Volume of fork oil needed per fork for a 1986 VF 400 nc 13

The capacity for a fork is usually per leg.

hi could you be a little more descriptive with your request, pleas tell me have you completely dismantled the forks etc, i will try get back to you asap

Google motorcycle salvage honda and see what you can find.

Buy some measuring cups up to about 13oz ...before you start on the first fork, release air pressure then take out drain bolt and let it fill up, then pump the fork up and down to squirt out the last little bit.... you"ll get a ball park figure this way. I use ten weight oil and it seems fine, oh and you dont have to buy the expensive stuff from the dealer, any transmission fluid will work.. if you decide to fill it with air be very careful if your using a gas station hose..just give it a little squirt then check. I put in about 5 psi too much and you might blow a seal. Another thing...if its never been changed before you'll find the drain bolts hard to remove..i used an allen with small extension tube to give it more leverage.
