Saw that pix once & asked about it years ago ...still no luck.

One thing to watch out for is early yokes don't go with 850 frames, might get into issues with engine/tranny /swingarm/center stand - cradle diffs.

New use for a Kibblewhite Performance valve spring (2013)

Getting ready for my upcoming 4-5000 mile road trip and thought I would play with reducing vibration on the road. The iso rubbers were replace a couple years ago but with heavy 880 pistons and steel rods the bike has never been as smooth as it was originally. Now after a couple years the...

If you want to post directly become a VIP member. Otherwise use an external hosting service. I like Google drive personally, as the pictures can be enlarged easily.

To share a folder, "Right click" on it then choose "Sharing" and in the subsequent window click "Change"

Basically a stock honda model swingarm modded to mount up to the stock cradle, then also single shock. There's also lots of other info on a single shock setup tho tons of pix are gone now

- edit: forgot about this part but it does say for a fat tire

"The entire motor and drive train with isolastics was moved 1" to the left to accommodate the tire"

Trick suspension

Here's Tyler's smooth riding Norton with modern VFR 750 monoshock rear suspension and fat tire. The entire motor and drive train with isolastics was moved 1" to the left to accommodate the tire. Front end is off a CRB900 Keihin CRS carbs tucked away underneath the tank.
