just a little bit ago I went to ride my 400 and I just put new air scoops, and a new Outwears airbox cover on and I wouldnt think it would need re-jetting but.. I go outside and I start to ride around and once I put around I try doin a wheelie and my back tires just spun and my front didnt even budge to come up, and then I tried to shift through the gears and once I get the throttle about 3/4 the way down in gears it starts to cut out and sounds like a banshee because it pops. Im almost 90% posative it needs to be re-jetted, am i right?

you wouldnt need to with just the air scoops but with that cover you messed with the air flow so you will need to rejet it. You are probibley getting to much fuel.

You mean air and not enough fuel:p

Any performance change(more air intake, more free flowing exhaust, etc) almost always requires some form of rejetting.

Definatly rejet it...running a bike lean is not good at all

i didnt think the cover would need to be re-jetted that kinda blows...

[CannondaleRider]

Yeah, it's do to more air being allowed into the airbox at a given time, when the jetting is setup for the amount of air which was coming in before....thus, to much air=not enough fuel=lean..

Souds like you don't want to screw with it. Try going one or two sizes up on your main and turn your fuel screw out a 1/2 turn. That may not be perfect but is probably good enough.

Personally, I don't like "good-enough" jetting but for plenty of people that's just what the doctor ordered.

Once you have the jets in hand, you can make those changes in 20 minutes. Good luck!

Im kinda like you I want my jetting to be point on if I have to mess with it..
