We jetted my 06 YZFs on the dyno and came up with the folllwing for the 450F as the best jetting setup:
160 Main
48 Pilot
Fuel Screw - 1.75 turns out
NCYR Needle on the 2nd position
the NCYR needle is a different needle than the stock one.

Where did you have that done I have a YZ 250 two stroke with a new Pipe and Porting. Would love to get it jetted properly.
