80 1100ex fork capacity

[Guest]

I am trying to swap out my fork oil for some fresh 15w and I have a clymer here that said 5.6oz. I put 5.6oz each, filled it up it 25 psi and now I see another page that says 8.0oz

Does anyone know which is correct?
Thank you

You can download a real Suzuki factory service manual for your bike here...http://members.dslextreme.com/users/bikecliff/

The info is more reliable than Clymers.

I just did one of my '81 1100E's a couple of months ago. 8.0 ounces in each leg. 8.3 if it is the L model. I filled each of mine to (8.1 ounces each.)

I always go by the level method. My bike is 7.7" from the top, spring removed, compressed. It takes the guesswork out of it. I always wondered how much was still clinging to the measuring cup, left inside the forks.....etc.

And whatever your oil amount (or level), 25 psi is WAY too much air in the forks.

While you have them apart, why not put some new springs in there?

Progressives are available from Z1 for about $75, Sonic springs are available from Sonic for about $85.

Either one will do a LOT better than your worn-out stock springs and they will require NO additional air.

Thanks guys I removed the forks from the bike, completely drained and added the 8.

Steve, it's funny you say 25 psi is too much. The clymer says Suzuki recommends 25 and no more than 35.

I've used clymer on all my Vintage suzukis.. maybe that's a mistake!

Didn't really seem to hold the air pressure any how. Had only about 5 pounds left after 6 hours.

Are you saying the progressive springs from z1 won't require air any air pressure?

If so I will probably purchase, I would rather not hassle with maintaining the pressure. Too many bikes that need to many things!

Thanks again.

I have the Sonic .95/kg straight rate springs in my 80 Gs1100E forks with 8.1oz of 20w fork oil. No air pressure needed period.
