Okay since I re-did the shee and got everything cleaned and nice it's time to get this thing running right.

I've read and re-read the jetting faq and this is what the math says I should use as a baseline.

 

No Airbox Lid -> +2 sizes

K&N -> +5 Sizes

Pipes & Silencers -> +8

60-90 degrees weather -> no change

700ish' above sea level -> no change

High Humidity -> +2

 

So just guessing here my baseline should be:

2 + 5 + 8 + 2 = 17 Sizes Larger? She had 200's in there so my baseline is 370? Largest I have is 310's and she still won't rev out at WOT

 

 

I've got to get this thing figured out, silly 400ex is smoking me.

You should've left that out! :rotflmao:

 

Anyways, your mods are very similar to mine, and you elevation and temp are very similar as well. I run 320's with 27.5's. Maybe buy some 300-330's and go from there. I always like to run my stuff a touch rich... so you might be right in the same window as I am.
