I know on Buttfungus's website he has the Mukuni VS Dynojet comparison. My question is how does a Keihn jet compare in size. The same as Mukuni?

 

well, you can't really compare them. A Keihin is a different brand of carborator. The Keihin, and Mikuni jets are not interchangeable. Dynojet is a company that makes jets that fit different brands of carbs. I'm pretty sure you can buy a dynojet kit with Mikuni jets, or Keihin jets.

They are two totally different jets for two totally different carbs, and thus you shouldn't need a comparison

 

Actually the reason I ask is I'm trying to jet my girls quad. I have a 150 & a 155 Keihn jet. Her Big Gun suggested a 152. I'm now running a 165 Dynojet. Seems kinda rich, so I'm asking to see if Buttfungus's comparison chart could also apply to a Keihn jet... assuming they are rated like a Mikuni.

 

ohh, ok, well, ask on the Honda or Yamaha forums, I think honda and Yamaha uses Keihin carbs, so you might get a better response.
