I have a 2001 sv 650 it sat for a year i cleaned the carbs out and it till will not start it has a brand new battery

solenoid or relay stuck, if water has managed to get in over the 2 years or its corroded up the connections will connect, when the power went in the first time it moved but is unable to go back into the original off position.

Sounds like the carbs are gummed up from the old gas sitting in them. Remove the carbs, disassemble, clean with a carb cleaner, and reassemble.

check and clean carb, try a lil carb fluid in carb to fire, also check the usual things for a tune up: cap & rotor, wires , also if its sat for a year add some clean fuel, condensation in fuel tanks and lines will wreak havoc, and will clog even brand new fuel filters

Sounds like the carbs need to be disasembled and cleaned. Make shure you clean all jets and readjust the float. the air/fuel screw will be 1 1/2 turns out from seat.

yes buddy the idle screw is too low on carb is a screw idle screw turn this in 1/4 of a turn at a time till it idles at 1000rpm or it dles ok

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.

you will have to clean the floats in carb and blow out the jets. Wouldn't be bad ideal to get new needle and seat.

check ground and kill switch and ignition switch connections

put in new spark plugs

Remove the carb , dissemble it and clean the varnish out. After so long in storage I am surprised it runs at all. Remove the petcock, ( gas valve ),water trap and clean it out. Next let one cup of gas flow into a container. Any water or rust in the bottom of the container? If any rust was in the water trap or the container then purchase an inline fuel filter to eliminate the rust getting into the carb.

If cleaning the carb yourself does not do the trick then take it to the dealer and have them clean it and install a carb kit. This should get you back on the road.
