recommended jetting to start with

[blkstangman88]

alright, im getting my exhaust done tomarrow and i got my carb today. all thats left is my oil lines and chains.

I got a deal on a 06 crf450r carb. i realize its a bit big for my 430x build but itll do for now. its a fcr 40mm i believe. what would a good starting point for jets be? if i remeber right it has a 45pilot and a 165main stock. how about the a/f screw.

set it to the factory specs and go from there would be my bet. I think the screw is 2.5 turns out or maybe 2 3/4. Im sure it will start then see how it runs. Then check the plug and adjust from there.
