I just wish we had a k tech facility like this and a professional guy like him to do a full service on forks, and I'll be glad to pay 300 for it, but that is just a dream,this is the first time that I knew what's inside the forks and its kind of complicated to tear it down, clean it properly, then reassemble it, it's a hard job, and I doubt anyone in my country can do what he did with the forks, for sure they can do the fork seals and change the oil but what he did is just magic, luckily I've been riding my bike for 4 years and haven't done any service to the forks, I hope the forks are still in good shape, I really enjoyed this one it was informative like every other video on your channel, keep it up.

Fifty-four minute long video … felt like 5 - truly fascinating. And now I know what is actually going on with my shocks. So, simply pouring out the oil is not adequate. The question, hence, is where can I get this done - properly and professionally. I guess I could do this myself, taking care to remove the end nut correctly. However, worth the money to have a tech with experience and integrity to do the job correctly. Great video. Not click-bait. 😅

Quick history lesson for you. Suzuki were the first manufacturer to fit cartridge forks to a production bike. 1994 RM250. Springs don't 'wear out' but they do get shorter over time and use. The oil viscosity was mentioned but the Viscosity Index is actually more important. The V I is how much the oil 'thins out' when hot and better quality oils have a higher V I . Using a thinner oil means it thins less but then re-valving will be needed if designed for a 'thicker' oil. I'm glad he mentioned that thicker oil is generally a bad idea just slowing everything down, it was a problem with customers in the early 80's and I guess just as bad 40 years on?

That was an absolute treat👍

Great video thanks. Have done a few of these myself but never with the proper tools or the operating theatre level of cleanliness! Those forks have clearly seen some love recently, with nice paint and seals that aren't rusted in place. Would be good to see how KTech deal with a proper set of crusty forks, especially the bottom bolt and getting the oil seals out.

Enjoyed this 😊 Brings back memories of the many years working in the Pneudraulic (pneumatic & hydraulic contraction) bay for fighter aircraft. So I’ve done similar to this job but on undercarriage. Lots of similarities except higher pressures and worse smell…OMG the stink when you open an Oleo (like a shock) is beyond belief. Even 16 years since doing it I can still smell it! One major difference between aircraft and cars/bike type work is we ALWAYS replace the seals regardless. Also inspection often included Non destructive testing and measuring bores/bushes etc with micrometers. I could strip, clean, inspect, rebuild and test a main undercarriage in about 3 working days. Great fun really

I should have watched this before replacing the oil seals on the 500. It went well enough but this is a treat for the observant.

I'd love to think that the mechanics in my region are this competent. Shhh! Let me dream.

By the way, don’t overlook the steering head bearings. On my 98 VFR I thought they were shot but the grease had solidified and made them feel a bit notchy. After cleaning with races with scotch-brite and re-greasing the balls plus torquing per the Honda shop manual, the forks feel great. Don’t overlook the rear brake. Mine starting locking up. I pretty much took everything apart- the rear caliper has 3 pistons and there was a bit of moisture in all the bores. With all the plumbing, it can be a bitch to bleed but it’s worth doing.

Thanks John, this one was great! K Tech tech (didn't get his name) was awesome, too.

Good video, I like the technical content. What abrasive did he use to polish the stanchion?

Best video if ever seen on the subject. So detailed! Never knew about the real internals to the piston and shims. Just saw one thing, he placed the springs back the other way around. Is there a reason for that? Thanks in advance and again thanks for the immensely detailed video!

I didn't know the VFR came with progressive springs as standard 🤔. I have to comment, he did put the spring back in the opposite way round to how it came out. I know it won't affect the operation of what it has to do but the tighter coils should be at the bottom as that is the heavier end of the spring. It keeps the weight lower in the fork, marginally so, but it does. I enjoyed watching that, thanks. Must have been a PITA having to film it with that huge camera on your shoulder though.

4:25, springs removed with tight coils at bottom - as specified on page 13-24 of the Honda workshop manual. 48:40, springs replaced with tight coils at the top?

Top man there.

Quick questions - 1. I've my rear shock leaking and got to know I can get it rebuilt. Is it recommended, given it's going to be about 50-60% of the cost of a new shock? 2. I feel front ABS gets activated a little too quickly, especially on uneven surfaces. Could the problem be with the front suspension? I don't find anything wrong with it otherwise though.

How to find good form service?

One a sightly different note: One issue I found this summer is K-tech bushes are obviously manufactured wrong, others have had the exact same experience, so K-tech need to check this out ... Bought a full service kit (Seals/bushes/oil) I serviced my 2003 FZS1000 forks, full strip & clean, no way in hell would the top bushes knock into the lower fork, I had to do some detailed measuring & discovered the bush was physically too large a diameter even with the gap compressed, bush was a good 0.75mm too big, I had to file a good 0.5mm from the gaps to get the bush within 0.25mm so it still had an interference fit, I'll not be using K-tech bushes again based upon my experience, Genuine Yamaha next time ... I also own a 5th VFR80Fi, so it's interesting to see how others do a fork strip/rebuild, 1 issue I noticed on rebuild is he installed the spring the wrong way according to a Honda shop manual ...Honda stipulate tight coils go to the bottom, personally can't see it make a jot of difference, how the feck would a spring know which up it is, all it does is compress & rebound ... Nice to know shim stacks are serviceable, I'll be pulling my shim stacks for a well deserved clean in spring 2023.

Very good video. Well informative. Just one question. Were your springs the wrong way around to start? I ask because he put them back in the other way around… Please let me know as I’m a little confused by this.

@nick4506

@@AlunChurcher now that i think of it may be its because the top is held by the triple clamp so you get less unsprung mass. the hevey end of the spring doesn't have to move as much. just an unintuitive little trick for more performance. that's just my guess. also, coil springs don't care which end you push them by.

Was going to make the same comment. Have just put new seals on my VFR, factory manual shows tight coils to the bottom in the exploded diagram though there’s no specific mention of orientation in the text which generally does point things like that out eg; the oil seal washer must be installed flat side up. Interestingly I replaced fork springs for a friend on a CB750FA last year with Hagon ones and they had a note stating expressly to install with the tight coils to the top. 🤷🏻‍♂️

My bike's shop manual also shows the tighter coil step at the top. He did install it the opposite of how it was before, but I think that's the right way. Anyway, I don't think it matters that much unless the ends have different diameters. The spring works the same; it is compressed equally from both sided. Also, if the tighter end is in the oil, it displaces more oil.

The compression damping is much better, but the rebound is not that good. The free sag is almost non-existent and there's no preload adjustment on the fork. Is there a way of knowing what springs I have, before spending money on a new set? Will progressive springs help? Thank you!

If my livelyhood was made by people comming in and having me tear apart their entire fork to clean it completely, i'd also say that "changing the oil is a waste". :) Imagine if you had to strip your ENTIRE engine down everytime you had to change oil. lol My purely subjective experience is that changing oil is fine inbetween propper teardowns.
