xr650r fcr41 needle

Going to be switching over to a fcr 41 or a tm40/42 soon. I had a tm40 on my last 650r but wanted to try a fcr this round. Does anyone here have a sold needle for the fcr. Perhaps a setup that's been dyno'd?

I had my settings down sold on the tm40 but don't want to spend forever chasing the correct needle on the fcr.
