Needle Shim Kit

Needle Shim Kit

Ref: 220725

Our Price:


Allows precision midrange tuning of the Mikuni round slide carburetor.
A standard Mikuni round slide jet needle has five adjustable e-clip positions that move in increments of .042 at a time (some needles have only one position). This large adjustment can take you from too rich to too lean (or visa versa). This shim kit allows you to adjust your needle .020 or .040 at a time with shims under the e-clip. Kit consists of (4) .020 shims (use 2 for .040).
