SOURCE: i have a 99 vz800 suzuki back firing when i decelerate

Hi and welcome to FixYa,

In the versions we have worked on, almost always, your description indicates too lean a mixture on at least one of the carbs (chances are the one for the front cylinder). Considering that it has not been used for over a year, the carbs would need to be pulled down and cleaned. Old/stale gas would have coated the inside of the carbs with varnish like substance. This would be blocking the ports, holes, jets, slides and definitely, the bowl, walls and floats. Other than the above, the fuel pump/regulator would also have to be considered.

Incidentally, I was made to understand that certain versions has had known issues with the carbs and a recall was done.

Good luck and thank you for using FixYa.

SOURCE: backfiring on deceleration from exhaust pipes

May be running too lean or too rich. Check the color of your plugs, black dry and sooty means they are rich, white with blisters lean.

SOURCE: backfireing when decelerating

it can be caused by a number of things including.
lean mixture--air leak intake or exhaust,
leak in exhaust gasket
low ignition voltage- bad plug,lead\resister cap
tight valve clearance
and a number of less likely problems like faulty kill switch, ignition switch\cable connecter,igniter.
If it is not the standard exhaust, the jetting may need a slight change

So first give it a tune and service, check valve clearances,new aircleaner, drain carbs, tighten exhaust bolts and clamps, intake clamps and bolts,it may need exhaust gaskets

Engine missing is a vast subject and calls for number of things to examine. What are the problem symptoms? Is it concerned with one or more of the following?
- Rough idle, stalls or misses.
- Engine hesitates/ poor acceleration.
- Engine diesels (runs after ignition switch is turned off).
- Muffler explosion (after fire) on deceleration only.
- Engine backfires.
- Engine rattles at idle speed only.
- Engine rattles at all speeds.
Please mention if there is some other symptom.
Thanks.

Backfiring and miss in ford 4 liter


Hi Dwight, It would help to know more about your problem. What vehicle are you referring to? When does the backfire occur, during acceleration, deceleration, at a cruise speed, at idle? It would also help to know what vehicle, what engine and what fuel type? Regards John

Backfireing when decelerating


it can be caused by a number of things including.
lean mixture--air leak intake or exhaust,

low ignition voltage- bad plug,lead\resister cap

and a number of less likely problems like faulty kill switch, ignition switch\cable connecter,igniter.
If it is not the standard exhaust, the jetting may need a slight change

So first give it a tune and service, check valve clearances,new aircleaner, drain carbs, tighten exhaust bolts and clamps, intake clamps and bolts,it may need exhaust gaskets

Backfire through the intake at cruising speed, or idling, also backfire through exhaust when decelerating Runs fine during hard acceleration. Thought it was water in fuel, but dry gas did not solve the...


Intake:
Lean, or spark control problem, valve problem, bad fuel, plugged carburetor.

Exhaust:
excessively lean or rich with exhaust leak, valve problem, spark control problem.

Check valve clearance, as vlaves wear the gap closes, most riders don't bother to adjust them till they have a problem like this.... By the way the valve may be part of the issue for backfiring while deccerating but Pipes cause this.

Backfires during deceleration


Check a spark plug for color. A white plug means that it's too lean (Not enough fuel) They will pop when lean on decel!
