Fork Seal Service (Showa BPF) ZX10R | CBR1000RR

[@MattFellowswasHere]

This might be the BEST and most explanatory MC component tear-down/re-build video I have EVER seen on KZbin. Can't believe there are only 1400-ish views. Clearly the dude has some sort of engineering or mechanical background and has an innate sense of what the parts actually DO... As far as the torque on that splined compression tube being too hot from the factory he's DEAD-ON-ACCURATE...there's no reason on God's earth they should ever spin something down into micro-threading that hard...it's a recipe for disaster...and no mechanical or environmental forces that would EVER cause it to spin loose during use...the best!!

[@TheMotorcycleBoss]

Matt Fellows i really appreciate your comment. My goal this video was to ensure it was as clear as possible. And from your comment, i was able to accomplish that. I hope the rest of my videos are able to help you out as well. I look forward to hearing from you in future vids. Thanks bro.

I've done a lot of fork seals but would have been lost on these forks without this video so my hats off to you, best U tube instructional video I have ever seen!!

[@alishaperkins]

My name is Charles. I'm using my wife's computer to know how to change my fork seals. This is the most dead on tutorial of this sort of tedious work I've ever seen. (I like Batman too lol). I really enjoyed every bit of this video. I give you much props my guy. Thanks for sharing this with the world to view. I will be performing this task once my seals are ordered.

[@TheMotorcycleBoss]

Awesome! I really appreciate that you took out the time to tell me what you think Charles and I thank you for it. I wanted to make this info free to the masses since there was only a paid for video and another one with not much explanation or lighting. So I set out to make the best comprehensive vid I can about this mystifying subject. I'm glad to know that my videos are helping people and if I can make you guys learn, save money and smile while doing it, then I did my job and gave back to the KZbin community. I really hope your project goes well. (Takes forever so free up an afternoon and order some pizza and beer if you drink) Because we all know that nothing really gets fixed unless you have a drink in one hand and a wrench in the other. Cheers bro! I'm here if you need me.

[@metakmoto]

@@TheMotorcycleBoss The Motorcycle Boss I just finished the project and everything went smooth thanks to your video. I did notice my forks were a bit stiffer than usual. I did watch another video and the measuring process was different in that videos. The guy measured the fluid after he put the piston and cylinder back in. What are your thoughts?

[@TheMotorcycleBoss]

@@metakmoto Your Dream Is Reality Hey! Im glad your project went well. I felt the same thing when I did mine and all I had to do was adjust my compression and rebound screws on top of the forks. What I noticed is that because you have old fluid, heat-cycled, full of particulates, etc. The overall viscosity of the oil has changed and we become used to it. When we add new fluid, like in my video, I used Honda oil instead of Showa. Although they maybe manufactured to similar specs, the materials used, thresholds, tolerances, and other factors in the manufacturing process can potentially change small characteristics in the oil although I doubt much if any of that is even noticable to the rider. So new oil may feel slightly different because you got used to the characteristics of the old oil. Regarding the piston being inside the assembly before checking the oil level; I don't know where people tend to find this info because many people have commented asking the same thing. Put simply, in the factory service manual, it specifically states what needs to be present inside the fork tube before checking the oil level. Even Dave Moss' video shows this. You can check the oil level with the piston assembly and cylinder sleeve installed but you will want to take note of the oil level before you begin the disassembly then fill it back up to the same point. I hope this was able to free up any confusion you may have had. I'm glad your project went smoothly. I would recommend adjusting your top screws to where you are happy and you should be fine from there. Thanks for taking the time to comment and I look forward to hearing from you in the future. Cheers!

[@erichneumann9760]

Both Kawasaki and Suzuki Manual(for bikes with this Showa BPF) indicate to measure oil level after having installed the piston rod guide and the piston rod assembly itself. I've heard that it should be done without the piston assembly, like you did in the video. The oil level won't be the same, I guess?

