General information about this item
Product info
The new 125 main jet with part number 1-1131 determines the fuel quantity in the carburetor of the BMW Isetta engine during driving under load and in the higher RPM range. During an engine or carburetor restoration, a worn or clogged main jet should always be replaced to restore the air-fuel mixture, power, and engine temperature to their intended ranges. This reliably restores the Isetta’s original driving and acceleration characteristics.
