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.
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.
Actual jet sizes are highlighted with a gray background.
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.

For some reason the Dynojets go on the wrong side. The first dynojet is 150 and it goes up from there.
The Dynojets go up in increments of five, they are the jets sell.(ie 150, 155,etc.)
All Mikuni are the jets they sell.

Can anyone verify or deny this stuf?
I've searched and cant find anything on it.

But if this is true, then the "Stage one DynoJet kit" that i got, which is for a warrior, has a 150 as its biggest jet.
If this is all true, then the largest jet in the kit, is actually smaller than then the original jet. Somehow this just doesnt make sense to me... lol

Anyways, if anyone has any other info on this, please enlighten me.

Thanks ya'll!

YA i wanna know to so.....someone figure it out lol
