Ok, I bought a banshee and it needed some work so I took it apart, rebuilt the carbs and lost a jetting needle. So, I have to get new ones. I have the needles that came with the rebuild kit but I am not sure if I can use them? My bike mas fmf pipes, and headers, vforce reeds and open airbox. The thing that I cant figure out from reading the other posts on jetting is 1) Do I need a particular type of jetting needle for my upgrades and location or is it just the setting of the stock needle that I am using? What should I do? What do I need to buy? Other than tons of other upgrades. i mean for my jetting application.
