Hello everyone I got a fcr carb for my 05 it came off a 04 crf450r and I'm getting ready to get around to putting it on and I wanna know a base starting point for jetting for it. Here's my little upgrades Full Dasa exhaust, Dasa intake, and open airbox my elevation is about 2000'. So if anyone could give me a general starting point that would be awesome. I will probably have more questions along the way but we will cross that bridge when we get that far haha. Anyways thanks for reading and hope for some help!!

Ok so I'm finally getting around to messing with it and i got the jets out and the main is 165, pilot is 42, and then there's a super small jet and the number is 72 but I'm not sure what that jet does or what it is called.
