Re-jetting with New muffler w/Quiet Core Insert

Recommended Posts

I have a 2004 CRF 250X. I just purchased a FMF Power Core 4 S/A Muffler and put it on my bike. I need to put in a "Quiet Core Insert". I hope this will place it at or under 96 decibels. I need the re-jetting settings for and to see if anyone else has put this muffler on their X and how they like it or not like it. Can anyone help? 😢

Try it stock first, thats what I have learned. Then at least you will know where you stand, if it doesn't have that "lean bog" you know you aren't too lean.
