If you are happy with the way that it rides, putting heavier in will make it harsh. It is better to raise the oil level a little at a time to combat bottoming. With more oil you have a smaller air space, less air space more PSI at the top of the stroke. Don't go past the max limit though or your seals will tell you!

On the KX fork I found that it is virtually impossible to get both great bottoming resistance AND smooth operation, without a revalve. I found that increasing the oil level was not the right thing to do. An increased level lead to mid-stroke hashness, very noticeable. The best fix was to run a lower than normal oil level and use heavier springs. This made a super-smooth fork that only bottomed on the worse stuff. I never did revalve it. Cam.

i'm 250lbs 6'1 and was blowing fork seals,tried factory seals,aftermarket and everything,they all blew.went w/ stiffer race tech springs and little thicker oil and havent bottomed out or blown a seal in 3 yrs.didnt revalve but a good idea,over filling is bad idea.
