Default wont start and pic requet

Well i cleaned the carbs and put in the ngk plugs and it still wont start.

its getting spark to all 4 plugs just no fuel now.

i read the manual and there is a lot of different things it could be but i was wondering if anyone knew where to start with it?

also the hoses that go from the tank and carb if i can get a pic of those.

does the big hose from the carb go with the other big house or the little skinny hose?

There are two hoses running from the fuel petcock. The small skinny one runs up the left side of the carbs and is a vacuum hose which allows the fuel to flow. If it ain't connected, def. no starting.
The big fat bugger is your main fuel line and runs around the right side rear of the tank, to a T-piece on the carbs, where the fuel will run into the carbs.
Take the small skinny one and suck on it with the tank connected. Fuel should flow into the carbs, and it'll start. Maybe the diaphragm in the petcock's buggered.......[X(] Repair kits are available......
If no-one's got any pics, I'll take some for you.

what ever you do DON'T SUCK ON THE BIG HOSE!! taste of gas stays in your mouth for a week .
+1 for shadow
I would test the petcock while its disconnected from the carbs...when you put a vacuum on the little hose the big one should flow fuel. if thats working the carbs are next.

+1 shadow, the little one from the petcock should be hooked to the vacuum port on #1. If it is cracked the bike will not get fuel. If you or a friend have a brake vacuum-type bleeder tool, you can use it to open the petcock by hooking it up to the small hose and drawing a vacuum. If you don't get fuel, the petcock is clogged.

"Little black Box" ....?
The two hoses go in different, opposite directions as mentioned above.
Are you referring to the fuel petcock under the tank ?
(doesn't look like a little black box on my bike, it's a big metal tube coming off the bottom of the tank with two/three tubes which run off it)
