General information about this item
Product info
The size 50 idle jet with part number B7-03-228 for the Zenith KL 10/11 carburetor in the BMW 700 425 engine and in the Kraka determines the fuel supply during idling and transition phases and is therefore crucial for a stable idle speed. As part of a carburetor overhaul, it replaces clogged or worn original jets to restore the original idle behavior and smooth throttle response. Careful, clean installation and the selection of the correct jet size are essential.
