Head job! Not electrical shocks and lobotomizing
The bike!
Brushed the combustion chambers, in-out ports with metal brush and electric Screwdriver. Lapped/grinded the seats with 2 old valves with ok angles (inlet + outlet), carborundum coarse and fine.
Electric Screwdriver held the valve from other side helped a lot. Alternated the directions until the seats looked OK (1.5-2mm wide grinded stripe).
Tomorrow:
.... time for lapping all valves individually without cheating with machine. 4 new CycleX outlet valves and final adjustment of the OK 34mm inlets.
Then assembly the head with valves and springs waiting for final engine assembly.
(when my final parcel from CMSnl arrive with the last o-rings for oilpump and internal oil lines)I hope I can strip the frame clean too. I'll take it to professionals that will sand blast it and paint with 2-comp primer, then 2-comp black. When the guys are back from vacation...
The bikes frame will return to black from red since over 28 years. I hope I can change my avatar this autumn with my old bike in new and better shape.
