Upgrade your aircooled engine with this twin Weber 34 ICT carburettor kit, designed to deliver improved performance, smoother throttle response and increased efficiency without sacrificing fuel economy. Perfect for 1300cc–1600cc twin port Type 1 engines, this kit is one of the most popular upgrades for both road use and mild performance builds.
Unlike a single carburettor setup, twin carbs allow each cylinder bank to receive a more direct and balanced air/fuel mixture. This improves combustion efficiency, resulting in better acceleration, smoother running and increased power across the rev range. The Weber 34 ICT carburettors are known for their reliability, simplicity and excellent drivability, making them ideal for everyday use.
This kit is supplied with a CB Performance cross bar linkage upgrade, offering superior strength, smoother operation and more accurate synchronisation compared to standard linkage systems. The original EMPI linkage is also included but is not required for installation.
Kit Features:
• Twin Weber 34 ICT Carburettors
• CB Performance Cross Bar Linkage (upgrade)
• Aluminium Alloy Hex Bar with Steel Ball Ends
• Sealed Aircraft Heim Rod Ends
• High Flow Aluminium Intake Manifolds
• Heavy Duty Steel Linkage Mounts
• Gauze High Flow Air Cleaner Assemblies
• Coil Relocation Bracket
• Brass Fuel Tee & Fuel Lines
Factory Jetting (Pre-Installed):
• 1.75 Needle and Seat
• 130 Main Jet
• 52 Idle Jet
• F7 Emulsion Tubes
These carburettors are pre-jetted for standard 1300cc–1600cc engines. For engines over 1641cc, re-jetting—particularly the main jets—will be required to achieve correct fueling.
For best results, twin carb setups should always be properly balanced and ideally tuned on a rolling road to ensure optimal performance, drivability and engine longevity.
Important Notes:
• Will NOT fit 1200cc engines
• Heat riser ports must be blanked off (block-off plates required)
• Suitable fuel pressure regulation may be required depending on setup
