Flow rates based on size markings of Mikuni and DynoJet jets are not comparable ..

As a guide .. the chart to the left indicates equivalent sizes based on the diameter

of hole in the jet.

Mikuni jets are chamfered on the inside opening at the threaded end and

Dynojets have a machined flat surface. Keep this in mind when using this chart.

These physical differences will never allow an exact comparison.

*Actual jet sizes for ording


This chart is intended to be used as a tool to assist you in making a more

accurate decision when selecting a jet size range or comparing tuning data

where an opposing brand is being used.


DynoJet jets are marked according to the diameter of the hole in the

jet .. ie: DJ150 = 1.5mm and DJ175 = 1.75mm.

This is not true for Mikuni or most other OEM equivalent jets. This size

Mikuni jet, (N102.221 Super BN), is marked according to its' flow rate,

ie: 150 = a rating of 150 cc of fuel per minute.
