Take the carburetors apart and either rebuild them or clean them thoroughly.

I had the same prob with my 97, It was not the head gasket but the O-ring on top of the head. Replaced the O-ring and has been running good for a year now with no backfire. Hope this helps.

Hi and welcome to FixYa,

Sounds like a very lean mix; confirm by checking the sparkplug tips. If the burn is very light brown to almost whitish, then it would be lean - too much air, too little fuel. Check for an air leak in the air filter box/enclosure. This would also happen if the air filter has been replaced with an aftermarket free breather (like K & Ns) or the exhaust has been replaced and no jettings done.

Postback results of initial checks.

Good luck and thank you for asking FixYa.

I have a 2004 Suzuki LS650 that won't start. Battery says it's charged . Has new spark plug. Gas is good. When I go to start it it does not start, and then the battery is low again.


You say the gas is good? do you mean fresh in the tank? Try draining the card floatbowl using the 10 mm headed bolt on the very bottom of carb. If you smell a foul odor there is varnish buildup in the carb which will require a complete fuel system/ carb cleaning to fix.

Overheating, motor out of step. Good idle speeds but when the bike is trashed!

I have a 1986 suzuki 650 savage the carb seems to have a problem. It started flooding gas coming out the over flow. I took it off and took the float cover off and replaced the needle needle set and float....


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.

Backfire wile deselerating were is the sparkplug


A bad spark plug is not the likely cause of this, a rich mixture or intake leak or exhaust system leak will. The spark plug is located under the gas tank. The gas tank must be removed to access the spark plug, do not use any pliers to remove insulator plug boot, twist it by hand and gently pull as you twist until it breaks free.

My bike wont fire


First put a nail in the plug boot and hold it close to the engine and crank it over to see if you have spark to the plug, if you do, pull the spark plug out and see if it's wet. If the plug is dry put about a teaspoon of gas in the plug hole and put it back together, it should run for a few seconds. If it does that you have a fuel supply problem. It may have a fuel shutoff valve inoperative, or a carburetor problem. If you have no spark to start with and the plug is wet with gas, you have an ignition problem. If the exhaust smells like gas you are probably getting lots of fuel, but the spark plug can tell us lots of things. A new spark plug probably won't hurt either.

Need to change spark plug and do not have manual...how do i get to the plug...also backfires when i shut it off


pull the gas tank off to get to the plugs, be very careful pulling the plug wires loose, they are easily damaged, as far as the backfiring goes is the idle speed to high?

Hi there!
Too much gas mixture or there maybe plug problems. If it doesnt start, charge the battery and start the bike with new spark plugs. Replace the plugs, this usually works.
Let me know if this is any good. Other options:

1. THe spark plug cable
2. The ballast
3. The jets are clogged
4. Poor fuel quality.

Gas problems


The flow bowl is stuck. Easy to fix. Take the carb off and take it and dump it unside down. Re-install and check it out. Or you can try to tap on the flow bowl on the carb. Float bowl is on bottom of carb, it is screwed in by 4 screws.
