If you don't get an error message, then check your email account for an activation message. If you get a message stating that the email address is already in use, then your account still exists so follow the instructions in the forum FAQ for resetting your password.

    Have you forgotten your password or have a new email address? Then read the forum FAQ for details on how to reset it.

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
 
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? :-k

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. :encouragement:

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.
