I know I know, these questions are getting old, but I have never done jetting so I am completely new at this. I have the Yoshimura Full exhaust system, with no other modifications. I plan on leaving the airbox lid on and I won't be able to buy a K&N for awhile. I live in AL so I'm guessing the elevation is below 3000 ft. Are the instructions correct where it says 122.5 main jet? I also want to know what the stock jet is. Please help me as I am in desperate need of assistance.

jetting question

With my yosh system specs say a 150 back in july when installed.
I settled with a 155 & pro design
stock is 130 main & I think 22.5 pilot
I went up one size on pilot
With those settings you should be close though you may want to look for more input on what air mix setting to use.
