If your camshaft has been reground you need to carefully check that the followers are staying in contact with the base circle, two things can happen. If you have not shortened the follower guides the tappet lock nut will prevent the follower remaining in contact with the base circle. And/or, it the cam has been reground with a narrow wheel the follower foot might be too wide and riding on the shoulder formed when reground rather than the base circle.
