SOURCE: 1981 Suzuki 750L. Wont start properly

Sounds like the battery you have in the bike has gone bad sence you have to jump start it all the time. And yes the bike will run bad cause the cdi need a good voltage to work correctly. Get new one and put in new asid in and put it on the charger till it is fully charged and you should be good to go.

SOURCE: backfiring

Check the chassis wiring whe it enters the side cover on the ignition side of the engine. There is supposed to be a rubber grommet there. Soetimes that grommet gets kicked loose where is comes out of the side cover hole and the wires chafe to the point that they ground out the ignition module.

Also looks for bare wires under the gas tank around the ignition coil module. Everything your describing points to a chassis short to ground.

Also the problem can be in the handle grip with the kill switch or a bad kill switch.

It is probably time to break out the Ohm meter and start chasing wires.

SOURCE: backfire

Your plug may be firing in a fouled area. When I have a problem like this, I 1.change the plug. 2. Take the carb and have it cleaned in a sonic bath and my honda dealer(They are the only one with this cleaner in my area) for about $25. 3. Check to insure that the fuel mixture screw is set correctly(about 2.5 turns), and 4.clean the air filter or replace it.

SOURCE: slowing down going into a turn my bike backfires

Some people call this a ""cough stop"" assuming the bike is well tuned and nothing else is wrong ,
I use an upper cylnder lube in my wr450f called Moreys and it solves this, it also helps it start easier, I cant explain why, might not work for everyone, but its a cheap solution, hope it helps.

Backfire on 2010 flstc?


Backfiring is caused by a lean air/fuel (A/F) ratio. A leaner A/F ratio takes longer to burn and will continue to burn in the exhaust, hence the backfiring. Is the bike stock, or have you changed the air cleaner or pipes? Both of these changes will result in a leaner A/F ratio. HD bikes with fuel injection already run lean to meet emissions requirements, so changing pipes, etc. will make the problem worse. If you have not made any changes to the bike, make sure that the fuel system is clean and you are using good quality gas. You can also have the bike's computer (ECU) remapped to run a little richer. Your dealer may be able to do this for you, or there are aftermarket ECU tuners available for your bike that can adjust the fuel map and ignition. These will give you the added benefit of more power and a cooler running engine.

I bought a bike that wont turn over and is backfireing what chould the problem be?


Hi It may be excess fuel form the non starting that is giving you the backfire! Change the plugs (if necessary) or at least visually inspect the plugs for sooty deposits and dis similar coloring and condition.Backfiring is almost always a timing issue ! Good Luck

Why does my 1998 gmc truck backfire and stutter sometimes stall when driving


I would suspect a burnt valve. An engine compression test will verify this.

Yz 426 wont idle, backfires and bogs out


Hello phwolfe,
Did not backfire but , boged out appling fuel. Found it was flooding because
the floats were over filling the chambers. Adjusted float settings (by eye )
problem solved !! Keeping the chambers 1/2 to 3/4 full worked for me.
My Bike is a 1983 Midnight Maxim 653cc. 4 Cylinder. Maybe yours is fuel injected ?

Best of luck !!
