Honda ST1300 Rear Suspension Pre-load Adjuster Maintenance
Vložit

- Over time the hydraulic fluid in the Honda ST1300 Pan European rear suspension pre-load preload adjuster will seep out and result in poor handling. The fix is to add more fluid and remove the air. Its really simple and requires little time and few tools. The standard position for the rear suspension preload adjuster is 7 clicks in. I currently run mine somewhere between 4 and 6 clicks in. The STANDARD Rebound Damping adjustment on the other side is to match up the two dots (one turn out from full clockwise) I run mine slightly Softer when biking solo at 190#. Use your own weight and riding style to determine where the adjustments for rebound damping (dampener) and spring pre-load (preloader).
Been trying to find a video for ages describing this problem with the preload adjuster. My VFR800 runs a very similar setup, and has the same problem. Now it’s seems you’ve solved it! Many thanks for the video 👍
You're welcome.. Glad to help.
Just in case anybody comes across this, my VFR800 VTEC 6th Gen had the same problem, squishy rear end and even with the remote preload adjust turned all the way up, I never had enough preload to take a pillion.
Did this repair and now it works a treat, big thumbs up 👍
Thank you for your time. Currently working on mine. I did not push the plunger back down. I hope that is why I am getting zero tension right now.. 30 mins later: Success. That was the problem. Have tension now and a much better feel to suspension. Thank you.
Jody Hodge I’m glad it helped now go ride it!
Thanks, now I better go check mine...Cheers for that..
@@colinlockett1529 thanks for the comment. Get it ready to ride!
Thanks very much for this video, very simple step by step instructions for the job. Did mine today and its made such a difference. Thanks again. Ride safe 😁
Yep. It’s one of those things you don’t know is broke until you fix it. Thanks for the comment!
You are the man, just did mine,next to zero oil in the reservoir, thanks.❤
Your welcome. Now you know!
Thanks! This thing was a mystery. Great clear easy to follow.
Glad you liked it!
That was a really useful video for servicing the pre-load adjuster and also explaining the rebound adjustment. Thanks.
Thank you and good luck with yours
хвала на вашем видео пуно сте ми помогли поздрав из Србије
Glad to help!
Thanks for the video. I did this on my ST today and it went just as you illustrated.
Glad it helped!
Excellent instructional vid! Thank you!
I have two pans and I have never fiddled with that control
time to try!
Thank you. It’s very easy to do.
Another great instructional video . This will be very helpful for another ST owner with a pre-load adjustment problem.
The service manual wants it to replaced but it isn't necessary at all.
i just done it , and its really easy to adjust correctly now
thanks mate
hub air no problem. Glad it helped you!
@@JustPlainCommonSense Thanks to you from many ST 1300 owners, because i share your vidéo on a French St 1300 facebook group , and many peoples have the same problem
Best regards mate ;)
Thanks for the good advice
Any time!
Thanks for sharing informations about this problem mate ;)
I have same problem, so i will solve by myself with your help

Bonjour! Glad I could help. It is a super easy repair.
Great video! Just bought a used 2004 ST1300 and restored the preload functionality following your instructions. Talked to the local Honda dealer about the issue to try and figure out what oil to use but they insisted that the shock and the preload adjuster “came as a kit” and that they had never heard of anyone refilling the adjuster and that it wasn’t advised.
Anyway thanks for the instructional video, really awesome!
The process isn't in the factory manual so they will not recommend it. Floor jack oil is hydraulic oil and works fine.
Just Plain Common Sense
Ok thanks! I used fork oil hope that will work as well. :O
There's no chance I can put the thing in its center stand by myself. Lol I've tried a dozen or more times but damm it's heavy!! Thanks for the video!!
You can do it! It’s a technique; not strength.
Well thought out and presented. Thanks for posting.
Glad it helped.
Well done, thank you
Thank you for taking the time to comment.
Great video.
Thank you. I was just thinking of this video today
Thanks for your help..ST's Rock!!!
You’re welcome. Enjoy the ride!
This video is a fantastic help to me. Thank you for making it!
You’re welcome! Enjoy the new ride!
Another great video. Just bought my ST and going to do this cause my preload screws almost in before catching
It’s really easy and makes a big difference in the ride. Good luck!
Awesome! Makes me want a bike again!
You have the room to park it and time to ride it. What are you waiting on??
Great video... what a piece of cake thanks to you.
Glad to help. Man, what a name!!🤣
@@JustPlainCommonSense well I’m campaigning for Joe Biden so I thought it fit…thanks
Super - thanks
Thanks for the comment!
Nicely laid back and easily understood video. Two suggestions, why not use fork oil (weight info must be on net?), pour oil in carefully (use a clear tube?) without dripping it in to stop air bubbles being introduced. Thanks for the video
I wouldn’t doubt it if fork oil and Jack oil are the same.
Doing this today...thank you!
You got this!
fantastic! Great video! Checked my ST
and went ahead and fixed her up! Thanks again
Glad it helped!
Great knowledge of st1300 pan European!! Keep up the videos
Thank you very much!!
Thanks for the info. Great detail and very informative. Merry xmas
Glad to help Merry Christmas!
Excellent vid, thanks!
Glad you liked it!
Nicely done. Should be a breeze to complete this task.
It is Super simple!
Interessant information, thanks for uploading! I like it.
.
Great tips many thanks, gonna do mine now
You will likely see a vast difference. I have been backing my preload off lately to give be a softer ride.
