The answers to your questions are found in this nice write up here: Fork oil change
Hi, new to this forum and the NC700. Been riding KLR's for a while.
What is the proper fork oil level (cc and distance). Weight of fork oil?
For the reply
Short cut - OEM is Honda SS-47 and the level is 104 mm. I would consider Honda SS-8 as well.
SAE weight is not very precise measurement of flow in light oils used in forks and shocks so it should only be used when comparing "weights" within one brand. One brands 7wt could act "thicker" than another brand of 10wt.
Interesting that Racetech's number is so far off. Their web site says to use 120mm. Maybe that's due to different springs, or the emulators, or something.
SAE grade means absolutely, positively _nothing_ in fork oil. You must look at the 40C (100F) viscosity in cSt (SUS) to compare fork oils.
Hey guys, I'm new to the Forum and hope I'm posting this message in the correct place.
I'd love to know if anyone has had success replacing "just" the fork oil with a different viscosity and achieved a noticeable improvement? I know there's many great threads on major fork mods, but I'd like to start with the easiest and least expensive and see if I'm happy.
With damping rod forks, changing the oil weight generally gains something at the expense of something else.
If you go thicker you'll have less brake dive, but it'll be harsher over bumps.
So would the opposite be true... a thinner viscosity oil providing more brake drive and a smoother suspension response over pumps.
I definitely won't be experimenting with this. Just curious if anyone has found an oil that they believe works better than the stock oil.
