If your motorcycle has conventional upside down forks (Rebound Adjusters in both fork caps where they sit in the center of the Preload Adjusters), do both Rebound Adjusters have the same number of clicks or turns available? If not, here's how to fix the problem with Triumph 675 Street Triple R forks as an example. - Sport
Thanks Dave, had a gixer1000 k3 with a similar issue from previous home bodgers. I sorted it, and nice to see I done it right after seeing your excellent vids. Stay safe 🇬🇧
First!! And thanks for sharing all you’re great knowledge! I am much more confident in my motorcycle bc of you! Hope to meet you one day!
Nice vid. Thank you for posting!
You can find the owners manual PDF for any bike online.
Great video, really helped get my rebound adjusters correct. Do you have a video to fix problems with my preload adjusters?? Thanks for this and everything you do!!
I do not have a fork cap complete disassembly video. Normally preload adjusters get stuck from metal debris inside the cap.
Dave, any preference on fork oil brands? Any that you find slicker than others? Thanks for the videos. I keep learning.
This video saved me. After a shop bodged a pump and dump oil change on my forks, (hydrolocked them!), I took it upon myself do fix them. Yamaha specified 12mm of thread gap for the fork cap bolt to screw into, but when I did that, 1 fork had 16 clicks of rebound and the other only 6 clicks. I followed Dave's video to set both forks up with matching clicks. My question is....what caused this rebound mismatch between the fork legs in the 1st place? In my case, the forks are fairly low mileage, but a couple of years ago I had straight rate race tech springs (and spacers) installed....
The cause was the cap and jam nut being tightened without changing the position of the adjuster so it was "free". Common error unfortunately and hats off for you fixing it yourself!
Just as I was jokingly thinking "nah let's put some loctite on it!!" Old mate piped up hahahaha!!
Is there a piece of this video missing? Right after the 'full range' of 30 clicks clockwise from full out is determined, it appears that Dave screws the rebound clockwise another 17 clicks before reassembly. Did Dave take the 30 clicks back out before adding back the 17 clicks clockwise? What I am asking is, just before reassembly was the rebound at 17 clicks from full out? And do these 675 shocks give two clicks per full rotation of the rebound?
There are 4 clicks per 360 degrees. I wanted to see the maximum number of clicks available = 30. I reset the cap to 17 clicks in from all the way counter clockwise to keep the stock setting.
@@CatalystReactionSBW Thank you for clarifying, that makes sense. Do you have any videos that explain how these damping adjustments work mechanically? 'Full clockwise' means maximum damping, which I assume means the little valve or orifice at the other end is fully closed. What opens them back up as the adjustment is turned counter clockwise? Is there a spring at the bottom or is it hydraulic pressure? Apologies for all the questions. Your videos are exceptionally clear and we learn so much from them.
@@ke9g Valving is static and installed therefore oil flow is pressure based. With COM/TEN it is dynamic restriction based on oil flow via a tapered needle. I have a video on valving, but I do not have a video on compression needles.
Was wondering the same thing, my 08 cbr600rr has the same problem, as long as I follow this procedure, my pre load and compression adj. Should be ok right? Dave is a must subscribe!
@@dezdez4885 Once the cap is off, setting rebound at 2.5 to 3 turns from minimum is easy. Take time on the cap install.
@dave Just curious, what if 1 fork has its rebound or damping screw that goes 0.5 or 1 turn more than the other fork? Is it necessary to correct it or can we just let it be as long as the number of clicks on both sides are in sync?
Start all the way left, then count in so keep the screws even. As long as the rebound screws match and control rebound, all is well. If you max one screw, then it needs fixing.
Thank you for the video. I somehow missed the point when should I do this procedure?
It's if the full amount of clicks or turns are different from 1 leg to the other
You should do it if you have 2 rebound adjusters and the count for each one is different.
I have a Super Duke 2020 1290 and please clarify the term (turn ) as to what/// A complete circle as 1...?
360 degrees = 1 turn
My right fork on R1 2006, rebound fork moves freely after installation. There is no click.
Hi Dave,
I'm Pavel from the Czech Republic, this video helped me a lot. When I bought my street triple 675, manufactured in 2013, every fork was different and I didn't know what I was doing.
Now I wanted to set the SAG according to one of your videos, but I can't. I wanted a more aggressive setting = 33mm front fork and 30mm rear shock. I have adjusted the rear shock, but the front forks are at maximum preload and have 38mm of sag (my weight is 92kg with gear) Is it possible that the springs are from the factory for a lighter rider? I couldn't find the original length of the springs in the Street triple manual to measure if the springs are tired.
Fully extended fork is 130mm to dust seal.
The oil level in the fork is the same as in the manual = 89mm.
Can you please advise me how to solve this?
Thank you very much Pavel
Hello Pavel;. Thank you for your comment. Yes, stock springs are softer on older versions so sag at 38 as a maximum number is not unusual. With maximum preload and compression are you using 100% of the available fork travel?
@@CatalystReactionSBW Thank you for your replay... I sended message with video on your Facebook messenger.
Left uneven wouldn't that only dictate your softest settings staying even?
If you have two rebound adjusters on the fork caps, they must be even in range and position. If rebound is in one leg and compression int he other they can be even or uneven.
On my Zx10r, Kawasaki actually has a depth spec to screw the cap on that I needed to measure with some calipers. This depth was NOT the natural stopping point of the fork cap down the threads (could have been threaded down further). Is that unusual?
Same on my ZX14, I didn't measure the first fork and ended up with a full turn less adjustment. Had to pull apart and reset the cap to the correct depth.
Hey. My wife is not able to flat foot her bike. You have a video on how to lower the bike by an half inch?
Set preload as soft as it will go, then if compression is present, set that as soft as it will go. See how here feet are now. Forks can be moved slightly to lower the front as well.
@@CatalystReactionSBW Thank you.
Hi Dave, If you have Rebound on the left fork and Compression on the right fork, can you adjust the Compression adjusters the same way as the Rebound adjusters? Cheers Fred
Single function forks will be at different numbers. They balance each other out like counterweights. Those adjusters adjust the same in both cases.
@@CatalystReactionSBW So the inside of both forks (rebound and compression) looks the same if you remove the top cap?
@@fredh4641 Inside these forks will look the same:- cap, spacer, spring, road, cartridge. For big piston forks you will see cap, rod and large allen fitting with spring below it and no cartridge inside.
I’ve got an 05 zx10r left fork cap has 23 clicks? The right Reboud adjuster has 17 clicks. I don’t see any tool marks on the caps. I don’t believe they have ever been broke apart if they have I can’t tell. Why els would this happen?
If they have never been apart, then this would have come that way from the manufacturer (KYB) as an assembly inconsistency. Very, very rare but I've seen it before.
how does a half turn count as one....I counted 8 full 360 turns... as 1 what am I missing is 30 turns( 1/2 turns) and only 15 ...?? help what I am saying is one full turn ( all the way around start to finish ! ) Right ??!!
