The 86 200x's are equipped with a 1-2-3-4 dampening setup.... on the bottom of the shock is a little dial.... 1 is soft, 4 is stiff... respectively so....
try it... :-)
tires and pressure also have alot to do with suspension...
Front fork pressure is another big hitter...
And all of them are effected by YOUR weight...
I'm 135 and my 86 200x suspension hardly moves during small bumps.. but big whoops and bumps, it works well...
i also rebuilt the fronts and did a little adjusting with fluid... the front end rides so well now...
