I was browsing another forum, and ran across a list of fork diameters

Nice find...  Bookmarked for future use!

You swap the whole front end. Not just the triple.
Also you cant toss in legs from a different bike into your katana triple cos diameters are not the only thing. Leg spacing, axle size, wheel width, caliper bolts and disk diameter all play a huge part. You the whole front end off the donor bike. The one small advantage of a katana is that we know it uses the same wheel as GS, that is it. Even on a katana you use kat brakes, kat axle, kat triples ... sorta like the blues brothers going cop motor, cop brakes, cop suspension, cop seats, cop roof, cop tires, cop doors, cop lights, cop paint, cop floor, cop horn ....
Cool.

So what your saying buddah is that you must swap the whole front end of the donor bike instead of swapping in katana triples and then putting any forks that fit in them because the forks might spaced differently then designed.  Couldnt you use the kat spacers because, theoretically, the forks should be spaced the same as the kats

even if you did that your still looking at bearing diameters axle diameters axle length  caliper alignment  just to name a few things

That is true only if ... same axle diameter and there is the kicker ... same caliper bolt pattern and offset ... and same disk.

You put kawi legs in the kat triple, OK they will bolt up, but kawi wheel has 6 bolt disks that are flat.
If you fit a kat wheel in it, it may need a bearing swap if kawi axle is different, now that the wheel is in, you have to offset the disk from the kat wheel into the caliper, use the kawi caliper if the kawi disc is the same dia.
If you fit kawi wheel in it, you have to get spacers to fit it, then the disk will fit no problems, but your caliper may need to be moved or the disk may need to be moved to mate. If you're putting legs wheel and calipers form 1 bike, you might as well get the stem and triple from it too.
If you're mixing and matching more than just 2 bikes, you're on your own ... just remember in case you need to replace stuff, you're gonna be in trouble.

Ahh ok got it.  From all that it just sounds easier to swap everything together, forks and all. (unless the front rim is hella more expensive than what you already got   )

Well ... we use the GS rim cos the kat rim is the same ... is it the best damn thing under the sun ... hell no, not even close ... but its a huge upgrade beyond which costs out weigh the benifits and its almost a direct bolt on.
Cool.
