I recently purchased a 2001 Sportsman 500 HO and love it. I have noticed a noise only when turning in reverse. Anyone have a similar issue before. All fluids changed and all looks good.

 

Usually wear in cvs will cause clicking noise especially in reverse,normal as machine wears. If starts making noise in forward then time to check for excessive wear (big ball bearings in plunging joints wear wider grooves in channels,cvs on wheel sides wear also) On rare occasions, I have had bad hub bearings,but usually pretty durable.
