I WILL COWER ALL MEASSUREMENTS IN DETAILS WHEN I HAVE DONE A TECHNICAL DRAWING,
THIS IS MY WORK AND IF YOU FOLLOW IT - YOU ARE ON YOUR OWN RISK !!
I HAVE DONE THIS IN MY GARAGE - USING MY KNOWLEDGE - I'M WORKING WITH THE EMERGENCY AGENCY AND IS NOT A CERTIFIED MECHANICH/ENGINEER
(if I needed to state this to our friendly americans)
CB1000R swingarm is approx 1,5-2cm longer
have the same spacing (more or less) in the front
with only minor modifications fits directly into/around the frame
rear brake master is positioned as the CB1000R.
space around and inside is equal to the 900/919 swingarm leaving the stock exhaust routing the needed room.
you might have to consider which rearwheel to use - I didnt like the CB1000R four spoke design, opted for a VFR800 wheel that have an extra extrudetion (?) inside on the surface thats faces the wheel pickup - I donno if all VFR wheels have this or not?
This will raise the rear end with approx 2,5cm when used with the CB1000R shock
CB1000R shock is longer than the CB900, but the pivot point is further back - away from the top pivot of the shock leaving only a slight raise (actually wanted in my case)
you need to trim down the bushing on the right hand side so its flush with the swingarm as there is only 0,5-1mm in total of slack framewith and swingarm-inner. No 10 on this drawing
Right hand side is fixed by the bearing and I didnt do anything else on this side.
Left hand side you will have to remove from the inner part of the foot-peg console, where the swingarm axel goes through. I did it with a saw and finished it with a metal file, 5mm off
I trimmed down the No 11 bushing by approx 5mm, note this bushing is the free moving part in the axel assembly that will make the swingarm fixed on side to side movement. so when you tighten the swingarm axel you will have to fabricate some spacers to make the foot-peg-console fit to the upper and lower mountings - when you mount this the first time you will see some spacing/slack between the console and frame on these points, meassure and make spacers.
now the CB1000R or 900 swingarmaxel will fit in lenght as it would be to short if this wasnt done. (they are identical)
Next is that the shock is angled a bit more back leaving a clearange issue with the expansion container, but as this is PPHD its possible to form it thermaly using cauting and a heatgun (?) as the temperature around 150 c is enought to press it into another shape (with something round'y) leaving space for the shock. I did remove a rubber collar around the top of the shock as I didnt see any use for it anyway.
the chain alignment should now be spot on, but the CB1000R OEM chain is one link to short, either you will have to add one link or put in a completely new one.
connect brakeline (I will make a different routing or make a small heatshield)
put decent rubber on the rearwheel
