Stock Pilot Rear Shock by hoser..

Wet Willy gave me a pair of his old Pilot shocks to play with, this one looks like 
it was off one of his jumping machines, notice the bent shaft.

The service manual does not get inside the rear shocks so I decided to open one up
the stock shocks are a well built unit and tuned fairly well for the average rider riding 
on average terrain they could stand better valving for the rider that likes to push his 
Pilot to the limit in the rough stuff, I have found that by simply changing the oil from the
stock 0 weight oil to a 10w oil for riders under 200 lbs or to a 15w oil for riders over 
200 lbs the shock valving is much better for the extreme riding conditions, even with 
the 15w oil I feel the shocks could still stand a little more rebound dampening on 
smaller bumps and whoops.

Pictured below is the complete insides of a rear shock, they come apart pretty easy.

The shaft could probably be straighten and the shock reused but I think I am going to study 
the valve stack and add some more rebound in my spare shocks to see if I can eliminate
some of the pogo stick affect you sometimes get when blasting through the whoops.
The oil that came out of this shock was black and smelled burnt.
