Take your current KMC chain off now (Their is a removable link youll see it on the left side of the chain youll be able to figure out how to remove it) Then count how many links their are go down to your local Dirtbike shop. And get an RK or D.I.D chain and it will say on the box how many links the chain is then put new chain on probs have to cut it down then bobs your uncle one more piece of bling to add to your mods list
