Every time I admire Ritmo's works when I see Nakajima's blog..
This R100RS has been full restored step by step to fit owner's usage.
Carburetor were replaced.
Stock carburetor is vacuum carburetor so we feel mild power of engine.
When you use airhead at circuit,they replaced with sliding carburetor like FCR carburetor.
You will be surprised with its quick response than stock carburetor.
Quick means sensitive to throttle work. That is good to circuit use.
But normal long touring,I do not recommend such sensitive FCR carburetor.
Meanwhile, I like this grey color,which looks like US force jet planes.
What color does this come from? from Vintage BMW?
