Default 06 250 Jetting Advice

Current setup:
main: 182
Pilot: 43
Neddle: N1EF Clip #2 position
Throttle valve #7

Bike starts easy and idles nicely. This jetting produced minimal spooge and smoke running Motul 710 at 40:1 at 40-60 F, 1500 ft and below. Nice linear power no strong hit. Plug was a nice chocolate brown.

Last ride was up at Elkins still seemed to run pretty well still. Slightly more spooge though. Temps were in the 70s F, 3500-6000 ft. Plug is now pretty oily and black.

Typical riding for the summer and fall will be anywhere from mid 60s in the morning to 80s or 90s and anywhere from 1000ft to 9000ft.

I have the following currently to work with:
Main: 172, 175, 178
Pilot: 40, 48
Needle: DDK

Let me know if you think there are any other jets I should pick up. Bike still currently starts on the choke in the morning and then after its warmed up a single good kick to get it going again.

Also when I bought the bike I checked the see what jets were in the carb it was a real pain to get the carb back on. It was like I didn't have enough room to work with. Anyone have a good procedure to make it easy?
