Bike Doesn't start after taking it apart.

OK the bike was running ok. The problem I had was/is the choke would close all the way during long drives or short quick throttle burst. So after it closed when I come to a stop the bike would die unless I opened the choke or applied some throttle.

My Goal was to adjust the A/F screw, however not know where the screw was I pulled the bike apart assuming it was on the carb, which it is. I did not know that there was an adjusting screw down at the bottom of the air filter housing.

steps of what I did (remember bike ran before this)

Removed Seat
Removed Gas Tank (Petcock off)
removed air filter cover (saw fuel and oil in there. is that a concern?)
Removed air filter
Removed back of air filter housing from carb

No Adjustments made Re-assemble now

Attached the 2 air hoses at the bottom of the back of the air filter housing
Attached the back of the air filter housing to the carb (Carb looks like it could use a new o-ring)
put air filter back in
put the rubber gasket back in the air filter housing put cover back on
Put on gas tank
Attached electric from gas tank
put hose back in place at rear right of tank (if looking from the top of tank)
Put fuel line back on petcock and turn on petcock
Started bike

The bike ran very low idle for a few minutes then died. Now it won't start. does not seem to be getting fuel so I pulled the air filter to look at the carb I could smell the fuel could not see it spray though. (thought I would)
Put air filter back on.

now bike won't turn over like the battery is dead.

I am think about trying to jump the bike to see if it starts.

Does anyone have suggestion of what I can loook at or for?

Did you connect the little vacuum hose back up on the left side of the petcock.
Bike in neutral
kill switch off.
It wont get gas without the vacuum connected to the petcock. Still you are saying fuel line - there are two lines that go to the petcock. I may have misread your explanation. And you probably ran the battery down trying to start it.
On a 03 there is one hose - 04 and up there is two.
One on the left (small hose) is the vacuum.
One on the right is the gas line going to the carb.
If the vacuum hose is disconnected it will run for a few seconds and die the first time then it will not start.
Leaving that vacuum hose off is a common problem.
First glad it was something so simple.
If I were you I'd wait until you get Glen's permanent a/f adjuster - then it comes with a D tool to get that sucker out and that way you wont have to do everything twice. When you get it we can tell you the easy way of changing it.
Donut, I have Glen's permanent A/F adjuster and was going to change that out this weekend. If there is a trick or easy way of doing that like you mentioned, I'd appreciate learning about it.

You have to pull the tank and the airbox then there is a hose clamp behind the carb that you loosen then you cab pull it out of the rubber intake and up and will to be able to get at the old a/f under the carb. Glen's kit comes a removal tool that you can put into a screwdriver ( the type that has different driver attachments that plug in) Glen's instructions are pretty good. Make sure you get the old O ring out. (place a rag under everything in case you drop something). And spray the opening with WD40. When you reinstall the air box make sure you don't kink the big hose behind it on the bottom.

At 2 1/4 to 2 1/2 you should not need the choke. Is your idle turned uo enough it may be too low.
