Default Needle Testing

Having read a bluzillion jetting posts I decided to run a test on my bike. Quick and to the point.
2011 ec250
AS2 36mm
6.5 slide
55f
1800? elevation

JD blue #3 38/170 AS 1-1/2
Seemed blubbery down low but torquey definitely rideable, clean throughout WOT. Idle was decent at about 1100rpm

NEDW #3 40/175 AS 1-1/4
Bottom end was rowdy, not overly lean but crisp and definitely not blubbery. Mid to WOT was so rich it seemed to want to drown out the bike. I bumped the pilot up to a 40 since this needle is a few steps leaner than the blue. Saw in some other posts that it might be a good starting point. The 175 might have been overkill but I didn?t have any smaller mains but a 165,168, and 170. They seemed a little lean to begin with.

NEDW #3 40/170 AS 1-1/4
Same bottom, but mid to WOT was still super rich. I was really thinking I would notice some difference but it was minor. So is going to a 168 the next step or moving clip positions? Will moving the clip mess up my awesome bottom end?

Appreciate the help.
