Honda CB 350, 400, 450, 500 Mikuni VM32 Carb Complete Conversion Kit

(1 customer review)

$799.00 AUD

SKU: N/A Category:


This kit includes carb mounting flanges to suit the VM 32 which have a 40mm OD on the outlet spigots. The throttle cable kit measures 850mm end elbow to elbow and has a 10mm thread for connection to the OEM CB throttle housing. You  have the option of the larger 100mm long red POD filters in place of the black 70mm long PODS in the main picture. Please advise us of your preference when ordering if wanting to make either of these changes.

Going  faster has never been so easy, say goodbye to hard starting, irregular idle, hesitations, and flatspots.  The Dual Mikuni VM32 carburetor is easily fitted to your Honda CB 350, 400 or 450 twin 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 VM32 carburetors to best suit your Honda CB 350, 400 or 450 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.

At Mikunioz, for the last 30 years, we have been constantly checking and where necessary upgrading our jetting specs as fuel quality changes. Regular fuel in the USA is 85 octane or 91 in their premium brands which have numerous additives and blends added (basically smells and drys like wood varnish) which results in a totally different jetting spec and product performance. This carb as supplied from the factory will never work on this bike and requires a total re-jet as supplied loose with your carbs or done here before shipping.

You will instantly experience better throttle response, improved acceleration, increased horsepower and torque.


If wishing to modify your existing Honda CB cables to suit the Mikuni VM 32 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 VM32 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. Again thoroughly read the tuner kit description.
If you’re comfortable with making a purchase of the carb, tuner kit any or other associated components, order it on line or otherwise please call us to further discuss your needs on 0747712677.

    Bought this carb kit to get shipped all the way to sunny Scotland ???????????????????????????? as my CB450 K7 always ran like a pig ! The service could not have been better but to top it all it was a simple bolt on hook the throttle cable up and hey presto! Fired right up !! Idle was good straight off , WOW it’s never done that before! Some minor adjustments on the mixture and couldn’t wait to try it out.
    What can I say apart from its a totally different bike , pulling like a good one throughout the Rev range , I could not be happier !
    Had a celebratory beer that night and thought about the recommendations Tom had given and decided to change main jets to see if there could be some more improvement (but have to be honest , if that’s as good as it got I wouldn’t complain) went next jet up that was supplied with the kit and yeah I got even better . I’m super stoked about deciding to purchase this amazing carb kit from Mikuni oz ! Getting this shipped half way round the world to the U.K. even after import tax I saved about £200 as opposed to buying this kit here in the U.K. but better than that is the many years of knowledge Tom is all to willing to hand out to make your bike run the best it can run .
    I’m still messing around with needle heights happily trying to eek out a little bit more from this old bike but as I said earlier , if this is as good as it gets I’m a happy customer .
    Thanks to Tom and all his team at Mikuni oz , cannot recommend them enough!!
