ok so i have this 03 raptor that i bought tore down to the piston and i put it back together.
it runs great but had this tick in the top end so i went through it .
new wrist pin , new rings , polished bore , cleaned head , lapped valves ,new valve seals, new timing chain and tensioner , new gaskets , new exaust gaskets .
it has WAY more power now ( still not enough , Build over the winter maybe ) but it still had the same tick that is worse with higher rpms. its in the very top end.
i guess im wondering what it could be so i know what to check next. im really only down to weak valve springs , bad valves or bad cam at this point that i can think of.
