My first chore was to pull the upper end and see what I have. Before removing the heads, I figured that it would be easier to take out the inlet nipples first. The first thing that I noticed was that the rear nipple was not installed correctly. It sucked air between the nipple and head, thus removing some threads. It was time to call my old friend Otis to have him weld, machine and rethread the head. He is semi retired from building bikes. Machining what ever you need. Expert welder and one heck of a frame man. 100_0408.jpg100_0407.jpg100_0385.jpg100_0405.jpg100_0406.jpgOther than the nipples, these heads are perfect !!! The threads are all good. No broken fins. Exhaust flanges are perfect. Seats look good.
