Thanks for the great advice again Terry . For me this was very timely as I developed the leak on the weekend and was going to take the easy option to attempt cleaning the seal . I guess I will reassess that plan and replace the seal
They can be made to work really well. I am not disturbed about single spring forks. They have been around for many years now and not proven to be detrimental
Question: When you turn down a lower tube and knock the imperfections off with 400/800 grit paper, doesn't that create micro ridges on the chrome that will grind away at the inside of the fork seals?
They are as you say "Micro Ridges" and in between those ridges sits a film of oil which, as you are no doubt aware is non compressible. This allows the seal lip to glide over the ridges rather than drop down in between them. Its benefits have been well studied and proven. The effect is very similar to cylinder honing. It in fact promotes seal life rather than hamper it....but I understand your doubt here as it doesn't sound immediately logical.
any thoughts on the green SKF seals? I've switched to using those on WP forks because I feel they hold up a little better in our wet muddy conditions. Placebo effect?
I find the SKFs a little better for friction and reasonable for seal life. NOK seals (KYB Showa) are a little better for durability but not quite as slippery....really, there's not much in it.
Bad. As Terry pointed out in the video you do no want dirt and grit being dragged up and down your forks as your suspension works! Same thing as putting sand paper under your windshield wiper and turning them on.
Those rubber gaiters used on conventional fork are great, manufacturers have used them for years. The neoprene ones they sell for upside down forks are what Terry doesn't like. I have a close friend that has used the neoprene type on his 2013 YZF250 from new and he never had any issues till today. I personal don't use them.
This information is invaluable. Thank you!
You're very welcome!
Great video Terry, very well done.
Cheers...Thanks Adam

Best wishes to you and all you care for
@@justadam1917 Thanks Adam....I hope you are keeping well
Well made as always, thank you! Can you please make a short video on how you buff the tubes?
That will be done today and hopefully up tonight
Informative vid🙏.
(Btw Terry, keen to hear your initial thoughts on the new betas employing the zf single spring forks)

Thanks Terry. I learn a ton from your videos and appreciate you spreading your wealth of knowledge out to the masses

So, would fork gaiters be a good or bad thing?

95% of us would be better served with conventional forks. Better seal life, better compliance. But they don't look cool like a male slider.
