im runnin the same pipe but i didnt rejett. i jus put a k&n filter and its runnin great and i could tell a difference when putin the pipe and filter together.

i'm about 100 ft above sea level, my 250 has a T-4 full exhaust, UNI air filter. my e-clip position is #4 (one notch below stock), and my main for the time being is a 102 K&N/Keihin jet.

last time i was home from college and riding it was ~70 degrees. even with the airbox lid on, if you stab the throttle from idle to WOT it dies out. I just ordered 5 new main jets from my parts guy- 108 , 110, 112, 115, 118- to insure that i can get it jetted right, because its a bit lean right now.

these hondas run as lean as possible from the factory, even with a slip-on you'll be doing yourself a disservice by not re-jetting. where do you ride (city, state)? elevation plays a big role in jetting.
