My forks are leaking so I did a bit of searching but couldn't find any decent videos. Thought I'd search for ones that Spicy110 has done and he just happened to have posted this video an hour ago... Looking forward to the fork seal replacement video. Great videos spicy, I've been riding about 2 years now and your videos really helped me learn how to ride properly in the early days. I've also learnt loads about how bikes work from your videos too. Thanks for all the help.
Thanks the bike gods for your channel. I swear I spend a lot of time looking on the internet for random answers to random questions. I find nothing. Yet all your videos answer these problems I have 🤔
Ive not serviced forks for 5 years and this video was great just to get my head back into it. Thanks for a very well made video on the topic. Fork seals have gone on my ktm390 so il need to service the forks and get new brakes.....so maybe it is good to keep on top of it.
Very good explanation of function with all the parts laid out👍. For those who have never seen the inside of a set of forks they can be a bit of a mystery as to how they work, and I think you covered that well !!! 😃
Really awesome and interesting video Spicy, although I understand in a basic way how they work, it is really helpful to have an actual fork disassembled in front of us to see how it actually does tha magic! :-)
Took mine to a shop and they put in double the amount of recommended ml of oil lol I know cuz I drained it out ,my forks were so stiff I almost broke a wrist, watching these TH-cam videos tought me how to do it myself thanks
Careful with for oil 'weights'. There is no standard for fork oil viscosity, the W actually means "Winter". Each brand does whatever they want regarding their fork-oils. Best sticking with the brand recommendation from the manufacturer.
2yrs passed I hope you can still answer question. I replaced oil of my fork suspension, but when I drive and run into bumps, I feel like my body is hitting the bump, as if my suspension does not have oil. What could be the problem here?
I tried to repair one telescopic suspension cause it's oil seal was damaged, unfortunately it can't work as I expected, bump badly, what might be the issue here
Thank you for that that was nice I do appreciate that hopefully sometime this year I’ll be passing my theory then I’m going to go for my A license i’ll be coming up to 50 on the 17th of March. I have had a lot of things happened to me in my life all I want to do is move into a different direction in life by getting a motorbike and enjoying it in 2009 I had testicle cancer and fibrosis of my lungs in 2011 my sister passed away aged 32 and my dad and my Nan who was very close to I have some good days some bad days but watching your videos don’t help when I was younger are used to ride a scooter now I’m older and wiser I want to learn to ride a motorbike with gears so I can enjoy riding a motorbike then hopefully I can meet you sometime in the future when this is Pandemic is over it will be nice to meet the person who makes these videos thank you for making the videos I do appreciate it. And my name is Geoff not Jeoff
Thanks for this video, ive also watched the other one when u instal new seals, I bought an xj6, the prev owner said he changed the seals at a garage, and they leaks ever since. Forks looks good, any chance the seals to be bigger as in your case ? They dont look bigger but sh.t I will try get some from ebay and change them myself Great video, thanks 😊
Hard to say what the issue is, could be out-of-spec seals, could be the person who did them damaged them. You could also have scratches or pitting in the stanchions. If they look ok there is nothing to do but change the seals and hope that's the fix.
Great video and very informative. Can you make another video where u can explain on how can we increase the suspension travel by modifying certain components inside the telescopic fork. Im curious to know if making adjustments to length of spring or the damper rod can increase the travel of the suspension system. #spicy110 @spicy110
Really interesting question, honestly I can not think of a way to do that as you would need basically replace all the parts other than caps and feet. I will look into this. If I prove myself wrong I will let you know.
Thanks for taking time to make this great video , good job . Question/s: 1, I have this type of forks on my bike GPZ500s , the shiny bit , stanchion , near the high's part , of where the seal would travel to , I have a little nick . I have 10W oil in them at moment . If I was to change that to 15W oil on both of course . Would that make the seal not travel up as much , so to miss the little nick on the stanchion ? Hope that makes sense
No that will not change the length of travel plus you really should use the right weight oil for the spec of the bike. There are ways of fixing nicks in them if you look in to it.
Zero explanation how the damper rod works. And fyi, increasing or decreasing the oil level has the corresponding effect on the "air gap." It is this, which changes the resistances in the final 30 to 50mm of travel. Even at the minimum specified amount of oil, the damper rod will continue to damp throughout it's full travel.
left and right are normally the same springs, although I do know of a few that are different i.e. like the Honda Eurosport as one side leg/stanchion has anti dive, the oil levels are different for each side. Progressive springs are important to get the right way round i.e. top and bottom, the tighter coils go to the stationary end i.e. this fork would be to the top.
Hi there! Thanks for the video. On my bike there is an oil leakage through the bolt at that screws into the damper tube (at 4:14 in your video). Is it possible to loosen this bolt and change the washer (ofcourse after draining the oil) and screwing it back in? Or do I need to take my whole suspension apart? Thanks in advance, would mean a lot if someone could help me! I have a BMW f650GS from 2001 btw, but it is somewhat the same type of fork.
If it's just the crush washer that needs replacing, in theory you can just take it out and replace the washer. (As you say you will need to replace the oil but that's no bad thing. )
If your forks have no oil they would be pogo sticks, you will have little traction cornering and you will come off. if it's an uneven amount in one to the other fork leg you will get uneven wear. If it's leaking badly it might get on your brakes. The only thing you can ride on is a very slight weeping as in just a ring of oil left around the fork tube and then do not do that for long. Long short if it's leaking you need new fork seals.
@spicy110 my very big problem is that I live in Paris and no one does this work here, they all just change the fork as it's more money for them. They told me to keep riding like this until I have to pay €500 to change the whole thing. And of course I live in am appartement and I can't try myself. I think I lost a small amount and trying with seal mate is my best option. The time until I pay €500 will be longer I guess.

