adjuster on the shock is the rebound adjuster

adjuster on the rezzie is compresion adjustment.   only on 87-92 lt250r shocks. 

do what they sound like.  rebound is how fast it rebounds after a hit.  and compresion is how stiff it is on the compresion stroke. 

if the shock has never been serviced, you probably won't feel a differance in the adjustments.  oil breaks down, passages become clogged. 

does your shock have the bottom out bumper on the shaft. if not it needs rebuilt.
one thing to know, you never buy a shock that has one missing, just spend the cash on yours to get rebuilt

the bumper is about 2 in long and made of a rubber.  should be on the shock shaft opposite the shock body. 


i wasn't talking about the shrader valve.  87-90 250 shocks have a round black knob on the rezzie which is for compression adjustments.  if your rezzie is just round without that, you must have a 85-86 shock. 

87-90 shocks have a round black adjuster that slides in and out on the shock oppositte the shock body.  thats for rebound

what year lt250 do you have?
