can anyone help?

thanks

Loosen the two large bolts that hold(clamp) the carrier.
Loosen the caliper bracket (clamp) bolt.

Turn the carrier ussing a large pair of channel locks until proper slack is on the chain.

Tighten fasteners.

 

do a look up there are lots of posts about it

 

Yep... Lots of posts. The rear shock needs to be fully compressed (this is the point in which the swing arm is at its longest distance) and then the chain is to have 1/4" "flop" at this point.

 

Negative on the shock compression! During the 98 model year, Polaris changed from non-concentric to concentric drive. If your rear brake is located back on the axle, you have concentric drive (which a 99 Sport is) and you don't compress the shock for adjustment.

 

whats the difference between concentric and not?

 

Other than the brake location. The concentric design keeps the distance from the front sprocket to the rear sprocket equal through all positions of rear suspension travel.

 

Yep, my mistake....keep forgetting about these "newer" things.

Thanks for correcting me Ken.

 

With all the Pred testing going on....seems that's about the only thing I remember about the Sports/Scramblers. [img]i/expressions/face-icon-small-smile.gif[/img]

 

Hey Modquad, did you get that 5" on yet and try it out, or are you still buried in snow?
