Please select your model from the purchase drop list.

IMPORTANT NOTICE- For applications where replacing  40mm Bing Carbs which have a 52mm outlet spigot diameter at the motor end, we fit a larger 52mm sleeve so as to properly match your OEM rubber boot (if replacing a 40 with this carb the total length will be 5mm shorter requiring a push forward of the air box connector). With all others do confirm on the smaller motors that your carb dimensions match (+ – mm) as per the picture A=44 B=50 and D=110mm, some very early models do differ.

 Going  even faster has never been so easy when stepping up from the stock carb to either a VM mikuni to even better with a TM flatslide, say goodbye to worn old flooding stock carbs, hard starting, irregular idle, hesitations, and flatspots.  The Dual Mikuni TM34 carburetor kit is easily fitted to your BMW R60, R75, R80, R100 and the improvement is instant. This kit includes our silver anodized sleeves fitted to both ends of the Mikuni TM34 to match the original Bing carburetor dimensions. There is also a pair of inner throttle cable wires provided to replace the existing inner cable where you are required to solder the provided nipples to the base of the new wire.

The supplied carb dimensions are 50mm inlet x 110mm front to back length x 44mm outlet.

The most commonly suited jets for Australian fuel and conditions have been fitted 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. 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 plus 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 a different air filter rather than have the sleeve fitted 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 TM Flatslide Carbs (non-pump) and then select TM34 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.

    !977 BMW R/75/7 U.S. model. Stock engine. Improvements are everywhere -vs- the stock Bings. Much smoother idle and warm-up. Low end power is much smoother. Roll-on is smooth and much more responsive than Bings. I was afraid the throttle pull may be a bit much, but it is not an issue. The carbs are a perfect fit with the stock BMW intake components. I am running the carbs as shipped and set-up per my instructions. MikuniOZ has done a great job figuring out a direct swap with no headaches.
    Anyone with a stock or modified BMW, this set-up is definitely a ‘must have’.

    Fast delivery, easy straight forward fit and easy to tune.
    massive improvement in throttle response and idle quality.

    Building custom bikes you want to ensure your machines run in tip top shape. So when it came time to find a proper set of upgraded carbs it was clear who we needed to go with. Tom answered all my questions and even directly called me to keep me updated. Once the carbs came in it was unboxing long lost treasure. They’re beautiful!! I wanted to mount them on a shelf to display but we quickly got them on our custom BMW R65 with the Siebenrock 860cc big bore. A quick setup and custom throttle cables later the bike was idling perfect. The kit comes with everything needed to get them mounted up and a good write up on settings and procedures. Highly highly recommended to get yourself a set of Mikuni carbs from the gang at MikuniOZ. You won’t find better service and craftsmanship.
