2021 KYB need to check oil level
« on: October 15, 2021, 09:23:57 AM »
How do I check the oil level in the forks? Got the ICS springs replaced a couple of months ago but just want to double check how much oil is in each leg. I know 345ml is what the manual calls for, back when I bought the bike removed 20ml and it improved a lot but stupid me forgot to tell the guy who replaced the ICS springs about the oil level so he probably topped it off at what the manual says.

I guess no one wants to answer your question. I don't know if there is a spec for oil level.  Just the amount of fork oil that is standard when you refill them.  Take them apart and change the oil in the outer tube and then you will know it's right.

Thanks, no big deal I found a nice video on youtube on how to service KYB forks.

I have taken forks off and dumped out a few CC of oil before.  I was considering doing same on my new 2022 as I have had good results on other forks running a few CC less or more than manual calls for. Just depends on what part of the stroke you are wanting to change. On one bike (09 200 XC with closed chamber forks) I actually had to go the other way. Raised oil level a bit and softened the clickers. Other bikes I have dropped the oil and stiffened the clickers. I had read somewhere that there is a possibility the 22's may have had an incorrect fork oil fill at delivery. I should check this anyway before indicting a performance characteristic. Either way I think a lighter oil is the way to go for slow speed work. Use at your own risk-

I just removed the cap but did not remove damper rod springs and "stuff". Just took off cap and poured some out.
