Ok Sorry guys I have been asking alot of questions on this pipe, but I have another question (probably won't be last either). When i jet my Carb, Do i have to adjust anything like my a/f or my needle? Please get back to me as soon as possible.
 
What would i have to move the needle to? Where is the air screw? I know where the a/f screw is but now air screw?

you probalily can leave the needle alone and the airscrew is the little screw beside the gas inlet on the carb. but cant tell if the jetting is off unless you ride it and feel it.
 
Oh, Alright, I have it turned 2 turns right now. Should I keep it like that if I put in bigger jets like 310-320-330?

that jetting seems just a little high but then again the toomey site prolly runs all there machine with the lid off..
usually on the blasters a pipe will make it to were youll have to bump up your main up to 270-300 thats the jetting for just a exhaust...
now the needle jet controls your mid range on your carb the lower the clip the richer it gets stock is in the middle groove you MIGHT end up having to move the needle clip down one slot to get the most out of it..
the pilot jet controls the bottom range of the throttle and if your 2turns out right now you MIGHT wanna turn it out a little more but if you have to turn it out more then 3 full turns then youll need a bigger pilot jet...

the most important thing about jetting a carb is to set one circuit of the carb at a time so if your bike developes a wierd symptom then youll know exactly what caused it..

turning the air screw out will lean the pilot not richen it....
