Z1-R Season 3: Installing Zephyr 400 Carburetors (CVK30) with Stock Airbox.
Choice: For the new season, I chose Keihin CVK30 carburetors originally from a Zephyr 400. Reason: While it may seem small for a 1000cc bike, the 30mm bore is perfect for street riding. It maintains high air velocity at low RPMs, providing excellent torque and throttle response compared to larger racing carbs. Setup: Connected to the stock Z1-R air cleaner box for weather protection and reliability. It’s the ultimate “Grand Touring” setup.
