Panhead rocker cover hole repair

Pretty common for guys to drill out the cover holes to 1/4" or heli coil the cover mount holes. Who ever did this one got a little carried away and drilled clear into the intake port. I threaded some aluminum 3/8" round stock, drilled and treaded the head. I welded it up at the top and die grinded the stub inside the port. Pretty easy fix and probably can be done with out the welding.


  1. looks like shit! jk in person looks like perfection!

  2. Great repair! Looks good! Mr. Mike is the Mad Scientist of motorcylotomy!
