Bike Problem> HELP

I am posting this up for someone. I have helped out with what I could already over AIM.
Lets see if we can get some more thoughts into it.
__________________________________________________ ____________
I was wondering if you could tell me what would cause a bike not to start after not running it for 2 weeks(was getting it painted) it seems like it wants to start but wont, i put new plugs on it and cleaned air filter. also i tryed starting it while jumping it. It sometimes backfires and when you try to start it you can hear a click form the back of the bike. it did start yest and was idling at 300, yes 300 then when you tried to give it gas it stalled out. I dunno if i have the gas line hoses hooked up wrong? 2 black hoses to the petcock and a clear one to the back of the tank, i also have an extra black one but dont know where it goes too. please help

Here is a pic of the bike.

sounds more like a timing or vacuum problem...Time to check all the wiring and hose connections...maybe something got plugged or disconnected while painting

Or maybe the guy who painted it took it out and rodded the sh^t out of it and it slipped time.

It sounds to me like something in the carbs is gummed up. since its an EX500, I bet its the same sort of stuff mine is going through. tell him to look at his oil level, it may have gas in the oil, which will cause the backfiring thing, and the gas in the oil well, at least in my case made the motor so filled with oil/gas that it wouldnt start/run at all. if that IS the case, just change oil and filter, check your petcock isnt malfunctioning, and you'll be ok if the floats arent stuck in the carbs.

For a bike I didn't know, I would give it a shot of ether (starting fluid) in the air box and see if it ran for a few seconds. If it did, I would look at those lines to the gas tank. A vacuum line probably holds the petcock diaphram open to let gas flow into the fuel line to the carbs. Those two have to be hooked up right. The others are probably vent hoses.

this may sound really simple but i painted my bike and went out for a quick spin after painting. i let it warm up, then went down the neighborhood. right as i got to the main road it sputtered then stalled. i tried to crank it but it just wouldnt start. after much looking and testing at the intersection i figured my battery had died or something. so my buddy goes and gets jumper cables. i take of the seat and in the process picked the tank up to see if i had crossed lines or somehting. thats when i realized what was happening.... before i painted the bike when i got the tank off i turned the petcock to off...well you guessed it. i never turned it back on. check your petcock and see. if thats the problem then i feel so much better for my ignorance. at least i could help somebody...

The petcock is on, i just put a new battery in it and it seems like it wants to start so bad, it backfires once in a while now, also would low oil have any effect on the bike not starting

not sure now what to tell you. I've yet to have this issue now. maybe you can ask the people who had your bike EXACTLY what they touched, and how they hooked it up again.

Backfire? Are the sparkplug wires hooked up to the correct plugs?

You need to confirm you have the hoses connected properly.

Rarely is the question stupid, but sometimes the answer is you need to run everything you read online through your own personal BS meter to determine if it makes sense to you.
