My raptor makes a engine noise by the valves and I was wondering if anyone knows how to adjust them or if the engine needs fixing. It started little by little and now its making a loud noise. It stills runs but im afraid its going to brake. And yes its got oil in it I changed it twice after it began to make noise. Please help!!!

 

check the raptortranny.com website and look under guides. there is one for a valve adjustment.
