hi i have a fmf megamax 2 pipe and i was wondering if i will have to rejet after taking out the quiet core insert,

i will still be running the same number of disks as when i had the quiet core in,


thanks in advance

 

someone please tell me if i need to rejet or is it fine

 

Any answer you get will be purely a guess.Only your own engine can tell you what it needs by way of a test ride & plug read. Only then will you really know.Having said that, let me be the first one to guess! My guess is you'll need to fatten up the main jet if It isn't already running lean with the pipe. Pulling the insert is simply going to increase the air flow. "How much",you say, just go back to the beginning of this reply/