[@TheMotorcycleBoss]

I understand your concern. I have had people in the past have the same question. However, the factory service manual I have for my bike says nothing regarding the piston assembly being present when adding oil. If the piston assembly was added first then yes your oil level will be different. But no. You are not supposed to add the piston assembly before adding oil. Im 100% certain. In case you are curious, it says to add approximately 420mL (14.2 US oz) of fork oil per leg. After disassembly and completely dry: 495 + or - 2.5 mL. I hope this helps

[@EVil-ob8in]

Ive replaced the fork seals on a 2008 R6 13S. In some ways the R6 was trickier as you you need a tool that screws into a rod preventing it from sinking ino the fork tube. I found the job impossible despite improvisation, accepted defeat and bought the tool to proceed with the job. Anyway, this seems a little easier than the R6 but I'll definitely refer back to your video if I need to replace fork seals on my Gen 4 ZX10R. Liked and Subscribed.

[@TheMotorcycleBoss]

@EVil-ob8in that threaded rod tool for those forks is pretty vital. I did the same thing on my first set. Trying to do it without the tool seems difficult. The only way I can see it maybe working is if you force a rubber hose on the end and use that to lift it up. Thanks for the sub. Much appreciated!

Hello again. I happened to service my BPF's about a month ago and your video was my go to guide. It all went smoothly as i felt like I've done this thing before! A tip to anyone who may try. I didn't have the golden racetech tool so I welded together two 27mm nuts and made it happen. After i was done,I welded an extra 34mm nut on top of this new tool so as to make it easier to grab on to it while you are trying to thread it in. So basically an improved version of the tool at the cost of maybe 2€.

[@peterpuetzfeld1187]

Very good video. Mr.Boss, t that helped me a lot to replace the seals of my CBR100RR 2017 SC77 Honda forks. But I found a major difference according to the official Honda workshop manual. Honda recommends to measure the oil level (84 mm) after installation of inner parts, big piston, spring, damping rod etc. With your method the air chamber might be to small leading to a very progressive suspension afterwards, because inserting the parts into the oil filled fork afterwards lets the oil level rise significantly

[@TheMotorcycleBoss]

Thanks for your comment! If you happen to have gone through some of the other comments on this video, this difference has already been addressed. In the ZX10R factory service manual, the oil level is checked as shown in this video. This rebuild method also aligns with Dave Moss' video tutorial on these as well. I spoke to Showa themselves regarding this and they confirmed the order specified in this video. However; manufacturers such as Honda may recommend a different method & specs; which is fine. Always follow the order specified by your factory service manual. Aside from that detail, the disassembly and reassembly are the same regardless of manufacturer. I hope this helps!

[@DL180sx]

Correct me if I'm wrong but the service manual shows to check the Fork Fluid level AFTER the Rod guide case (the threaded part that's done up to 90nm originally) is seated and torqued. IF this is the case it might explain why it felt a little off when you rode it as you set the fluid way too high if it was done without that being installed as shown.

[@TheMotorcycleBoss]

Service manual indicates to measure the oil level as you say. However; I was following Dave Moss' video on this where he does it prior as shown in this video. The reason the forks felt a little off was because they were leaking and I had less oil than I should've before this install and I got used to it. All I needed to do was adjust my compression screw and it went back to normal. Been years riding with them like this and absolutely zero issues.

[@DL180sx]

@@TheMotorcycleBoss That makes sense that the fork level was adjusted to compensate for the removal of said parts. That information would be harder to find than the service manual. I "think" and i could be wrong but the service manual calls for 84mm vs RACETECHs suggested 115mm and this would probably be the reason why even though its not clearly stated.

Great video but I have to question just leaving the fork to sit after oil fill. Every suspension I've seen or worked with slides the outer up and down slowly to bleed all the air out. Letting it sit will not necessarily encourage air to move to the surface.

By far the easiest to understand and most clear motorcycle component tear down video I’ve seen. Clearly your very knowledgeable about the components and tools your working with. Awesome work mate. One question though, you said if only doing an oil change you could drain the oil (and I assume refill) without taking out the piston rod assembly... How do you measure the oil air gap if you haven’t taken it out?

[@TheMotorcycleBoss]

Thanks a lot. You want to measure the height of the oil first, then drain. When you fill it back up, you just get it to match the same level as before that you measured.

