Exhaust question?

[B1ToomeyYamaha]

If anybody can help, Well recently started getting blueish smoke outta my exhaust and a little bit of oil but more than usual and was wondering if it was something with the carburetor or the switch assembly on top of the carburetor wasn't sure if the colder weather was effecting it, any ideas?? But still runs like a champ and had the topend rebuilt a yearago.

colder weather will make it run leaner.. what does the smoke from your exhaust smell like?? motor oil( car oil) or your 2 stroke oil??? did you recently switch oil brands?? or pre mix ratio?

Its pretty strong smell kinda like motor oil ill crank up in the morning, I'm still using yamalube S2. It dont seem to smoke as much until it warms up.
