this morning after riding her to work, I started the engine for around 15 or 20 seconds and then shut down. The I tried to start it again right away and it just cranks. Do you guys think I flooded the engine?

Turn the key on/off and try again
if that does not work open/close the throttle a few times before cranking her over
if that does not work try to give her a little throttle when its cranking over
If that does not work walk away and try later

Although in my case it was always after it was already warm, and sat for a little bit.

Yeah, 15-20 seconds tends to piss 'em off. Either use the plug clearing technique, or you can try to start it with about 1/4 throttle and see how it does.

What is the plug clearing technique Ratbuell?

Hollon...grabbing a manual...

OK.

SPARK PLUG CLEAN
Automatic
Starting the engine without running it up to operating temperature can foul the spark plugs. To execute a spark plug clean, the ECM rapidly fires the spark plug up to three times without enabling a start.

The ECM records the number of starts without running up to operating temperature. After five starts without running up to operating temperature, the ECM will automatically execute a spark plug clean before starting the engine.

Manual
If fouled plugs are suspected, a spark plug clean can be initiated manually. Repeat the following sequence three times:
1. Roll and hold the throttle wide open
2. Turn the ignition to ON
3. Wait three seconds
4. Release the throttle grip
5. Turn the ignition to OFF

even better idea, works everytime.
Pull the seat off, pull the fuel pump fuse, hit the start, it will burn off any excess gas without adding to it. when you are sure the gas has been ignited and burned off, turn key to off, put fuse back in, and start normally. I have found it helpful to take the slack out of the throttle just a hair when starting to keep it running. I usually start my bike in the morning when its less than 29 degrees outside, which happens to be where the bike is too. I have to hold the throttle open just a hair to keep it idling. I've had the bike 1 month, the shop has had it more than I have for various bugs. I have 1100 miles now and it seems to start a little better without assistance. Maybe because its 34 degrees now

My fuel pump locked up and if you did not give it gas trying to start it then this might be the problem,

I never touch the throttle unless it is to go.

There is no excuse for a brand new motorcycle that will not start.

I am reminded of the starting drills that one had to use to fire up British singles & twins 40 years ago!

Well, you don't have to tickle the Amal...

The 1125 doesn't like to stay running when it's new and cold.
Dunno about warmer climes, but that's why I was flooding mine in the beginning, trying to give it just enough gas to keep running.
After a thou or so on the clock, it's a total "push-button".
Like Mike said, only use the throttle to GO.

Wait for the red light to go out(fuel rail is pressurized) and push the yellow button.

Mine has 2000 plus miles on it here in Florida. Since new and still today when cold...starts up with no throttle, dies...relight and stays running.

Once up to temp, restarts are always one hit.

I only hit the button, never any throttle...properly mapped efi shouldn't require throttle angle input...that is what an idle air motor is for...

...can't explain the two hits needed cold unless the cold start map is in fact...a little off.

Slypiranna try waiting to all the lights go out and then start,

it take a few seconds for the fuel pump to come up to pressure,

I live in MA and use to take me to hits of the button and now I wait and starts every time first time.
