Sometimes, the easy solutions, are the best. Here are a few ideas. 1) Check your sparkplugs. Are they burnt? Are they gapped correctly? Are they the right plugs? 2) What kind of gas are you using? A lower octane fuel will not burn eficiantly enough, and could leave carbon deposits on the plugs.3) Check your air filter. After sitting for the winter, I suggest replacing the air filter, spark plugs, and engine oil, EVERY SPRING!

A backfire usually indicates a timing issue or having the wrong plug wire on a spark plug.

Motorcycle Question about a 1999 Suzuki Marauder VZ800 running rough after it is running a while.
Question edited for clarity and typos.

I had a similar issue on a Kawasaki Z1300. It was caused by a fuel line that was routed very close to the rear of the cylinders. When the engine heated up it caused a vapor lock, so basically a gap in the fuel delivery. Backfires can also be caused by weak fuel delivery.

1990 ford bronco idles fine when you accelerate the gas loses power and backfires through the intake
Fuel delivery problem, not enough fuel on acceleration could cause backfires. Many things cause backfires, mechanical and electronic. I need more info to give a better diagnosis. Did the problem happen all of a sudden or has the vehicle been running crappy for awhile.

My 1997 ford thunderbird stalls, idles rough, backfires, and has trouble accelerating
it could be as simple as your spark plugs, they may need to be checked for proper gaping and also check to make sure plugs are installed properly, could also be your timing might be off, could also be the throttle position sensor, these could all be effecting the fuel to air ratio, I would start with the easiest problem 1st......hope this was of some use to you.....

Changed all my sensers,fuel filter,cat. converter and intake gasket car still idles rough. Any other sugestions?
Are you sure all your cylinders are firing? If one or more isn't, then you would get a rough idle and cut off and possible backfires on the top end.

I have a 2007 Midnight Venture. It idles extremely rough (seems to be on 2 cylinders)spits and backfires even when warm except when the choke is on. Low end torgue seems to be missing. It also backfires...
Your primary jets in the carbs are clogged. (FYI- each carb has three metering jets, a primary, the needle or butterfly and the main jet. Each jet has an RPM area where it controls.) Simply blowing them out will not fix this problem. The carbs need removed and properly cleaned, the jets need to be probed and cleared then a new fuel filter installed to prevent it all from happening again. best wishes.

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 !!

Ron
