so my new 03 919 runs and starts fine. Warms up to normal heat on the temp gauge but when I am running down the road at 45 F the temp drops down to barely registering. when I first rode it it was cold out 28F but even at 50-60f it runs cold. stuck open thermostat? any idea what thermostat it would be?

A great bike to have!
Perfectly normal for a 919, although I'd expect the needle to be at least a tad higher @ 50 -60 F ambients at low power levels. And if you live in a damp area, the humidity will cause the bike to run a touch cooler for any given ambient.
Also, counter to a stuck stat possibility is the fact you can even warm it to the normal temp zone before it starts to drop once riding a bit.
You can remove it and check it on the stove in a pot of water if you want to be absolutely sure.
If you have concerns that the thermostat isn't closing completely it's an easy task to remove the thermostat and check if it's working properly. All you need to do is prop the gas tank up and drain some coolant in order to remove the thermostat. Just a visual will tell you if it's not closing and then, as mcromo44 said, just a thermometer and a pot of water on the stove will tell you at what temp it's opening and closing. The service manual shows this in detail.
A hint - I'd wait till the wife is out of the house to do the 'pot of water on the stove using a cooking thermometer' thing.
Been riding mine to work in the morning and it does the same thing. Only time it jumps up is if the temp outside is 70+. Cool running bike and I love it, my gixxer used to scare the crap out of me for running close to the top.
