GAS PRESSURE

Post by LKey »

Hi all,
I have a 1987 FZR400 SP.
Does anybody know the correct gas pressure for the rear shock reservoir?
Thanks

they suggested about 200psi, but when you check similar bikes it might be less. Honda's VFR400 manual states 142psi

Try somebody else if you don't trust them.
How about looking for a similar unit on a Yamaha - maybe OW01 and the YZF750 SP. Honda might use a different suspension manufacturer for their shocks and so have a different pressure.

I have the workshop supplement for that model.

There does not appear to be a pressure listed for the remote.

(Mind the manual is very hard to decipher unless one can read Japanese $%*~#>< characters.)

They are really high, My friend used to rebuild them and always used to put about 200 in everything!

Thank you all for your input.
We put in 200psi and it works fine
