Mikuni RS 34mm Carb Kit – Honda SOHC CB500 | Inline 4 | 1971–1973

Unlock significant performance gains with this Mikuni RS34 Carburetor Kit, engineered specifically for the Honda CB500 Four (K models, 1971–1973). Designed to replace aging OEM carbs, this new rack of genuine Mikuni RS-series flatslide carburetors delivers over a 25% increase in power while maintaining smooth throttle response and eliminating flat spots or hesitation.

Kit Includes:

• RS34 Mikuni Carburetors (pre-jetted and ready to install)

• Rubber reducing boots and clamps (adapt 40mm carb spigots to 36mm alloy manifolds)

Optional Add-Ons:

• Throttle and cables (select in the dropdown menu)

• Air filters (sold separately)

Key Features:

• Direct fit for Honda CB500 SOHC (K/F models)

• Not compatible with the OEM airbox

• Improved throttle control and fuel delivery

• Ideal replacement for worn OEM carburetors

• Reduces the risk of rebuild failures from poor-quality aftermarket parts

Important Notes:

• Your original throttle cables will not work with this setup.

• The throttle cable connects on the left side of carb #2 by default, with the option to relocate to the far left-hand side. Please notify us at checkout if you prefer this configuration.

• Verify carb spacing and intake manifold dimensions prior to ordering, especially on bikes with engine swaps or variations between early and late SOHC models. Minor spacing discrepancies (1–2mm) are usually manageable with rubber connectors.

If you're serious about riding and enjoying your CB500, this RS34 kit offers a modern, high-performance solution that far outpaces the cost and risk of rebuilding your old carbs.
