Description

A Mikuni TM42-6 HSR flows 17CFM more than the TM40-6 and incorporates many upgraded features such as a roller-bearing slide. All this means going even faster has never been so easy, say goodbye to hard starting, hesitations and flat spots. 

These Mikuni carburetors are correctly sized and easily fitted to your Suzuki DR650 stock air box when using the silver anodized air-box adapter. This adapter is fitted prior to delivery when purchasing complete kits. For this Mikuni carburetor to operate correctly the motorcycles air box must be opened up to allow more air flow in.

*Using a hole saw, a 45mm diameter hole will be a sufficient starting point where alternating between WOT runs with and without the filter access door removed will confirm if you have removed enough material.

*The kit also comes with throttle cables and a 1/4 turn quick action throttle. The carb comes fully re-jetted for your application with spare main jets for fine tuning. 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. Though the TM42-6 will accept OEM choke cables, you have the option to select the kit with or without an additional knob choke assembly.

**Pre 1996 models: Due to starter motor/drain bung clearance issues on these earlier model- two 7mm thick manifold mounting flange spacers are needed to push the carb back. This then requires the shortening of the air-box boot to compensate. SKU: 6478 

You will instantly experience way better throttle response, improved smooth acceleration, increased horsepower and torque.  Plus the bonus of better fuel economy. Dyno tests show improvements of up to and over 25% when fitted to OEM carburetored engines. Be sure to hold on tight on your first test ride as she may try to spit you off if you nail it to hard.
