YZ125 - carb overflow when lifting/maneuvering

[Lok47]

Is it normal for the carb overflow tube to leak a little gas when lifting and placing on a lift or ramp?  Or do I have a bad o-ring or seal for my float in the carb?  I'm pretty new to 2 strokes, but I remember this happening to a KTM 125 I used to own back in the day.

Could be a bad float needle/seat.

 

Could be too high of a float level.

I'm no expert, but I'm pretty sure the float level is set incorrectly or the float needle is bad/not sealing.  Check your float needle and set float height and you should be all set.  

My buddies KDX has similar issues but it does not effect anything with the bike running.
