HI everybody can i rejet my bike without touching the airbox (leaving the original lid and snorkel), if yes what would be the jetting specs?

 

i would rejet and just remove the snorkel, thats how im running.What exhaust you running? If stock id start with 125 main, a/f screw 2.5 turns out, stock pilot, N1TC needle second clip position from top.

 

I have a 2 bros. slip-on, the only mod for now but since i'm a novice a I need advice... The next step will be the 13t sprocket (this winter) and then at spring time I should bring it to my dealer for the jetting.

 

Definatley do something with the airbox lid. Either get the kdx snorkle, don't run a snorkle, or don't run a lid. Everybody on herehasthere reasons for what they run. I like the kdx snorkle and it is working well with my set-up. The amount of air the stock snorkle lets in is pathetic!

 

IF you dont rejet definitly leave the airbox alone or you will create more problems than you solve.

That said, rejetting & removing the snorkel &/or lid is definitley the way to go. Your pipe is decoration without doing so, the jetting & opened airbox is what makes the pipe worthwhile in the first place.

Id start with what EMS said for jetting as long as you are not at some freakish elevation. Drill your slide hole too. 7/64" is what I had with the jetting EMS listed, went to #32 with my DJ.
