jet before or after new pipe

[Dapper]

I'm sure this has been ask 100 times before but, I don't remember if I ever saw the answer.
If I plan on getting a new pipe for my KDX220 should I wait to rejet or do it now? I love this bike and I don't want to screw anything up. It does load up a bit but I'm not fouling any plugs.
Discuss. :moon:

Stock-run a 42 pilot and 148 main
modified, see C. Dave's Just KDX. Jet before and after, yes, it makes a big difference, and at $4.00 a pop, it's not that big of a deal :)

Dapper... I just posted a similar question under the heading "New Pipe/Help. You may want to read some of the responses I received. My last input into the thread also lists what I am now running on my 220. I highly recommend the Gnarly Torque, it will really wake your bike up!
