From Fatblokeonbandit, on the old site:
right here we go then, This is for gsxr 750/1100 slingshot forks into a mk1 1200, 600 are the same Im told but as I have never done a 600 Ill stick to what I have. and make sure you have the forks that match the yokes...
First strip everything off of the front , wheel forks clocks headlight and the tank to save scratches, remove the yokes, take loads of pictures to aid re-assembly, I left the bars attatched with cables and hoses, except the brake hoses as im changing them for braided..
Now you can see the difference between the bandit stem and the slingshot one,

Right heres the bit you need some special tools for, or go to an engineering company with a hydraulic press. Put the yoke in and press out the stem , our one at work is a ten tonne press and it made a right crack when it freed off, don’t think you can do it with a hammer, you cant ……..
Do the same with the other yoke…
here are the stems removed
If you can leave the stem out, now is the time to remove the lock stops and drill and fit new ones, If you havent a press or done want to pay twice for and engineering firm to do it, have the stem refitted,
Or if you have the facilities, mill off the stops, or use a hacksaw and file if the stem is already in…
Then either offer the stem up to the frame and mark the position of the new lock stops or measure the position from the bandit yoke and mark the postion on the slingy one.
drill and tap the holes to 8mm, using a pillar drill or do it with a hand held drill if the stem is in, being very careful to get it vertical.
Now install the bearing..put the bottom yoke and stem in the freezer for a couple of hours and the bearing, after you have degreased it, in the oven for 30 mins at 150 degrees, When ready slip the bearing on and tap it down evenly only hitting the race,,, simple…
now you can fit the bottom yoke……..
if you have nt already fitted the stem now is the time to do it, here I cam across a problem, the stem I was using I have had in a drawer for ages, I bought it as a 1200 stem, but it turns out its from an early 600…. Bugger, some of the the 600 stems ( dont know what years ) for some reason are 0.1mm smaller in diameter in the part that fits the bottom yoke,,,, Arse, Plan B,, stick it in me lathes and knurl the bottom part this increases the diameter to make it areally tight fit, and in it goes using the press again,,,,
now fit the bottom yoke….
Right the top yoke next, I am using the risers from the bandit, but the bolts are way tooo long and have a small head and aren’t standard, I will use 10mm allen bolts but the heads wont go in the riser… off to the lathe again to make them fit, if you are using other types or risers its probably easier….but I’m tight..
mark out and drill 2 x 10 mm holes, the underneath is not flat so you need to either make some plates or large washers to spread the loads under the nut or if you have a pillar drill and an end milling cutter remove the web so its flat..
roght bolt it all together, I used a couple of spacers to lift the bars clear of the fork adjusters, depends on your riser height,,, with the ignition switch, 2 small spacers are needed as the mounting point is different to the banditone…fit top yoke..
fit forks and tighten up..
