brent and tim asked for some more details of my 38mm FrankenFront, so here you go
the fork legs are off a late 80s gpz600, think it was called ninja600r in USA. mine had antidive only in one leg, some have on both.
they are pretty light, lighter than the honda stock 35mm and have modern features like double teflon bushings. I blocked off the antidive and removed from the bottom of the tubes the one way valves that acted on the simple tube dampers.
inside these, i placed a rare set of new (!) late 90s cbr900 cartridges which have adjustable damping. found them in a swap market for 50 euro still in their original honda cartons...
in the legs i didnt do much other than turning off on the lathe a plethora of ears sticking out that had no use.
Another thing i did was to replace the super heavy steel tube caps with aluminum ones with the same thread.
Last, i shortened the springs to get my preffered 0.9kg/mm rate and turned nylon spacers to compensate.
I wanted some really light triples without the expense of CNC0ing my own. ended up with 1st gen ZX6R triples that have a neat double bolt fixing in the bottom one as well as an aluminum stem. cant find the numbers but i think that triples alone were more than 1kg less than the honda's.
as these are for a 41mm tube, turned some 41-38 spacers to hold them. more work on the lathe was to adapt the tapered set of honda ID size bearing to the OD of the stem. form the top triple i sawed off the ignition cyl bracket.
last, the stock dust cup above the top bearing wouldnt work, so turned one form nylon to fit.
Yes, quite some hours spent on the lathe, but love working on it!
Not sure the fork bridge is really necessary but at least it keeps the fron fender above the wheel
