The engine is back in the frame and the pistons and the cylinder of the 78 engine are mounted. Still got some work to do on the cylinder head. I had some trouble with two exhaust valves. I guess they are not straight anymore. Sadly I’m not having the tools to measure that – so it’s just a guess. Anyway, last week a parcel from Germany with many new xs750 Parts arrived. Including two brand new exhaust valves and a complete set of gaskets. I’m quite curious how it will work with the two new valves.
