Rear shock

[Byrdman]

Has anyone ever cut apart a 919 rear shock?

I am building a fully custom rear shock from my 919 dual sport using parts from; a ST1300 shock, a GL1800 shock, and the 919 shock.

I'm considering using the oil reservoir from the 919 shock on the GL1800 shock but I want to know what's up in the top chamber before I get crazy.

are you asking what's inside a remote reservoir? isn't much there , a nitrogen bladder and oil

[Byrdman]

No, at the very top of the 919 shock. Is there just oil in the last half inch, is there additional valving that meters oil to and from the reservoir.

I think I may have to cut one up.............

No need to cut it up -- once the bottom out cushion seat is tapped out of the shock body the rod bushing / seal carrier can be removed by pushing it down into the shock tube far enough to clear the retaining ring, carefully removing the ring, and slide hammer the lower eye / shock rod / damper assy out. Obviously the shock must be depressurized before doing this unless you want the flying pieces embedded in your forehead.

I'm willing to bet there isn't anything other than the drilling for the flex hose inside the shock, but never having had one apart before ...

Do you have any experience with shocks? I'm just asking because arranging the damper disc springs is a bit of a black art, and the probability of getting it close enough to right on the first try without a lot of experience is pretty low.

In any case good luck with this.
