Project: Q+2     -     Entry

Dec 18, 2021 .6 Stock Valve Lift Category: Engine
I wanted to measure the as-delivered intake valve lift on my Revmaster to get some idea of what cam might be installed in my engine. I installed the rocker arm shaft and set the 0.006" valve lash on the intake valve of cylinder #1 per the Revmaster manual. I used the JBugs mounting trick from yesterday to get the dial indicator set up.

Maximum valve lift measured 0.347 inches at the valve. Adding the 0.006 inch valve lash gives ~0.353 inch total lift. Dividing by the 1:1.1 rocker arm ratio gives ~0.321 lift on the intake lobe of the cam.
