Exaust Smoke From The Engine?
Ok my buddy is coming with a trailer but i wanted to start it up and after 25 sec i noticed exaust smoke coming from the engine area, Is it a bad carb? or like just gunk in it.

Could possibly have just been condensation in the engine/pipes burning off.
Or are you pretty sure it was smoke and not steam?

Did ya put any kind of cleaner or lube anything in there? Sometimes that stuff'll burn off - alarming, but not serious.

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...)

I did. but when i gave it a little amount of throttle the bike felt like it was dying. Then when i gave it more throttle the bike kicked and took off.