Very useful explanation regrading the working of each part of the front & rear suspension
Glad it was helpful!
Need to fix my fork seal, searching utube, this is the 7th video I’ve watched and the first I’ve learned anything from.👍🏽👍🏽👍🏽
That is what I like to hear! Shame I was not nearer the top 😉

Love it. This is by far most useful video i saw on this topic.
Glad it was helpful!
This video is AMAZING!!
Thanks!
Excellent! Very elaborating about the principles. Thanks alot 🙌🏽

@@spicy110 Aye mate that'd be good, soz been ill... am having to isolate after getting the symptoms last Thursday so have not been up to much.
Took mine to a shop and they put in double the amount of recommended ml of oil lol I know cuz I drained it out ,my forks were so stiff I almost broke a wrist, watching these TH-cam videos tought me how to do it myself thanks
Very informative. Step one in overcoming my fear of hydraulics.

Nice
Thanks for this video, ive also watched the other one when u instal new seals,
I bought an xj6, the prev owner said he changed the seals at a garage, and they leaks ever since. Forks looks good, any chance the seals to be bigger as in your case ? They dont look bigger but sh.t
I will try get some from ebay and change them myself
Great video, thanks 😊

@@spicy110 i hope is the mechanic issue
Will i get a softer suspension when those wholes inside the damper is increased??
No that would reduce your damping. Depending on the bike a spring kit will be available to adjust it to your liking.
for forks with "Air" input, is there still a spring or is it all air suspension? thanks
I do not know what sort of suspension you are talking about.
Great video and very informative. Can you make another video where u can explain on how can we increase the suspension travel by modifying certain components inside the telescopic fork.

Hi. My forks got movement when bike on stand and you hold bottom and push towards rear and foward. Is that bushings been worn? Any idea? Thanks
headstock bearing? If not that, if the fork move in the middle of the fork then yer sounds like the guides are worn badly.
How can i increase suspension travel
Basically you can't, travel is defined by the physical form of the forks.
Thanks for taking time to make this great video , good job .
Question/s:
1, I have this type of forks on my bike GPZ500s , the shiny bit , stanchion , near the high's part , of where the seal would travel to , I have a little nick .

The spring have no correct side?
Left to right is interchangeable, they are the same spring. Up and down in important tho as in what end is where.
left and right are normally the same springs, although I do know of a few that are different i.e. like the Honda Eurosport as one side leg/stanchion has anti dive, the oil levels are different for each side. Progressive springs are important to get the right way round i.e. top and bottom, the tighter coils go to the stationary end i.e. this fork would be to the top.
But i couldn't find videos you are mentioning here: can you provide links ?
It's been a while what video?
@@spicy110 sorry - the one where you actually disassemble and then rebuild forks again.

So, if I have an oil leak and hypothetically I lose all the oil, which I think it's impossible, I can still ride it

QUESO CREMA!!!!!!
I wonder why a car is able to do half a million miles with no recommendation to change shock oil and seals, but bikes is just 10,000 miles.
car shocks tend to be gas filled, like the rear shock on a bike.
@@jasonjason7277 Thanks. That would certainly explain it.
Cheap or older conventional forks. My 1999 g2 has them and i put 2020 ktech r1 springs in.
