This is a weird problem:)Mate.Drain the fuel bowl.You may have got some water in there.Turn the fuel off.take the plug off the bottom of the bowl.Open the fuel tap for a few seconds and shut it off.Put the plug back in.See how it goes.I hope this helps.PS if there is water in the tank this may take a few tries to get it out..Afterthought!!Check that the drain hole for the sparkplug is not full of water.Its on the side of the head about level with the bottom of the plug.:)

My bike bike runs on main tank even on low fuel..it somtimes shows some missing. I think my reserve tank doesn't work.Any suggestions?


Check the reserve fuel line and the main fuel line to make sure they haven't been switched. I purchased a Suzuki Intruder and was riding all the way to reserve to check the mileage and when I ran out I couldn't start it even though I switched to reserve. Turns out that someone had the tank off to service the air cleaner and had reversed the two fuel lines so the fuel valve was running the bike on the reserve tank tube. so when I switched to the reserve position it was hooked to the taller brass tube in the tank and the gas level was already below it. The tanks just have two brass tubes, one taller than another so gas cannot be sucked below the taller tube when on main and then when switched to reserve it sucks from the shorter tube allowing the remaining gas to be used.

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!
cheers.

Wr450 09 no fuel in the carby bowl after dropping the fuel. i went to the servo filled up and then it wouldn't start.changed fuel put in new plug and dumped the fuel out of the bowl not much came out


Hi, Tony always check fuel flow first to isolate the problem area otherwise the usual suspects are:
1. Fuel tank empty.
2. Fuel cap or fuel tank not venting properly.
3. Fuel filter clogged with rust or dirt.
4. Fuel valve/petcock not in the on or reserve position.
5. Vacuum line to fuel valve cracked, broken, pinched, or missing*
6. Fuel valve/petcock clogged or diaphragm cracked, cut or torn*
7. Fuel line from the fuel valve to the carburetor or fuel pump clogged, cracked, pinched, bent, broken, or missing.
8. Fuel pump not working*
9. Fuel line touching cylinder or head causing fuel to boil and vapor lock, repair by rerouting and wrapping line with convoluted tubing.
10. Carburetor inlet clogged.
11. Carburetor float or needle and seat stuck.
12. Carburetor not venting properly overflow line or bowl fitting clogged, pinched, or bent.
* If equipped or applicable.
