Description
The 2-Stroke Speed Carburetor adds a boost of power to nearly all 2-stroke 48cc and 66/80cc motorized bicycle engine kits. With .72mm fuel jets (larger than the stock NT carburetor that comes with most bike engine kits), more fuel and air are able to enter the carburetor, resulting in higher speeds.
This carburetor has air intake & discharge port diameters of 3mm, larger on both sides of the brass slide, giving you much better idle at a lower RPM than other carbs. Installing this on your 2-stroke engine will have you flying down any track with more low-end torque and better fuel economy than other high-performance carburetors. Whether your motorized bike needs a boost of speed or you’re looking for better fuel economy, this Speed Carburetor will give you the performance you’ve been looking for.
