squeezing left brake handle causes scooter to shudder/vibrate

[spikebites]

is this normal? or has anyone else experienced this?  This only happens when squeezing the left brake, the right side is fine.  I only notice this when I am parked at a red light and squeeze the brakes... I think this also happens when the bike is in motion, but I can't tell since the bike is moving.

Should I be worried or is it something I can fix myself?

Every scooter probably does this ...you are feeling the vibrations from the engine and rear tire relationship. Hold the front brake....you are at the other end of the scoot, away from the engine...=== no engine vibrations.
Nothing to worry about. If you don't like this feeling at a stop light...hold the scooter steady with the front brake instead.
