dyno jet convertion data

Post by warby221 »

Found this on another forum when looking for jets kits
As you may know Dyno jet kits come with an assortment of jets that don’t seem to follow any conventional sizing
IE if you have a 190 jet from a Dyno jet kit it’s a different size to say a 190 jet from a standard Honda carb
Basically it’s to stop one person buying the kit and passing on the jet sizes to others
Well here are the equivalents

Ahh!
Excellent find :thumbup:
It also explains why there is such an argument beween the 170 and 190 jet in the Storm :D
