Mikuni VM smoothbore 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.  This kit retains your OEM configuration with custom adapters that are only available at The Power-Barn!   We are the only company delivering true bolt-on carburetor kits for OEM use on the CB450 motorcycles.

This Mikuni VM32 kit is an easy bolt-on replacement solution for all 1968-1974 Honda CB450's, the CL450's, and 1974-1976 CB500T's.  The kit replaces the OEM airbox/filter setup and utilizes the OEM throttle assembly.  The kit is best suited for use with the original OEM configuration of the bike and will retain the original side covers and battery box location.  Modification of the side covers is not required with this kit.  In addition, the right side carburetor comes with a pull style choke to minimize interference with the fuel valve.  Alternatively these carburetors can be configured to accept a 2 into 1 style cable choke that can be mounted on the handlebars, please inquire for details.

Mikuni VM32 and VM34 carburetors are both available, the VM32 will be better suited for low end torque and low RPM operation while the VM34's will flow better at higher RPM's thereby producing more horsepower.  All of the following is included for a simple installation:

This Mikuni VM carburetor kit delivers exceptional throttle response and unmatched power control.  The kit comes pre-jetted for immediate installation and tuning and performance specs have been developed over the years to suit a wide variety of conditions, however 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 additional genuine Mikuni parts and accessories are always available at low prices.  Alternatively these kits can be built to your own jetting specifications. Please ask us how.

Kits come with universal style cables which will require some cutting, crimping, and/or soldering.  Instructions are included to make this as easy as possible.  We can assemble your cable in advance for an additional fee, please inquire.  In addition there is now a custom Motion Pro throttle cable made exclusively for our kits.  These high quality Motion Pro cables are available in either black or grey housings.  You can select your cable option above before adding to your cart.  Replacement cables are also available.

It has come to our attention that some "other" retailers are selling these kits incomplete. They don't include all the necessary items for a successful installation and that forces you to buy more items, possibly at a higher cost. These kits from The Power-Barn are 100% COMPLETE, you will need nothing else for installation.


Please feel free to contact us with any additional questions or requests, we are available by direct line, IM, or email.  We are available for tuning and setup questions as well as continuing product support after the sale.
