Frequently Asked Questions

How many main jets are included in the performance jet kit?

Sixteen Keihin-type main jets are included in four sizes: #140, #142, #145 and #148, with four jets of each size.

Are all 16 main jets installed at the same time?

No. A four-carburetor rack uses one matched size across all four carburetors, so four jets are installed and the other three size sets are retained for tuning.

Which carburetors fit this main-jet kit?

It is intended for the 1969-1970 CB750K with Keihin carburetors. Confirm Keihin carburetors and the existing jet style before installation.
