Due to the popularity of the single carb conversions, the alloy manifolds in this kit are no longer made. We do though believe this may be successfully resolved using our rotatable 45 degree boots where do need someone to confirm. Please call the office 0747712677 to discuss if for what ever reason wanting to fit twin carbs.

The Mikuni VM carb incorporates many upgraded features not found in the stock Amal carburetor with the most notable being a heavy duty hard chrome plated bronze slide for decades of consistent service. All this means going  faster has never been so easy, say goodbye to hard starting, irregular idle, hesitations, flatspots and most of all short carburetor life.  The Dual Mikuni VM34 carburetor is easily fitted to your Norton and the improvement is instant. There are jets provided that must be changed as well as spares for fine tuning the top end at WOT. Climate, altitude and fuel density from different octane fuels all have varying effects on final fine tuning as does cam, exhaust and cylinder head porting etc. In the jet kit is a range of jets for the Mikuni VM34 carburettors to best suit your Norton on Australian fuel but please do contact us if you believe further fine tuning is required and we can guide you through the process. Once tuned a VM Mikuni will not go out of tune for many years.

You will instantly experience better throttle response, improved acceleration, increased horsepower and torque.  In a number of instances Dyno tests have shown improvements of up to and over 25%  when fitted to OEM carburetored engines.


If wishing to modify your existing Norton cables to suit the Mikuni VM 34 or use a different air filter rather than the provided POD Air filter you can purchase the carburetor, tuner jet kit and or what ever other components you want individually by following the directions below.

On the main menu to the left of the page, hover over the carb listing for Mikuni VM Carburetors and then select VM34 from the drop down list. When clicking on any individual size Mikuni carb from the drop down list it will put you into a page showing not only the Mikuni carb itself but also any items relevant to that carb, being Mikuni jets, Mikuni flanges, Mikuni carb tuning kits, Mikuni cables , Mikuni throttles, Mikuni air-cleaners and a range of Mikuni carb to OEM air box adapters etc to also suit. This also makes alternate jet selection easy for you if you have your own spec or wish to purchase extra jets as only the type of  jets that fit that particular carb are shown.
Click on the carb itself if wanting to view the full details and or to make your purchase. Then back arrow back in the carbs main page and go into the tuner kits, which show in the sales drop down list the jetting kits we have for confirmed suitable engines for that particular carb.
