James,
If you are out there, I have a couple questions regarding one of your jetting kits and compatibility.

Situation:
I had a 2007 CRF250 with a FMF 4.1 Exhaust and the accompanying megabomb header. I ordered a JD Jetting kit, put the jetting according to kit instructions and all was good.

Settings = taking out the stock 175 jet and replacing it with a 180 jet and using the red colored needle with the clip on the 3rd groove from the bottom

I just recently purchased a 2009 CRF250 and moved over the following...
1) Header and Exhaust system
2) Quickshot
I was going to move the jetting over but the 2009 had a 185 jet in it already so I didn't do any jet mods and just moved the full exhaust system over along with the quickshot.

The bike runs fine but backfires a lot. My questions are...

1) Do I need to jet my 2009 bike any different since moving over that exhaust system
2) Am I okay running that pipe system and quickshot on my 2009?

Any help would be greatly appreciated...Thanks!
