White/Blue smoke on startup IME indicates worn valve guides.

It is probably a silly thing to say however are you using the choke now the air temp is a little lower?

OR are you really in Canada and things are now warming up (less choke required)?

Also, is the blue smoke only when the bike is cold, or does it do it when the bike is warm too?

only smokes cold

Yup most likly guides or guide seals.

Quality or budget overhaul? is the question and were the guides re done and new valves fitted?
