Have 150cc water cooled scooter sometimes smokes for a second in start-up. Could this be the head gasket? Any suggestions?

what color is the smoke? white is usually coolant but can sometimes be slightly rich and give a white or slightly grey/blue/black too. oil is generally blue smoke. typically valve seals or in the headgasket.

How can I see if it's the head gasket for sure?

the only way to ever know whats going on in a motor for sure is to open it up. but if its just super brief and not giving you a running issue or losing coolant or oil i wouldnt bother as it could just be nothing. you could even just have worn piston rings or carbon buildup as both of those can make a motor smoke too. though carbon buildup is usually seen smoking during wot.
