General information about this item

Product info
The new 130 main jet for the accelerator pump (Part No. 1-1135) provides the correct amount of additional fuel in the BMW Isetta carburetor when the throttle is suddenly opened. Especially in restored vehicles, replacing worn or clogged jets often eliminates acceleration hesitations and jerking. It should be installed as part of a complete overhaul of the accelerator pump and carburetor cleaning.
