fork oil level ??

david, true,i'm running mine @ 100mm ahhhhhhhhh the plushness...........jimbo

what is the fork oil level for yz400f 99` ?

i think in the book it is 130mm max but

somebody told me that it can be even 100mm max...

is that tru ???


A high fork oil level (a low number) means the fork will progressively get firmer as it moves further into the stroke. Aka, more bottoming resistance.

A cheap form of medical insurance when learning how to jump.

However, more oil also means the front end will not dive as much when entering a corner. The bike will push or seem top heavy. Not a good thing.

As always, it's a compromise.


My forks were done at MX-Tech and set at 95mm, works great with their valving. mike
