97 scrambler chain and sprockets

[97polaris500]

ive got a 97 scrambler 500 with a low range trans swaped in and 28" mudzillas all around!being that the front tires are sapose to be 1 inch short then the rear having the same size tires is going to bind up my drive line and it has i blow my stock trans so i swaped that out and i went out this weekend everything was fine until the end of the day and i was going through a mud pit and my chain pop off. long story short i got it back to the house and i noticed that my rear sprocket is rear wore and my chain was really loose once i put it back on and my front is worn and missing some teeth! so i figure its time to change my sprocket i know in the 95 sportsman 400 4x4 had the same size tires stock and back then were setup just like my scrambler so im going to swap the sportsmans sprockets onto my scrambler!
now my question is has anyone ever done a sprocket swap for the same size tires?
and what involved in changing the chains and sprockets?
