What began as a 'tune up and flip' estate sale purchase of a 1976 BMW R90 got way over the top for my buddy and R65 forum member Mike
Bengt Phorqs Crenshaw.
Long story with several twists so here's the condensed
Cliff Notes version:
Cylinders, pistons and heads shipped off to Ted Porter's Beemer Shop. Ted says the jugs are worn beyond economical repair. The heads are re-buildable candidates but one has a serious valve seat issue. Executive decision made to upgrade with a Siebenrock 1000cc kit with the Nikasil bores, new pistons, rings, etc. and mount the rebuilt heads.
Six-seven weeks pass...
With the hint of Shiner and barbecued ribs, I'm invited south into the DFW MetroMess and spend a morning with Crunch getting the top end installed. I play the role of flight instructor to the fledgling. The Siebenrock bits are jewel-like works of art. The kit includes all gaskets, o-rings and... those bloody, round wire Jesus Clips. Ack!
By now I've discovered I've been Tom Sawyer'd and there ain't no Shiner and there ain't no ribs. In retaliation, I have Mike fit all the parts that have even the slightest chance of requiring a blood sacrifice, including those bleeding circlips, while I drink his coffee. Remember, there ain't no Shiner. Ain't no ribs, either.
Oak's Top End manual, Mr. Clymer's and a call to Ted Porter confirmed our concerns. The PO had mounted the rocker arm blocks upside down and back-ass backwards. All good now.
Today, Bengt Mike sent me a video of the initial start up. Sweet BMW music with the valve lash set just slightly loose for the virgin crank. Mike is excited and has offered to buy me a barbecue lunch this coming mid-week.

Lining up the conrod and piston wrist pin. Intense expression.

Jesus Clip combat. We have a winner!
