Mikuni VM carburetors are the most popular high performance round slide carburetors in the world.  Mikuni's VM series is the proven standard in single cylinder, ATV, motocross, and vintage motorcycles.  The VM series provides a wide range of bore sizes to better match particular engine flow characteristics along with a large selection of tuning components and accessories for tuning to a wide variety of conditions.

Mikuni TM carburetors are the original flat slide carburetor.  The flat slide carburetors offer significant performance improvements over the older style round slide (VM series) carburetors.  This is because the airflow in a flat slide carburetor is smoother and the velocity is higher due to the flat slide and jet block designs.  Higher air velocities create a stronger vacuum signal at the needle jet (emulsion tube) causing more efficient atomization of the fuel droplets.  This creates a remarkable increase in throttle response and power delivery. 

These Mikuni VM or TM carburetor kits are easy bolt on horsepower for the 1977-Earlier Norton 750/850 Commando's. ALL of the following is included for a simple bolt on installation:

• Dual Mikuni pre-jetted VM32, VM34, TM32, or TM34 carburetors
• Rubber flanges
• Manifolds
• Phenolic manifold spacers for heat insulation
• K&N pod style air filters (optional only)
• Throttle cable (dual kits require some soldering of the cable)
  
• Spare jets
• Mikuni tuning manual
• Extra horsepower is always included!

There are VM/TM32 kits for stock to mild and VM/TM34 kits for mild to modified.  Please indicate your year and preference when ordering, or contact us for assistance.

These kits are suited for stock to highly modified motors and will come pre-jetted for immediate installation. Some fine tuning may be required to attain the desired combination of performance, fuel mileage, and drivability. Extra main jets are included for fine tuning and genuine Mikuni parts and accessories are always available at low prices. Air filter options include K&N pod style air filters.  Please Note: Pod filters are a tight fit.  Pancake style filters do NOT fit these setups.  If filters are needed they must be added separately as an option above, make your selection now.  Kits can also be built to order with your own jetting specifications.

WARNING: This carburetor kit will seriously wake up your machine!

Do you want even more throttle response?  Then upgrade your Norton Kits with the Mikuni TM flat-slide carburetors.  The Mikuni TM flat-slide carburetors deliver even more enhanced throttle response and power through their free flowing flat-slide design.  Air flows faster and smoother through the TM series due to the flat-slide design and the jet blocks which help create a smooth bore effect.  The higher velocity means stronger vacuum at the needle jet providing precise metering and better atomization.  Select the upgrade option now before adding to your cart.
