CRF's Only Forums

I just bought a crf 250 r 2006 , I'm doing a rebuild but the head looks great , I want to do a kibblewhite kit , but how do i tell what kind of valves are in it now , if it has the kibble whites or stock , any help is appreciated

I want stainless valves , is there a way to tell what I have in my motor now is what I mean

the oem exhaust valves are a two piece construction. the has a lower grade stainless so a magnet will stick to it. the stock intake valves are titanium so you can weigh them. visually you can tell as well if you know what you are looking for.
