Мотоцикл Урал. #81. Втулки, седла, клапана. Обработка и притирка.

We've replaced the valve guide bushings, and now we need to ensure clearances between the bushing and the valve to prevent the valve from "hanging" open when heated and colliding with the piston. To do this, we'll ream the bushings. To ensure alignment between the new bushings and the valve seat chamfers, we'll countersink the seats at 120, 90, and 60 degree angles. Finally, we need to lap the valves to the seats and check the quality of the lapping. This entire process will ensure reliable and long-lasting operation of the engine's valve train. Enjoy!
