I had made my own bronze, extended top bushes, so these were cut back in length and bored out to accept a Teflon bush I spun up myself, I left a seat in the bottom and installed a thin washer at the top over the flanged section of the bush, to locate the bush. I inserted the Teflon into the bronze when it was still solid, then drilled and bored the interior to mate up with the 34.5mm forks. The section is pretty thin, but it is well located in the bush, so we will see how it lives. The sliding effect is very good, even with twisted side load it glides, unlike standard sintered bronze. I performed a similar trick on the bottom bush to locate a thin Teflon outer over the original floating bush. Geez the forks feel like those modern bikes now. Also I did the trick with the Honda fit fork seals, one other Forum member wrote about, they are 35mm internal and very slightly larger in od, about .3 of a mm. I made up a little seal holder out of nylon that allowed me to mount the seal in the lathe, without damaging the seal and skimmed off the od to make a nice fit in the Norton slider. These seals certainly slide nicer than original seals.
Well, report back on riding experience after tomorrow's run
Glad to hear you like the Honda seals. i've been using them for a long-long time now since the mid 80's. I just use some 80 grit on the od to get them to fit.
I also pack the recess area of the seal with silicone grease for lubrication---the stuff BMW used on the early K-bike steering head. I have never had a seal problem
with these. I also use gaiters to protect the fork seal swept area.
