Took the bike out today, clear & dry with temps in the high 30's F. I definitely like the N3RF needles better than the NBZY's.
The more I think this through, I'm becoming convinced that the 48 pilots are good, however in order to get the most out of them the butterflys need slightly larger air bleed holes. At least that's my theory. If I'm right, that will take care of the very light throttle low-RPM slightly rich situation.
I'm in no hurry to do that mod, & might wait for warmer weather. As a general rule, with all other things equal carbed bikes tend to run relatively leaner in cold weather, & sub-40 degree F temps qualifies as cold from my perspective.
Perhaps I'll wait til early spring to drill the throttle plates. We'll see. Gotta do this conservatively or risk ruining the throttle plates.
This carb tuning is a risky business, I tell ya.