[@Beaver314]

why do you measure the fluid before everything is in there? other videos ive seen, everything is already assembled, shock tube and everything before they measure the correct fluid level. all that's left is to screw on the cap. That might be the cause of your stiff feeling after the test ride. because if you measure the level and then assemble the remaining parts, the oil level will have risen meaning you've put too much in.

[@TheMotorcycleBoss]

I've received multiple comments like this. 100% when you check the fluid level in these forks, you do it without the damper as indicated in the factory service manual. You can fill the oil level with everything installed but you have to know what the oil level is supposed to be with all parts assembled which most service manuals do not include that spec because they aren't supposed to be filled that way. The reason my suspension felt weird was because that bike is my daily driver and any time you get old fluid and swap it out with new fluid, you will feel a difference. So simply my settings were tuned for the old oil. I just had to turn some screws for the new oil.

[@marcusbarnes5929]

Great tutorial well done...just one question, Do you measure oil level before adding the internals or after adding the internals? Some videos show measuring oil levels with internals installed.

[@TheMotorcycleBoss]

Thanks! I appreciate it. I've had this question a few times before in the comments. Idk why other people believe that you need to check the oil level with the damper assembly inserted but this is false. Both the factory service manual as well as Dave Moss' paid video that covers the rebuild process for these forks, it clearly indicates to not have the internals inserted. Immediately after finishing installing the bushings, oil seal & dust seal; fill with oil. The only way you can rebuild these forks with the internals when you fill with oil is if you already know what the air gap is supposed to be with the internals in. The air gap level you are given is without internals. Just keep in mind that your suspension may feel slightly different than before simply due to fresh oil in the system. So be ready to tweak your rebound and compression. I hope this clears things up and I hope I've earned your sub if I haven't yet. Good luck with your project! I'm here if you have any questions. Ride safe! Cheers!

[@marcusbarnes5929]

@@TheMotorcycleBoss definitely subscribed man. Did you have to back off any of the adjusters before disassembly ? Yeh Dave moss is a guru of suspension too. I have read the manual also and that's why I wonder why some measure oil level with internals in ?? They would have less oil dampening they should. Lol

[@TheMotorcycleBoss]

@@marcusbarnes5929 Thanks for subbing! I appreciate it! I don't know why people include the internals. If it clearly shows the steps in the manual alone, then why do people put them in? Makes no sense to me lol. Regarding the adjusters, no. One of the advantages of the BPF fork system is that rebound and compression adjustment height stays the same during the rebuild process. The adjustment is internal rather than external. In short, as long as you don't move the adjuster screws in the fork cap, and when you screw the fork cap back on all the way until it bottoms out, your adjustments will remain exactly the same. There is simply a small plate that presses down on the rods to force the valves in the damper open or closed. So as long as the height adjuster screws are not touched then your adjustments will remain untouched as well. I hope this was a good enough explanation for you. Thanks for your comment!

[@zxr4700]

Great video, and thank for putting in all that time too help all of us out there.! Although I have too correct you. When you measure the oil level, you do it without the cartridge and the cylinder in the fork. As I can see from the manual it has too be in there before you set the level I couldn’t get the oil milliliters too fit with oil level , until I found out about the cartridge.. Quite a important thing!! Please correct me if I am wrong?! Best regards

[@TheMotorcycleBoss]

The fork oil level is actually supposed to be measured without the piston and the cylinder. However; if you are only doing a fork oil service and dont have the tool to remove the cylinder, you can measure the level before draining the fork. Then you will know what level to get it back to. But the specification for oil level is never with the dampener assembly inside. Otherwise you run the possibility of overfilling. I hope this helps you. Thanks for the support.

Does a breaker bar in the axle hole damage the axle hole? Do you step it up with a closer fit spacer, then bar through the spacer?im getting ready to attempt my first fork seal fix but this is my holdup. A lot of force there on the loosenup part. Top vids

There should be no issue using a breaker bar against it but wrapping a towel or rag around the breaker bar should work just fine. It'll take a lot more force to severely damage the fork in that manner. I hope your project goes well!

