The spring that comes on it is stiffer than the Fazer but I had a stiffer one to put on so fitted that to mine.
Rides superbly!!
Currently these shocks are cheap, I got mine for less than £100 on eBay, zero miles. They have proper threaded preload adjusters etc, a pretty decent shock. I made some adustments to the comp/rebound and it makes a noticable difference unlike some...
