crappy stock shocks

hi all. i feel like a Alien,being from the UK that is. lol. im wondering if anyone can tell me if its possible to bin my stock shocks because they have always been rubbish,,and replace them with shocks from a 1990 harley 1200cc sportster. i know where a set of these shocks are,,but do not know the eye to eye measurements of them etc. also would you suspect they may be a little worn because of their age ?. many thanks.

Note KM`s post #2 for info on Sportster shocks.

ie. any Sportster shock 11 1/2" - 12 1/2" long "eye to eye" should work.

The only problem is.....Harleys ride worse then our 750s.

Are the shocks leaking fluid or have you checked the air pressure in the shocks. I run around 20psi or lower at the #2 setting and it rides fine on these pot hole laden roads here in Maine. I up the pressure if i have a passenger and set on #3 or #4.

Thanks. i put air in them,around 35psi,and i've tried lower. they must have an air leak because when i re-check them a day or two later they are back to zero. i have them set on 4,,and with a passenger on they ground out on any form of pot hole. im just looking for a cheaper option then buying new.

Stupid question here... How do you put air in the shocks? And where do you check the pressure?

Never even thought about having to do that...

There is an air valve on the top of the shock, just above the damper adjustment collar, that looks just like the valve on the tire.
The black plastic cap is just a little bigger than on the tire, and sticks out horizontally from the mount by the eye.

A fork shock pump with a zero loss gauge is the best way to inflate and check pressure. 0-43 psi working range.
A bicycle hand pump can be substituted.
DO NOT USE A GARAGE AIR COMPRESSOR HOSE. Too much volume will wreck the shock.

They would still work. If you set the preload for a sag of a whole inch, you'd be at 12-1/2....which is stock.