Если не лень будет переводить мой текст, все таки уровень неправильно измерен. Инструкция устроена таким образом,что по ней нужно идти шаг за шагом.и хоть это не написано конкретно, но момент проверки уровня указан уже после того, как предлагается собрать все до момента, когда останется закрутить верхнюю крышку с регулировками жёсткости. И даже на иллюстрации видно, что при проверке уровня, трубку шприца опускают именно в элемент, который затягивается с усилием 90 нм. Я тоже недавно менял масло и сделал как на видео. А теперь при просмотре видео мне стало интересно и я почитал инструкцию более внимательно. И да, в ней проверка уровня масла выполняется после сборки. Если выполнять сборку шаг за шагом. Хоть прямым текстом этого и не написано. Мне стоит снять амортизатор и убрать лишнее масло

Suspension might have felt a little off because you did not check the oil level (air gap) correctly you're supposed to check the level with the rod guide case and the dampening rod installed into the fork

[@TheMotorcycleBoss]

No. The air gap was checked correctly. The damping rod and rod guide are not supposed to be installed when checking air gap. However, if you know the oil level after they are installed you can check it then. But it will take a very long time to do that because the damping rod and guide have such a small tolerance. My suspension felt off because i had new oil and not the old oil anymore. I just adjusted the rebound and compression and years later, still perfect suspension.

Great video! But a quick question. Did you miss out to fit the following parts between the cylinder and fork cap? BUSHING-FRONT FORK 44065-0040 RING-O 92055-0215

[@TheMotorcycleBoss]

Hey! Thanks for your comment. I never removed either of those parts from the fork components so they were still there during assembly. It is good practice to replace o-rings when you are in a position to do so but I felt that they weren't needing replacement. Regarding the bushing, you can see that it is still attatched to the cylinder I remove with the racetech tool. I never removed that bushing as it didn't need to be removed to install new fork seals. I hope this clears things up! Thanks for your support and I appreciate you taking time to comment. Ride safe. Cheers!

[@timjamesvella]

Hi mate. What diameter PVC tube did you use?

[@TheMotorcycleBoss]

Tim Vella good question. Honestly, idk. All i did was measure the diameter of the chrome tube then go to home depot and try to find a close match. Don't remember the specific diameter tho.

[@timjamesvella]

The Motorcycle Boss thanks mate. I had my forks serviced and resprung 10months ago and they started leaking . OEM lasted 7 years and 19,000kms. I saw you didn't use a vice. I don't have one either. So was thinking of undoing the rod guide case with the fork in the bike to make it easier. Thoughts?

[@TheMotorcycleBoss]

Tim Vella isnt a bad idea. Except that you have to be sure you have the clearance to do it above the forks. And you would have to do both at the same time in order for you to compress the forks enough to get to the cylinder. Really up to you. I would only crack it loose then remove it completely with the fork out of the bike. As long as you have a decent sized rod to go through the lower fork axle clamp, and a breaker bar, removing the cylinder out of the bike should be a piece of cake. Lmk how it goes tho

[@fastshapes3dsigns290]

Great video 👍🏼

[@Well_Rounded]

Thank you

[@TheMotorcycleBoss]

Bo problem. I hope it was helpful!

[@HighGrade_FireBlade]

A way better method than using tape is cutting a strip of plastic from a plastic milk jug so that it rolls up and makes a cylinder. Position the plastic cylinder on the top of the fork tube and slide the seal on the plastic just like with a seal bullet. Once the seal is on the fork tube with the plastic protecting it on the inside you can slide the seal down past the bushing channel. To make it easier, put some greasy on the inside of the makeshift seal bullet so it slides with ease. I used to use tape as well but after being shown this method I don’t think I’d go back.

[@TheMotorcycleBoss]

Yes. I am aware of that method as well. If you take a look at my latest fork video, I switched to using a simple sandwich bag and it seems to be a bit easier than the milk jug method in my opinion. Plus I always have sandwich bags and don't always have an empty milk jug or water bottle around. And I don't want to keep a scrap like that in my toolbox. I also see the sandwich bag as being much softer on the seal as far as edges are concerned which can further reduce the risk of slicing up the seal during installation and removal. I hope you give that method a try some time and tell me what you think. In any case, thanks for commenting and I really appreciate you taking the time to watch my video. I hope it was helpful.
