Default Jerks and jitters

The bike starts fast with choke on but needs to warm up a bit. Runs well and smooth but when I release the clutch the bike jerks and jitters until it gets up to speed, than it runs well as long as Im going 10 15 MPH

When I reach a stop I pedal a bit to get it to a decent pace than back to the jitter for 1-2 seconds max

Is this normal?

1) 20-1 mixture with synthetic
2) Boost bottle
3) Bosh plug and boot with .038 gap
4) Everything seems tight no noticeable air leaks
5) performance exhaust
6) Mount is rock solid- leaded handle bars
7) 20 total miles
8) Max speed was 28 MPH for a couple of seconds... not hot rodding

Any thoughts?

On a side note... Should I be using regular or r premium gas?
