Default Easy way of changing fork oil?

     

Well... I have graduated to the bikes with the inverted forks. Yes... I am old school and changing the fork oil back in the day was a breeze. Is there an easy way or a short cut to just simply changing the fork oil without having to take appart half the fork???

I'm riding now a 96 CR250. Thanks for the input.

Mike

They have to come off the bike at a minimum. Before you pull them, loosen the top triple clamps and then break the fork caps free. Once you have them off, you should be able to unscrew the caps, slide the fork tubes down a little, then turn them upside down and dump out the old oil without taking anything else apart. You'll want to put in a litte fresh oil and pump the forks a few times to help get out old contaminated oil.
But ideally you should disassemble them as the valving is very sensitive to the debris that builds up over time.
Be glad you don't have a 97 and up, they have two separate oil chambers and you do have to take them further apart to replace the oil in both.

I believe I saw a few "how to's " floating around here somewhere. Do a quick search. This is something you want to do the right way, and take your time!

Carlcr...

Yes in your case your forks should be conventional cartridge type so you should be able to just open them up and put a little more in.

thanks

To speed up this task,drain old oil, get one of those metal tire valve caps with built in air valve driver,remove air bleed screw on cr,get a 50cc type needle syringe from a co-op/livestock like store and add new fork oil via
syringe through there instead of fighting handler bars/removing big nuts.

You can short cut it, But I recommend pulling them down and cleaning the tubes in a parts washer to get any contaminates out. With that being said if you don't have a manual the fluid height is 90mm. You should need 2 quarts of 5wt fluid .

Old thread.
Do not care anymore on old threads, it's not fair for those of us that have only joined up months ago that come across old threads of interest but never got to particpate in some of these 130+pages of threads..
