I did mine on the cheap but that was largely due to having a few parts at my disposal. I modified the stem by machining 11mm (IIRC) more threads on and cutting 11mm off the top - this avoids the problem of the top yoke being held higher resulting in you needing to run the forks further up the yokes lowering ride height. Machined the inserts for some R6 top yokes as you would with R1 ones ( essentially they are the same as R1 ones but only cost £25 ) and used a YZF750 bottom yoke which requires no modifications.
I seem to remember having to do some grinding to get the steering lock to line up, this may not be required with the more popular R1 top yoke installation - and of course the strenthening work on the top yoke for the fork bolts...
Modifying the stem like that means you only loose 11mm or so in front rideheight so it doesnt drop as much as a normal install (but still more than devilsyams solution with the extenders - I believe it sits 11mm lower than stock with my setup).
This was with 4XV forks using the standard wheel, brakes etc.
For this you would need R1/R6 top yoke, YZF750 bottom yoke, machining work for the std stem, top yoke spacers making and that is about it.
Ah no, I almost forgot, the YZF750 bottom yokes are for 2mm larger diam forks so I made some inserts from 1mm alloy that line the holes, you can't see them and work a treat.
It's still a fair amount of work, you certainly appreciate the cost that some ready to fit setups cost once your done. I put some pics up of my "fitment" on here somewhere.
