2007 yz 250 jetting

I just installed a bills mx2 works pipe with a bills mx2 muffler, looking for recommendations for proper jetting with this setup. I already purchased a jd jet kit, just waiting for it to arrive.

Does Bills not provide a chart like FMF and PC?

Nope. Their website doesn't show anything about jetting that I can see I also have to rejet my bike. It's very rich. And have no idea what I should set it to also

Can you not just see what is in there now and lean it up a touch??

Like just about any 250/300

You may have to use a Kawasaki needle holder

Just make sure needle wiggles a bit when in slide
