The 15/15mm carburetor from Bing is visually identical to the original 12/12mm Bing carburetor but offers better filling of the cylinder and improved internal cooling. This significantly contributes to the engine's lifespan. Additionally, the power delivery is much fuller, and even at high RPMs, the mixture does not lean out as much.
The original air filter can still be used, but the system harmonizes even better with the power filter.

WARNING: This carburetor is available with both 4mm and 3.5mm Bing jets. If you order jets, we will include the corresponding jet type.
