Maby the old owner cut the pickup tube and you no longer have a reserve.

    Sounds like the gauze filter on the end of the reserve tube is blocked

2005 Suzuki DRZ 400 S quit running

Hi, Aiden and the usual suspects are:
1. Severely discharged or a damaged battery must have 12.5 volts or more and be able to pass a proper "LOAD" test if necessary, you may have a preliminary reading of 12.5 volts or more but little or zero amperage the battery is faulty and must be replaced, AGM batteries fail in this scenario more so than lead acid batteries.
2. Faulty alternator/generator and or voltage regulator.
3. Loose or corroded battery terminals and or cables especially the "NEGATIVE" cable, look for loose, corroded, or broken connectors inside the cable harness at "BOTH" ends.
4. Faulty main circuit breaker or ignition switch, check for loose connections and continuity.
5. Faulty system and or ignition relay, check for continuity.
6. Faulty ignition coil, ignition/electronic module.
7. Faulty CKP, CPS, CMP, MAP, TPS, or BAS sensor, corroded, loose or broken wire connector pins/sockets.
8. Throttle cables and or idle speed improperly adjusted hot idle speed should be 950 RPM to 1000 RPM.
9. Faulty neutral, side stand or clutch lever safety switch.
10. Fuel tank empty
11. Fuel tank contaminated with ethanol sludge.
12. Water or dirt in the fuel system, or clogged filter.
13. Restricted, blocked or kinked fuel line.
14. Faulty fuel pump.
15. Faulty pressure regulator.
16. Faulty or clogged fuel injectors.

Fuel tank reserve capacity

Hi Kumud:
On my KLR 650 the reserve is 0.9 US gallons.
There's really not much point in worrying about "non usable" amount.
What I would recommend, especially if you're going to do any remote riding, is to strap a spare gallon (or 2) to your bike, then go for a ride. When you run out of gas, reset the trip meter to zero, turn on your reserve, and ride until you run out of gas again.
You will now know how far you can go on your reserve. That's the first important part.
Now put you spare gas into the tank and ride off to find a fuel station. Fill the tank, set the trip meter to zero, make sure the fuel selector is set to "ON", and go for a ride until you run out of gas again.
You will now know how far you can go on a full tank before you have to rely on the reserve.
If you use this system it won't matter what machine you have, and depending on your riding technique, the distances will vary.
Gotta love riding!

Reserve tank not working

Are you turning the tap the right way as it sounds like you are running on the reserve tank all the time and when you turn over the tank is already empty.

No fuel to carbs

turn your fuel tank petcock to 'reserve'.
the fuel is fed thru a vacuum valve (opens to allow fuel to pass when running or turning over). fuel is delivered via gravity otherwise (tank is higher than the carbs).

Reserve fuel tank question...

Check that fuel valve, pull out that output fuel hose, turn the valve to "reserve", if fuel flows, that means it works( fuel valve ), if no fuel flows, that valve has STUCK valve flow.

Most bike problem is in that fuel valve.

Hope that helps!

My xjr1200 fuel petcock reserve is not working. when the tap is on it runs the tank dry without the reserve kicking in to action.

when the tap is in the down position it will only use fuel up to the reserve and you will need to turn the tap up to put it onto the reserve fuel.

Change the fuel filter, check the fuel pressure, then pull the tank and replace the pump if the pressure is below spec.
