what did u set valve height too ? something isnt set right or you wouldnt be having these problems recheck it again, did you take the heads off the bike for this install or do it with heads still in bike ? almost seems like the cams are in the wrong spot.... but they have a cut out in them and i didnt think it was possible for them to go back in the wrong spot cuz the cam sprocket can only go on one way, is it possible you put the rear cam sprocket on the front head and the front cam sprocket on the rear head when reinstalling?.... you installing these on an 800 or 1000? gen 1 or 2 ?