Yep. Small world. I was searching the you niverse for a video on the dampening screw on my Honda stateline shock.
And I just watched your video. Totally different systems but I liked the air chisel idea you came up with!
Very elegantly done vid, thank you!
You’re welcome!
@@JustPlainCommonSense ...so, it was love at first sight the year Honda released the first ST-1100 in that same "graceful red" and all these years later I am at a junction in life where the consummation of that lust could be realized this Spring. Just watched your filter change and gotta say, thanks again for these tutorials (aside from being rathwr intense foreplay) your presentation truly is exceptional!
@@swainsongable I just traded mine in on an Indian Roadmaster. New Love!
@@JustPlainCommonSense Sounds exciting! Such a completely different personality ;)
Whoever inherits your ST will get a good deal regardless what they pay for her.
Thats Great thank Yu for video
Thank you for the comment.
Great instructional video. What oil did you use ?
I showed it early in the video.
I changed mine , by just removing two bolts 🔩 on back of the preload adjuster, then pull lightly and it will allow enough slack , remove banjo bolt from back and then used carb cleaner flooded the end filling reservoir then shake n dump , fill area where ball for click is with carb cleaner, then dump , all clean , click working nice fill with a spray top off of a olf wax polish bottle and , replace on bike 🏍 took 15 min.. never took off seat, side panels or adjuster screw.
You should do a video of that. Thanks for sharing
Great Video, simple and to the point!! :)
Thanks Chris. Glad you liked it and thanks for the comment!
@@JustPlainCommonSense I just brought an ST1300 and will pick it up this week. Any Advice on the Preload and Damper settings for single and two riding?
Thanks for the great and reassuring video. Did this yesterday afternoon and must admit it all went just as you described. I got some hydraulic oil from our local farm supplies store, 46 grade was their recommendation based on their knowledge of other Honda equipment. Big change to handling as well. Many thanks
I’m glad it worked out so well! You should be able to gauge when a refill is due by how the adjustment knob feels. Enjoy the new ride!
Whoo whee! I hope there won’t be a test on it. I’m still at the coloring a picture of a motorcycle level. 🥺 You sure are handy.😊
I'm waiting for a passenger so I can test it out hehehe
Excellent! Thanks for the share.
It’s easy. Thanks for the comment
Great video sir. Just did mine and too lazy to go to store but had some 15WT fork oil. Did this process with that oil. Hope it's not too thick but can always run her out to "soft" I reckon.
Good luck with that. It calls for hydraulic oil such as fork or Jack oil but you might be okay
It will be fine. The oil just preloads the spring. The viscosity matters most when used in a damping situation, being forced through a small orifice. The thicker stuff will flow through the tube with no problem. I used 20wt because I was hoping it would stay put.
I'm doing this service this weekend. Right now mine goes in 16 turns before any pressure
Your system is basically dry!
@@JustPlainCommonSense just did the service and it now makes tension at two clicks. I'm running my dampening screw 1.5 turns from the hard setting. 205lb rider, so I'll try that. Preload is set at the standard mark on the adjuster
@@todd5052 I’m glad it worked out!
Thanks very much for this video. One question, what fluid did you use to refill?
I should have shown that in the video or in the video description but I think it is hydraulic Jack fluid. Available from any auto parts store. Good luck!
Yep. Literally 23 seconds into the video I tell you the secret fluid.
@@JustPlainCommonSense My apologies. I didn't find it. Thank You.
What type of seat do you have on your ST in this video. It looks very comfortable.
That is a Corbin. I’ve had them on other bikes and actually have one arriving today for my Royal Enfield. I highly recommend them.
Great video. Do you know the dimension of the copper crush washer (I guess we should put some new one each time)? Thank you
I don't know. I typically use those copper crush washers several times with great results.
The crush washers will seal better when new. I have to pick some up so I can do it again. Mine lasted about two years. I used 20wt fork oil, but your choice did the same for less cost. I hoped the viscosity would make it stay put in the system.
@@alanhassall you can regenerate (anneal) the old copper washer with a simple process.heat it till it glows red and drop it into cold water. It swells back to its original thickness. Only copper!
How do you know when the fluid needs to be changed other than just taking it out via these steps?
There isn’t a periodic change as I recall. It just weeps out from use and will have to be replaced
@@JustPlainCommonSense gotcha. I only usually ride by myself. I have a 2009 ST1300PA that I got a little more than a year ago with about 44k miles and now have got 50k on it. The guy before me took good care of it so I was just curious. I'm still learning much about the bike, and it's only me riding it, even with a two-seater installed. I'm just about to upload a short video with it now
What is the product information on that top case base?
I'm not sure. I sold that bike some time ago.
Hello! I watched your video and I'm interested in what oil you poured into the regulator? Greeting.
Hydraulic pump oil
hi what oil did zou use there is it dot4 scar fluid
Hydraulic jack oil. Its available at the auto parts store.
any tips on lowering bike
My best tip is Don’t Do It. It changes the handling and Corning abilities. Buy a bike that fits your frame instead.
More specifically, what is the exact brand and name of the fluid you used on your bike?
I showed what I used 23 seconds into the video
It was so quick. But yeah I just realized that.
I serviced the front forks on my ST 1300 and used the oil I had left over, Honda Pro ss 10weight
@@bernieswonger4780 sounds right
What's the BEST fluid to use?
Hydraulic Jack oil
What type/weight of oil did you use?
It’s in the video. Jack oil
i am new to this hydraulic / oil stuff, what prompted you to use JACK OIL? thanks and respectfully.
