Also, keep in mind, these motor are not quiet ever. No matter what you do you will have valve noise, chain noise, and I swear i can ALWAYS hear the bottom ends on em. Best way to tell if your chain is needs replaced, take off 4 bolts holdin vc, look down front where chain is, if a guide is missing, replace. If chain is loose, replace, If you can see tensioner spring sitting next to cam gear ( yes Ive done what that was like that) then replace.
