XV750SE rear shock absorber pressure?

[Chris N Deuchar]

Hi, this is on my 1981 Yamaha - which in the service manual says on
page 5-36 that the air pressure in the (single large) rear shock
should be 4 bar (57 psi). In the diagram on page 7-62 it says 1 bar
(14 psi) in the 'standard aire' position on the remote adjuster.

Now I have no remote adjuster - just a filler valve dangling near the
swing arm. Presumably the remote adjuster died and was removed!

So, how much air pressure should there be in the shock?

TIA

All the bikes I've had with air-assisted rear shocks have had a minimum
pressure recommendation, which IIRC was about 1 bar. I'd say use whatever
works best for you, within reason.

On my '81 XV920RH (monoshock Euro model) I ran between 30 and 55 psi,
depending on load packed. I normally ran 35 psi.
