If cost of fluid is a problem, there is an alternative. I just use the GM-type ATF for fork fluid as that is what Honda recommended back in the "good old days". It has a viscosity of ~7.5 and could be used to flush old stuff before adding the new expensive fork fluids by those who want the a different viscosity.

Still way better than leaving the old oil in.

What was your mileage at the time of change? Have 36k+ miles on mine and will likely do a change this spring/summer.

Tis better to be thought a fool and remain silent, than to open one's mouth and remove all doubt.

A bit over 60,000km (about 36k Miles), if I had of known it was supposed to be changed I would have done it way earlier. I've never had to change fork seals.

To be fair it's not in the maintenance schedule. Usually it just stays in there until a seal fails, then since the forks have to come out anyway the fluid just gets changed.

I successfully did what was outlined in this video, but he leaves a few steps out.
1. Only do one fork at a time, otherwise front end will go down and will be very hard to compress springs enough to put caps back on!!!!
Best solution is you need to elevate the front wheel off the ground and unload it

2. Each fork takes 11.2 oz +/- .08 oz fluid with spring removed (I used 1qt/32oz Motul 15W from Amazon)

3. I created my own syringe kit by ordering a large syringe from Amazon



Attached a 3/8" OD clear to it - used that to draw old fluid out

When I got everything I could that way, I then attached a 1/4" OD line to that and stuck it down deeper into the fork to get the rest out

4. The manual says the fluid, with forks compressed should be 5.9" from the top


Best method would probably be to remove the forks, but I wanted to try this shortcut method to see how it works.
