Honda Spree Carb Kit conversion

The Details ⚙️

Here it is — the ultimate carb upgrade kit for the Honda Spree and 1988–1989 Elite SB50. This setup completely transforms how your engine breathes, delivering significantly improved airflow, throttle response, and overall performance compared to the restrictive OEM setup.

At the center of the kit is the Polini CP 21mm carburetor, paired with a high-flow intake system designed to maximize air and fuel delivery. This is not a mild upgrade — it’s a full step into performance territory and pairs best with other supporting mods like a pipe and proper CVT tuning.

Everything needed to make the conversion is included, from intake components to fuel delivery and throttle control. It’s a complete solution built for riders who want real gains, not just incremental improvements.

Fits Honda Spree and 1988–1989 Honda Elite SB50.
