Did you do a plug chop at WOT before reading the plugs? That's the only way to accurately assess the main jets.

Unless other issues, seems like Mains jet is still too lean....

i havent run it right up to WOT and checked, but i did run it at highway speed for a few miles, bout 70-75mph, and then took the reading from that, its definantly running off the mains at that speed, ive been told that the pilot jets in the carbs on my bike do little more than idle.

my mains should be okay, i might give each of the adjusting screws one half turn to be safe. i cant see it being too ornery, since its been running fine with just main jets up for a while, and not much adjustment is needed, if any at all, since im riding it in the blistering cold the last few weeks i figure thats gonna have the most to do with why my mixture is lean, so a slight adjustment to the mid and lower range, and i figure shes golden. i love how easy these carbs are to deal with.

anyways, so i gave my pilot jet needle screws one half turn in, and actually managed to get out on a warm-ish day, 15-18*c here this afternoon, and went for a nice hard burn down the highway, to reveal a nice, rich, caramel brown plug in each cylinder. so im happy. dont have to screw with the needles, thank god. synced her up, shes ready to groove. i reckon my assumption was right all along, it was the cold leaning her out on me, and when the average temps slide up to the mid 20's i can probably jet down to a 120 main again.
thanks for all the help and info guys, shes good for the season now, hopefully for good, at least as far as carbs are concerned.

Its not running off the mains until you open the throttle beyond 2/3. The speed your travelling at has nothing to do with it. The rpm also has very little to do with it.
The fuel circuit/jet that is used is dependent on the throttle input.
You wont know if you have a correct main jet without doing a WOT plug chop.
Get the bike into top gear really early, then crack it FULL. When you get to just over half of max rpm, KILL SWITCH the engine while still holding the throttle open.
Pull clutch in quickly at same time, then stop and look at the plugs.
