No it will not. You probably don't NEED to rejet at all. If the manufacturer suggests it for your bike and pipe combination I would follow their advice. If they do not suggest it I would use a dyno to get the best performance from your new setup. Keep in mine your new exhaust only lowers the back pressure. You haven't changed the intake parameters at all as far as airflow. So any additional air going into the cylinders due to your new exhaust will only be because of the reduced volume in the cylinder while the intake valve is open. This is a rather small amount, so don't get all crazy and jump several jet sizes at once.

First off did you buy it new? Second has it gone through its break in tune up yet?Did you do the re jeting? My guess is it was re jeted wrong & neeeds to be re jeted again or could also need more air(upgraded air kit) or a tfi or power comand fuel mod.My bike also poped untill I did the air & fuel upgrades & them upgrades will also give you a much needed house power needed for this rig.
Bring it to a shop & have it looked at.......
Good luck

You will have to adjust the float pin of tht particular carb and don't remove them off the rack..just pull them out of the engine and work on the one tht needs attention.
Hope this helps!

I would double check compatibility and wiring hook-up of the A/M CDI. See if the previous jets (if undamaged) improve top end. The leaner, the meaner!
