Is a 155 dynojet the same as a 155 kahin(sp) jet?

i am not sure but they should be the same. 155 is a size and the companys are diffrent. that is a good question. i would think but i am not sure.

NO they are not the same. Dynojet uses their own special sizeing system. I believe the fuel metering hole in Dynojet jets has a taper (they claim an improved venturi affect or something) so it's hard to dirrectly compare.

Check out zeppelin's third post in his jetting "How-to": http://www.exriders.com/vbb/showthread.php?s=&threadid=221872

The accuracy of the chart is unknown but Dynojet brand jets are NOT the same as other Kiehin style jets (factory Kiehin, RD Precision, etc.).

Are FMF jet kits the same sizing as Dynojet.

I believe the FMF kits are just re-badged Dynojet kits. I'm about 95% on that.
