Thanks a lot shinyribs.
BTW what kind of gauges are you going to use ?
About JBWeld, I was thinking we could go a different route.
What about grinding off the tach drive off of the the camshaft holder ?
That would leave the camshaft holder alone, w / o the tach drive, only then welding a piece of metal cut to size over valve cover would end all leak, seals and related concerns.
Or else the tach drive devoid of internals (tach canle gear) could work as a temp gauge sender location. That temp gauge would measure cylinder head temperature.
Since our bikes are air cooled, this gauge would help monitor engine specially in hot summer days. Racing and dune VW vehicles monitor cyl head temp like this.
