If you just got done working on her. I would bet it is just something got on the exhaust or other engine part that gets warm. Let her run for a good 5 to 10 min and see if she still smokes after that. After I did my stator change I had smells and smoke coming of Angel for 5 to 10 min. Now it's just a minor leak from around the outer housing. (I should have used some RTV!)
Ya I am sure it was exaust smoke cuz i could smell the gas inthere. I havent put anything in there Like lube or anything, and I havent worked on her recently. Could It be a blown head gasket? My compression was 150 on the front cylinder and 135 on the back?
25 seconds is hardly a way to tell if somethings wrong with the bike.
Go for a ride - see if she's still smoking when ya come back (you say "noticed" so I assume it wasn't a huge amount of smoke). If the bikes running fine a little bit of smoke at startup isn't a huge deal.
If ya pay attention, many vehicles put out a little bit o exhaust smoke now and then (mine does - haven't tracked down why...)
