Might be a shot in the dark but here goes...
 

Ok so I haven't been on in a while, but here goes. This is kind of an off the wall question but I see there are a few 450Rs on here so maybe someone can help me a little. I am going to try and help my buddy with some jetting tomorrow who got a 450R a while back and has been battling it ever since. Turns out its got an 05 Carb, but its a 07 model quad. The 07 carbs are different. He has the 05 dynojet jet kit. From what I have read, Kehin uses a different numbering system than dynojet does, but I found a conversion chart online for that. Can anyone tell me what a good baseline to start would be?

And the quad has a K&N and a dg pipe.
