05 crf250r Valve Lift

Hi guys

I was wondering if anyone could tell me how to check the valve lift duration for the exhaust and inlet valves for a 2005 crf250r? I am trying to find out if it has a stage 1 cam instead of a standard.


AgentSmith is correct.....if its a Hotcams it will have an "HC" somewhere on it and for that machine it will also have two digits on it, most likely on the heel of the cam. If it is their new stage 3 or Gold Series cam it will not be black....instead it will just look like a billet aluminum cam and somewhere on it should be "SF" followed by a series of digits and it should also still have "HC" or "HotCams" somewhere on the cam
