previous owner last year installed new fork seals, I thought maybe this winter I would change oil in the forks, I would like to use the syringe method but I'm not quite sure on how to do it. In picture , #1 do I remove air valve cap and take needle out and fill there with oil, or do I unscrew #2 line and fill with oil there? On other side # 3 is just like #2, do I unscrew hose line #3 and fill with oil there? I checked Clymers book no help, service manual no help. Honda dealer down the road does not work on older models like mine. any help would be appreciated, thanks.

You will have to drain the old oil first, and measure in the amount of oil needed. You can't just fill her up woth oil on top of the old stuff, if thats what you are thinking.

you must inject oil direcly to each fork leg through 3 and 2 connections. the correct oil ammount is specified on your workshop manual.

so I don't even have to mess with air valve #1 only take cap off and release air pressure. my entrance point is #3 and #2, sounds simple enough, I think maybe I can do this. thanks I appreciate this. thanks

I have never done it. but im sure it will work, because if you inject the oil through the air valve it will not split 50%50 on each fork like the air does.

Here's what I learned last month on my 1100 fork oil change...

Trying to get oil into # 2 or # 3 is very difficult... you'd have to have a verygood seal on the syringe to get oil to go into forks through there... (it did'nt want to go in)

I pulled the schrader valve on # 1 & used syringe to put correct amount of ATF in...

For the left hand fork tube, I used woodworkers syringe ( used for glue ) to inject into the drain hole... messy, & I had to put finger on hole while refilling syringe... plus compensate for a little spilled while removing syringe couple times...

If one had a larger syringe, you could get it all in one shot ...

Just trying to help, hope it goes well for you :action:

The first time I changed the oil in my forks I removed the air valve. Drained the forks. Then measured the oil into a container and then into a pump type oil can. I then pumped the oil into each fork through the drain hole. Quick replacement of the bolt meant only a little oil was lost.

However doing it this way or through the air fills at the top is fraught with danger. If the forks end up over full the seals will be blown very shortly after. Ask me how I know. Therefore I suggest you remove the airhose and remove the fork caps. Then you can pull the springs, collapse the forks and measure the oil level which should be 5.5" I think.

I put new oil in through the air line fittings. Just let air and old oil out, unscrew air line fittings and put oil in through there. I used one of my wife's hair color bottles to put the oil in. The bottle comes to a sharp tip on an angle that fit right in the holes. It even has oz's marked on the side. Worked great for me. Hope this helps. Dwight
