One Less '83 Vision Rear Shock

Well, quite a while ago, I bought a 1983 Rear Shock for the Vision from eBay. I was planning to eventually upgrade my 1982 Rear Shock to the '83 Shock. Today would have been that day, however...

After several months, I finally pulled the shock out from it's hiding spot under the work bench. Yes, it was indeed a rear shock from a 1983 Yamaha Vision. This is the shock that every Vision owner claims a a great improvement over the rear shock from the previous year. Both rebound and damping adjustments. Outstanding! Before I get started, let me check where the adjustments are on the newer shock.

Gee, it appears that the damping adjustment control has a bit of rust on the threading. I sprayed some "PB Blaster" on the threading and gave it some whacks with a hammer to send some vibration through the control. I still couldn't get it to budge. Spayed it with more "PB Blaster", put the shock in the vise and still couldn't get it to move with a pair of Vise Grips. More "PB Blaster" let it sit for a while, more vibration and repeat. Still Nothing.

I then put a flat head screwdriver against one of the teeth in the control knob with a couple of quick whacks. Still nothing. I was then starting to think that I was glad I didn't install the shock and then try and change the settings. Two more good whacks with the hammer and screwdriver and the damping control knob split in half. One less usable 1983 Yamaha Vision Rear Shock in existence.

Chris, No matter what setting the damping is at, the shock is still better than the 82.
