82xj650maxim/air adjustable forks

my bike has sit for almost 2years and there is no air in the forks i dont know how much needed?

 

The air is not needed in the forks. It will only make the seals start to leak faster. I was told this by the dealer himself. I never put any air in mine after changing seals and it handles just fine.

 

ok sounds good thanks

 

Here's what the Yamaha people say:

NOTE:
When checking and adjustment the air pressure, there should be no weight on the font end of the motorcycle.

 

If you do add air to the forks, DON'T use an air compressor. Use a small hand pump (like the one for a bicycle) or you will over inflate the forks and wreck the seal.

 

For twenty--five--thousand-dollars ... and the right to come-back, next-week ...

IF you did want to goose-up the front-end of a 1983 XJ750 Maxim with a few PSI for a long, long day of InterState Highway riding ...

After you have unscrewed the plastic covers off the top of your forks to expose the air valves ...

How do you get ANY PUMP's filler-end chuck between the handlebar and air valve???

 

All that's needed is the correct tool-





BTW- the OP's bike doesn't have air forks, so you can all quit trying to suggest how much air pressure to have in his forks.

The correct answer to his question is zero psi.

Huh?

 

I wonder what the air valves on the tops of my XJ650J forks do then? :cry:

 

OK then...'81 and early '82 650 Maxims didn't have them. Your bike is either a later version, or has had an aftermarket set installed.

No matter either way: air-pressurized forks are an idea that disappeared as soon as people realized they were, at best, a crutch for front suspension tuning.

To the OP- run a few psi in your fork and don't sweat it. Better yet, install the correct rate springs and don't rely on air at all.
