MOST IMPORTANT for a rv engine: check if the VALVE is still ok, as good as it was in the factory or if u renew it. 0,05mm it has to be, otherwise the VALVE cant work 100%, which makes a si carb pretty tricky to set = BLOWBACK
checking the RV of a 72.000km Rally 200 built in 1975. ist the very first opening of the engine!!! kindof excited :D runs still okish, gears are jumping since many years, so ist time now to make the engine new :) ist since 1993 in the same hands
