This maybe a dumb question but...can I assume we are talking Keihin jets and NOT dynojets for the main jet considering they are different numbering systems?

No - I am talking about jets. I could care less about who's jets or what numbering system. A specific size hole lets a specific amount of fuel through it regardless of what number is is on it. If the mixture is too rich, you need to decrease the amount of fuel. I always change in steps of two to save time. Perhaps Dynojet has double the size choices than Keihin or Mikuni which means you will have to go down more size numbers till you get to the right mixture. If this were the case, you would get to the right mixture more quickly when using OEM jets versus using Dynojets and typically a single size change is undetectable to a tuner. Go down in two size increments till it runs cleanly then go back up one if you want to.
