winter rejet?
i decided to take the bike out yesterday, it was about 45 deg. outside. i noticed the bike acted much leaner even after a 20-30min ride on the highway and back roads, even got a couple of carb farts cruising at 60 mph. the bike has always ran smooth during the warmer temps is this the norm or do i need to adj. the carb?
carb has 45/180 jets 1.5 turns out on mixture plug, bike is stock sept for slipons.
what do you think?

If your slide vacuum port is drilled it could be giving you a drivability problem from the slide opening too fast and causing a momentary lean condition which would result in a pop back.

funny thing is that the bike came with a 185 main, which i thought was too rich.
it would just smell rich and it would start up with no choke, now it seems like maybe the p.o. had a reason for the 185 main jet. the original plugs were a nice chocolate color so now im thinking it was a mistake to goto a 180 main.

Run the bike through the gears into third gear and run third up to 60-70 MPH full throttle, then chop the throttle about 1/8 to 1/4 back and see if the bike either surges ahead or stumbles then recovers.
If it surges ahead, your jetting is lean.
If it stumbles and recovers , your jetting is rich.
If it makes no difference, you're pretty close
It should tell you something about the main jet size.

ya i did that already. at high speed its smooth, it just suprised me the other day in the cold 45 deg i got a couple of carb farts at 60 mph. 75 and 80 mph was fine. i think its just the cold air leaning the carb out. the bike ran just fine at 55 deg and higher.
