I have no problems with 03 stock jetting for hardcore Motocross Racing, but MXA and Dirt Rider prefer near the same setting to run in their CR250/03 test bike -
my ask:
Have anyone test their setting?
>>> 400/410 main, 4.25 slide, 38-70 needle/1clip, 35-40 pilot
stock is 430main, 4.0 slide, 38-73 needle/2clip, 30 pilot
What is the different?
And is it realy worth?
Thanks for help!

I NOTICE THAT MXA THEIR RECOMMENDATIONS CHANGE FROM MONTH TO MONTH.

I AM IN THE SAME AREA AS THEY ARE TESTING. PROBABLY HAVE TO FIGURE THE JETTING TO YOUR SITUATION IS DEPNEDED UPON WEATHER AND ELEVATION.

I THINK THESE GUYS USE THESE HOP UP RECEOMMENDATIONS TO SELL BIKES FOR THOSE WHO ARE ALWAYS TRYING TO IMPROVE AND EVERY MONTH SOMETHING IS ADDED OR IMPROVED.

i ride the same tracks as MXA, they said the 01yz250 jetting was spot on, ive had to lean 2 sizes on the pilot and 2 on the main. ive found similar things with pump gas, race gas and also some of my more special blends that one would think would lean out a rich condition.

Magazines are not a good source of jetting or tuning info IMO.

They work pretty well for kindling, though. :flame:

I'm sure its possible that not all the bikes run exactly the same. Some bikes make like it rich others lean. You just have to get to know your bike. I'm sure it doesn't hurt to try their recommendations though.

In some cases, it could.
