Mikuni RIVA Racing Modified Carburetors

RIVA Racing Modified Mikuni Carburetors feature a short press fit air bell that tapers from a massive 70mm to a true 48mm throttle plate. Starting with proven Mikuni Super-BN Carburetors, each one is hand assembled with top shelf components. At the heart of the carburetor is our exclusive "POWER BOMB" fuel atomizer, providing peak performance under all conditions. Hesitation and bogging are eliminated while delivering explosive acceleration and extreme top speed. Kits are pre-jetted for specific applications and include throttle linkage & cable bracket.
