OK, this is the last time I will ask about jetting, (yah right). I have read here many times that when upgrading to hi flow air cleaner and pipes, the secret formula is a 45/46 slow jet and 190 main jet. My "stock" carb has 45 slow jet and 190 main jet. Is this good enough for the pipe and air cleaner mods???

 

That should do it, if you have any popping back at low speeds, up the 45 to a 46, I would also shim up the main jet NEEDLE with 2 -#4 washers to raise it up so you get on the needle a bit sooner, makes a noticable improvement in performance, there's a post for this in the DIY forums
