This upgrade will not only improve your bike’s throttle response but also increase its overall performance.  This is a great starting point for reviving older bikes.

WHAT IS A MIKUNI CARBURETOR, AND WHY IS IT SPECIAL?

Mikuni began designing and manufacturing their carburetors in the 70s and they have maintained their reputation as a leader with decades of experience in the carburetor industry.  Mikuni Carburetors have been tried, tested and refined over those decades to provide you with instant throttle response and extra power..
 
What makes these Mikuni Carburetors so special? 
 
Any engine builder will tell you that Power comes from air and oil flow mixed with appropriate fueling. The Mikuni HSR carburetor excels in creating the best airflow possible while having a much more direct fueling system. Mikuni HSR carburetor achieve this by eliminating the throttle-based butterfly valve and airflow-based slide, and replacing it with a throttle-based slide. This leads to a straight line of fire for your fuel needle directly into the intake.
 
The result is a significant gain in top-end power and bottom-end torque, along with increased throttle response, making for a much more enjoyable and responsive riding experience.
