We installed the top cover onto the front of the engine and removed the small Allen plug. We placed a dial indicator onto the end of the cam and checked for thrust. Ideally, we'd want to see something between 0.006 and 0.010 inch, but our initial check of the cam revealed we had no cam thrust whatsoever. Using the plastic cam button, we could clearance until we reached our ideal thrust measurement. We trimmed enough to gain 0.008-inch thrust. From there we proceeded to degree the cam straight up.
