has anyone installed one of these? i just installed one for a friend and i am having a little noise from the valve lash. just wondering if this was normal or not. i callled hotcams and have not gotten a reply yet. i set them on .006 intake and .009 exhaust. i broke in the cam for 30 minutes last night on a good trail ride at midnight, boy the neibhors loved me i bet i am going to recheck the cam timing and the valve lash again today. if you have any sugestions or coments let me know.
