Jetting question

[IrvSLedman]

Hey guys, Im going to be getting a cobra Jet system for my 350x for real cheap soon from a buddy since he knows the pickle Im in, and Im going to need to re jet it, right now as far as i know its got the stock jet in it, and im gonna be hard up for cash doing all this to be ready for Tf so I cant really be playing the guessing game..ya get me? what Jet do you guys suggest?

138 is stock, i would start with a 145 and see what its like my stock bike i just had to jump up the main on it to a 150 and all it has is a pipe. I would start with a 145 but it could be between 142-150

Hard to tell , But i would buy 145 , 148 , 150

Or just buy a jet kit package -
