I'm not sure I follow your question about the bike shutting off the gas in general. The stock carb has the fuel shutoff valve built into it, there is no external valve. So if you pull the stock carb completely off, you'll need to pinch off or plug the fuel feed line.
I put an external fuel valve on mine to be able to shut off the gas and service the vm22 carburetor without issue.
To make sure the fuel is ON, the valve handle is vertical. If you install the vm22 without a new fuel valve, then the gas will always be on. Makes it so that when you drain the float bowl to change jets, it'll drain forever until the tank is empty- clearly not what you want. Again, you'd have to either pinch off the line (which can damage it), or pull it off and plug it. Easier to use a $4 fuel petcock and just turn it off.
So yes, I'd get it all assembled, oil changed, levers and cables adjusted, valves adjusted, get it running and dialed in. Test ride it for at least a few miles and make sure she's copacetic.
THEN, go bawls wild on your upgrades. I'd still recommend changing only one thing per major system at a time, test and function check, then go onto the next thing.
Nothing sucks more than changing 10 things on the bike and then something doesn't work right and you have no idea where the issue is because you changed so much at once.

Thank you very much for the reply you answered all my questions and sounds good. That's an excellent idea about the fuel petcock I'm defiantly going to install one.
Any suggestions on what grade and brand oil I should use? Do I need to change a oil filter also? Also how much oil does the Boom Vader take?
I know exactly what you mean about changing more than one thing at a time, I unfortunately did that before with my BMW it makes troubleshooting things a lot more difficult. Thanks again for the info.
