Jetting question for 300EX

I just bought a 2002 300EX, I purchased the K&N Power kit for it; I have put the filter and outerwear on it. I will be getting a White Brothers pipe in a few months, will I get any gains if I re-jet it now; or should I just wait until I get the pipe, and just jet it the one time. I was just curious if anyone had added the filter and jets, while still running the stock pipe and noticed any decent gains.

It would be a good idea to re-jet right now for just the filter, then when you get your pipe just take the drain bolt off the bottom of the carb and screw in the larger jet for the pipe. Its Very simple.
