Help me please!! How do I tighten the chain on my 97 yamaha warrior??? A detailed answer would be GREATLY appriciated.  

there are two long bolts sticking out on the bottom of the carrier. i belive they are 10mm size bolt. lube them up first then unloosen the nut on the inside then screw in the main bolt. dont do it to much. becuase it will crack your motor. like mine. do the same amount of turns to both sides then tighten the innner screw to lock the bolt
