If it is backfiring the timing is set incorrectly or the spark plug wires are not connected in the correct order.
Rev the engine six or seven times before coming to a complete stop. Rev it all the way to the edge every time you stop.
Backfiring is a sign of improper ignition timing.
well if its a 2 stroke it needs new reeds if not, your timing is prolly off a bit
More than likely you have a exhaust leak.Check the headpipe seal
Backfiring it normally caused by a car that is very badly out of time. It can also be caused by the spark plug wires being connected incorrectly. Switching to a higher octane will not help at all.
NO, but a good tuneup will probably cure your problems. There is no cure in a can for the symptoms you list.
"Backfiring" is the present participle of the verb "backfire", to fail in a manner to bring about further misfortune.
Backfiring is caused by incorrect timing, or plug wires installed incorrectly which messes up the firing order. Make sure your plug wires are installed correctly. Can also be caused by an overly rich fuel air mixture.
If it is backfiring only when you kill the engine, allow the engine to idle a few minutes before you kill it. If it is backfiring while in use, check the intake gasket and bolts for wear or looseness.
if it only backfires when shutting off, usually this means its getting to much gas!! if it backfires will running adjust carburater.
Hey John==Without knowing what you have, it is strictly guessing. Check the firing order. Make sure the compression is ok on the engine. GoodluckJoe
To prevent backfiring make sure the belt is tight and in good working order. Also clean the air filters regularly.
Probably. Backfiring is a symptom of a lean condition. Wouldn't want to leave it like that.
Backfiring in any motor is either badly out of time or a burnt valve.
Needs a tune up
no. it ended up backfiring on them
advance the timing a little.
Change the pipes for Screamin' Eagle slash cuts. To stop backfiring you will need to fit venturies in the headers and then get the bike Dynoed for optimum performance.
yup it is more likely to break down well if its backfiring that's not good that can mean there is some seriuos internal problems
The backfiring is due to leaning out the fuel mixture. You can richen up your carbs a bit either by turning the idle mixure screw, or it may require rejetting your carburetors.
Exhaust leaks close to the engine.
