new slip-on exhaust....do i need to re-jet???

6 posts in this topic

I want to upgrade my Older style FMF exhaust with one of the White Bros E2 slip-on exhaust and I was wondering if I need to re-jet the bike.

A couple of my friends said that since I was just replacing my muffler that I did not need to re-jet.

I have not purchased the new exhaust yet but i want to make sure I have everything i need before I start to mess with my bike...

Thanks for your input!!!

You shouldn't need to rejet, at the most you may need to slightly adjust your air/fuel screw.

I installed the white bro. E2 on my '06 YZ 450F a couple of months ago and have not had to touch the jetting or the fuel mixture screw. Runs great!
