Where is a good place to order the fork boots/seals for the 38mm ceriani forks? I looked online and most suppliers are in the UK. I also need a left hand fork slider. The bike has dual disks. I believe I can fix mine, but would like a better one. Thanks Cheers Brian

Standard are two 38x50x7mm seals each side, readily available. Many use instead a single twin lip 38x50x10.5(or 12) that were used in many Japanese dirt bikes and are also available, either with a small spacer under it or as I do, just inserted in enough rot the circle to fit above it.
I saw somewhere that had new rubber covers (boots?) for the top of the sliders but can't find the link to them, do some searching.
Sliders are not very easy to find second hand, just keep searching on the net.

I think Vince installed some special low friction seals, might have been more expensive than standard but with good results?

cheers,

SKF do super low friction ones - fitted them to the Kayaba USD 41mm fully adjustables. Probably not worth the expense unless you have teflon low-stiction bushings. They were about 3, 4, 5??? times the price of a std seal. Can't remember exactly
 
They are expensive, I cannot remember if it was $100 or $200 for both forks. That includes some high tech mud scrapers that took some machining of these scrapers to fit. Q you are probably right as too only making a big difference when your fork has actual bushes instead of wearing on the alloy bottom legs themselves. I was looking under every option at the time to reduce sticktion. I tend to go to extremes but that's my fun to be had. I eventually found a place in Melbourne that does Hard Anodising as that's what is supposed to have to biggest effect on reducing sticktion. Had the Pantah forks done and when I finally put the carbs back on I might find out how that goes as well. It's got the SBK seals as well.
 
No criticism intended Vince. We all willingly spend dough on our bikes seeking improvements - part of the fun of modifying I reckon!

I'm sure there are ways of incorporating teflon seals into old forks, even if it means creating new sliders (which I think has been done already, IIRC, for early Ducati and Marzo sliders - not cheap!!). And then there are the complete 'classic' fork packages like the Hungarian (?) ones, about which I'm yet to read reports (Todd!!).
 
Thanks for all the helpful suggestions. I was able to order and receive a slider from Wolgang. You are correct, He is a really nice fellow and has lots of parts. I also got the seals and dust covers. It will be together quite quickly. Just in time for it to be too cold to ride. I live at 7000 ft! Cheers Brian
