I have a 2001 suzuki sv 650 s, it starts easy but when the motor ran for a while it just dies.an when i try to start it again only the lights go on.is there a mis connection or what should i look for

SOURCE: bike wont start

I posted this for a similar problem, maybe it can help. Are you sure it's getting gas to the carbs? Some people don't realize the 99-02 SV650 has a vacuum-actuated fuel pump, and sometimes it can get stuck. Mine has had this problem, and it took me a while to determine it was the problem. I would guess it only happens after the bike has been sitting a while (ours unfortunately sat for a year or so without being run).

Best way to check it is to lift the tank (it's bolted to the frame on the right side of the engine just under the tank). Unplug the line toward the front of the motorcycle from the fuel pump, and connect some spare fuel hose to it running to a can next to the bike (don't want to get gas everywhere!). With everything else still connected, crank the bike for a short period to see if any fuel comes out (shouldn't take long). If not, then move backward and ensure fuel will flow from the vacuum-petcock when the bike is cranked. If that does work, your fuel pump needs some work. I was able to take mine apart and unstick it.

If the starter has stopped working then no there is no way to bypass the bendix on the starter. Sorry

Yea these carbs can be a real pain sometimes to get right. First thing you need to do is varify the float seat is working and totally stopping all fuel flow.... and all the jets, main, pilot and choke circuit are absolutely clean. Bench test the float needle valve by connecting a hose to the carb fuel line nipple and letting gas gravity feed as it would in a run position. if it tests ok, remount it on the bike...
i'm guessing you have a vacuum petcock on this year model? If you do, it needs to be inspected.
In the "on" position you should have no gas flow coming through the petcock, In the "prime" position it free flows. If there is a hole in the diaphram the engine will **** gas and not air (vacuum) through the hose and it will flood. If you don't have a vacuum line on your petcock then it is a different kind. Be sure to check your crankcase, it could be way past full with gas that has entered, dont start your engine like that...drain it all out. make sure the air filter is dry. You will have to replace the spark plugs...a gas soaked plug won't fire.
Good luck, i hope this helps.
