The TM40-6 comes with a cable choke whilst also in the kit is included the optional knob choke assembly. 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. For Honda XR600 and 650 owners wanting even more performance, check out our TM42 Kit. To clarify some commonly asked questions about this carb in regard to a comparison with the 42mm. The Mikuni TM42-6 HSR flows 17CFM more than our TM40-6 and incorporates many upgraded features such as a roller-bearing slide. This does result in more power and also better fuel economy.In the late 80s Mikuni American released the HS40 (TM40-6) as an amazing new carburetor for the Harley Davidson market, literally knocking all its competitors out of the park. We were at the San Jose Custom Chrome Show when it was released and become part of that buzz as Australian Mikuni distributor. This slide type fuel metering device basically made the competitors butterfly type carbs seem like lawn sprinklers. With the huge increase in Harley Davidson sales this became a very lucrative market.
Recognizing the potential of this market and being aware of the efforts of competitors to try and grab back their share of it made Mikuni realize the necessity of replacing the 40 with a carburetor to be the be all and end all of all carburettors. The target was to deliver unrivaled peak performance combined with smoother throttle operation and lighter throttle pull by replacing the metal on metal slide action with a slide running on roller bearings.
Also, a larger fuel bowl capacity was provided but most of all, superior venturi design and fuel atomization resulting in more precise mixture ratios to not only increased horsepower and torque but also to enable the fitment of a larger carb to smaller capacity engines without losing valuable bottom end power, where in fact instead gaining more. In 1994 the HSR42 was born and just like you will if you fit one to your bike, all we could say was WOW.Instant throttle response delivering 25% more horsepower and torque over the stock CV carb before even putting on a real high flow air-cleaner. Unfortunately, the TM42 only had limited sales in the Japanese single market due to it only appealing to the custom fitter as there had never been a cable set or air-box adapter available off the shelf. With the slowing of the Harley market due to fuel injection on new bikes, here in Australia, Mikunioz realized the opportunity to offer Mikunis best Carburetor to the big Jap single market and in late 2015 we released a range of ready to roar direct fit up kits with correct jetting and a few trick mods to make them work better than anything before on big Jap Thumpers. The fuel consumption is way less but when comparing with the TM40 or stock carbs, it all depends on how having a lot more power and torque effects your riding habits. If you can manage to back off and just have your bike perform at its present level youll be surprised by the fuel economy, but of course when the same amount of throttle twist becomes front wheel lifting, breaking traction action, well its hard to not want to go and play. If you have more horses in the paddock and you want them all to perform, you have to feed them more hay! You will enjoy both these new Mikuni carbs whether it be the TM40 or 42 but if the 42 do be sure to hold on extra tight on your first test ride as she may try to spit you off if you nail it too hard.
