Jetting comparison between brands of jet kits.

Recommended Posts

I am a bit confused. I was chatting with a tech support fellow at dynojet yesterday trying to determine what kit was in the bike i bought. it did turn out to be a dynojet kit, but then we got to talking about jetting. He mentioned that dynojet Main Jet numbers (i.e. 160 ect) do not correlate to yamaha or jdjetting numbers. so a 160 DJ is not the same fuel flow as a 160 JD........ so now i'm really friggin confused as to if i'm rich or lean in comparison to the rest of you with 290 kits in our yz250f's. anyone got any insite here?

You can really only compare DynoJet (or repackaged DJ) kits with each other as well as use thier jets to move an increment. James Dean uses Kehien or Mikuni jets, same as oem, partially for this reason. I think DynoJet use thier own jets to 'lock you in'.

I'll never buy a DynoJet kit, this being one of the reasons.
