There is no fuel pump to break (or weight the bike down), I could run the carb with a soda bottle if I had to. There are no complex computers to break and brick the bike.
Beyond the reliability, the real value of the carbs is the FEEL. This bike is analog, the rumbling sounds, the brilliant popping and gurgle on deceleration. Its a motorcycle, mechanical gear changes, cable operated throttle, controlled explosions.
We loose something with tft displays, riding modes, non analog throttles, and every granny safety algorithm in between our brains and the rear tire.
