Great video guys, is there any way you could elaborate on the threaded bar tool, how to make it? Big thanks

Zachary Fleming says:

Best video ever. Thank you guys so much for this. Keep the the awesome work.

Aldebaran Star says:

Excellent video, thank you.

Hello. Do you know if is it possible to change the fork oil of GS500 96′ model without removing the forks from the bike. I saw on that video that there is a bolt on the bottom of the fork, may be it will work only by removing the wheel.

Wilfredo Gutierrez says:

Hello,

I want to know if the head of the piston is 5/8s or 14mm. Can anyone answer that ?

Alex Cail says:

Im not sure how it works beyond that sorry.

sicnukka says:

Thanks Alex! That makes sense. Is this also a way of adjusting the stiffness in the shocks, by increasing or decreasing the air gap? I’m guessing a smaller air gap would increase the stiffness, correct?

Alex Cail says:

yes the air gap is basically a way of measuring how much fork oil is in the fork. so if there is only 91mm of air space then there is a certain amount of oil in the fork.

sicnukka says:

Very thorough instructions. I’m new to working on motorcycles, so I’m not 100% sure about certain things. I was curious about “setting the air gap” What exactly is that measurement? Is it the space between the oil and the top of the inner tube?

Draknareth says:

This was really helpful, i’ve just noticed one of the seals on my GSF650 has started leaking so i’ll be taking that apart at the weekend I guess 😛

dewsy86 says:

Why not loosen the Alan bolt first? That way you won’t need to make a tool for when you take the top off, it should all come out as one

crgrob says:

5.37: is that the damper rod seat you are setting in place?

sempron46 says:

For a 96 Suzuki Banidt 600, a 3/4″-10 thread rod and nuts did the trick.

ThunderWindz says:

i just cant get that bottom bolt out. any tips?

crzydood17 says:

its a 1.5 inch Inside Diameter on the PVC pipe and the bolt itself is 5/8ths the nuts are going to be 15/16ths or 7/8ths or whatever size nut fits on a 5/8ths OD threaded rod.

Kulrajdyr says:

how to remove bolt from the piston??, I’ve got K4 F model

hrm29 says:

hi BaltimoreGS,

Great video, but i have a couple questions about the “custom” tools. what size threaded rod did you use? you say in the video it’s 5/8″ rob but it looks bigger. Also you said the PVC pipe is 1/2″ and again, it does not look like 1/2″. It may just be an optical illusion but some clarification would be great, thanks.

Does the fork seal spring go up are down

zbychs says:

Thanks for the video! It’s very informative.

I’ve tried it on Suzuki Bandit GSF 400 1995. The “special tool” for this model has to have a 28 mm nut at the end (approximately). I used a 30 mm nut (M20) and grinded it to 28 mm.

scotthere9 says:

Is it the same procedure for a 1980 GS1000 with air forks?

BaltimoreGS says:

Never worked on a GN400 so I don’t know if the tool will work. I also don’t know the air gap but you could measure the fluid instead. Factory fill was 241mL of 15w oil according to a google search.

billybullfrog says:

I’m going to attempt this on a 81 gn400, would the air gap be the same 91mm? And would that homemade tool work as well? Thanks Tom

Jose Gutierrez says:

Nice video!

Cole Isaacs says:

Thanks for posting this, I’ll attempt to do this as I can’t stand the stock springs anymore >:(.

BaltimoreGS says:

Spring down on a single spring seal.

BaltimoreGS says:

No problem, glad it helped you! I can’t take credit for the tool though, that was devised by another gstwin.com forum member.

xena4747 says:

springs down diz!! if you go spring up you would have a real hard time seating your seal. i know, i tried it!

xena4747 says:

thanks for making a video that shows how to change your seals like a regular person. seems like most of the other how to videos aren’t clear in the steps, have bad audio, use tools the average person doesn’t have & blahblahblah. and the tool you made for holding the dampening rod in place, i think it may have saved my life! and for only 6 bucks. your tutorial is excellent. thanks!!!!!

Dizzzledan says:

When you install the fork oil seals, does the spring side go up or down? Mine are down, so I’m thinking it doesn’t matter?
