Cheap rear suspension upgrade

After reading this forum for a while, I did not find a budget solution to the harsh rear suspension on my '96 Adventurer. I couldn't see dropping $6-700 for a shock for an 11 year old bike so I took matters into my own hands. I shopped E-bay for a while, looking for a shock that I though would be at least close to what I needed. I purchased a rear shock from a 1994 ZX7 (with linkage!) for $10.00. It has no nitrogen reservoir but it has adjustable rebound damping and it was about 1/2" longer than my stock shock. Guess what? It drops right in with no modifications required what so ever! The bolt holes are the correct size. The clevis width is perfect. And the top eye width is the same as well. I just put it in (that took all of 20 minutes) and took the bike for a spin. Whoo Hoo! The harshness is gone!
The Kawasaki shock is nitrogen charged and is fully rebuildable (unlike the OEM Triumph unit). The spring rate feels fine, with room to adjust preload in either direction.
So...Start Shopping!

Awesome I wonder which other Kwaka shocks are the same, possibly a newer model, then one would be assured of a shocky in better condition. I'm off to the wreckers come monday.

I believe there is no such thing as accidents. When I ride I must leave enough room for others stupid mistakes, added to that is enough room to make my own.

Rear ride height is raised a bit with the stock dog bones. This sharpens up the steering a bit, and may lead to increased nervousness at high speed. Upon taking a longer ride today, it does not seem to be a problem, though.
I live on some pretty rough New England roads and this mod has proven to be excellent, so far. A side benefit seems to be that there is less chain slapping noise (my chain is whipped, and next on the list for attention).

Be aware that in 1994, Kawasaki made both a ZX7 and a ZX7-R. The ZX7-R had a remote reservoir shock that may pose some problems with installation, although I had read here that somebody had installed a Ninja 600 remote reservoir shock by moving the battery and some other components around a bit.
I am sure that there are lots of shocks that can be made to fit with just a liitle bit of work, but the ZX7 shock is a "drop in" solution.

How long was the zx7 shock?

If I measure mine on the center stand I guess it would be fully extended???

I did not measure it when I had it in my hand, but from the e-bay ad it looked like it was around 13 3/4" eye center to eye center. The stock shock was something like 13 1/4".
That 1/2" difference will lift the rear of the bike 1-2" depending on spring preload.
I love the way it makes my bike handle the bumpy twisty back roads of Western Mass.
