EBS- engine braking system, most of them has the ebs sticker on the clutch cover or on the bike somewhere. by looking it up, it seemd you have it on yours. so the belt shouldnt have alot of play in it. here is the part number for you.
3211069 BELT,DRIVE,ENG.BRK.(5) you may ask a dealer to check that number for an updated one.

 

Mine doesnt have the sticker, but my dads 03 Sportsman 500 HO does. Hate to tear it apart just to see what it looks like..lol.

Anyone have a picture? Or maybe I can take a picture of it this evening and post it up.

Thanks for the help! The number on my belt is 321107.
