big bore end cap= rejet?

[big-guy]

I have a 2" end cap (stock arrestor with the guts cut out), stock everything else. Running at sea level basically. Do I need to rejet? And if so, to what?

Id imagine you would, because you are moving more air now

I did that when I first got my bike and I never rejeted it. Just ride it, you'll be able to tell.
