The description fits with a lean air/fuel mixture; more air than the amount of gas that is going to the engine really needs. With the laws Congress enacted several years ago, the only people who are supposed to be working on anything that can affect the air/fuel ratio of our motor vehicles are the certified mechanics trained to perform that kind of work. (Thank you, EPA.)

The official recommendation is to take the Suzuki to your local Suzuki dealer. Sorry.

1998 Suzuki VZ 800 Marauder running on one cylinder


Hi, Michelle you need "FIVE" things in order for a cylinder to run properly:
1. FUEL: in order to validate your not getting fuel spray some starting fluid into the air cleaner and hit the starter button, if it fires up and runs for a few seconds then you know you have a fuel delivery issue. Multi carb banks should be bench "SYNC"
2. SPARK: remove the spark plug and with it connected to the spark plug cable ground the threads to something metal you should see a bluish white spark if not you have a faulty spark plug, spark plug cable, ignition coil, condenser, CKP, ECM, sensor or the wiring in between.
3. COMPRESSION: you must have at least 80-100 PSI for most bikes, multi-cylinder engines should be within 10-15% of each other if not perform a leak down test you may have a burnt or bent valve or hole in the piston or broken rings.
4. CAM TIMING: confirm your timing marks are aligned to see if the cam chain or adjuster are worn out and the chain has skipped a couple teeth.
5. IGNITION TIMING: on older bikes check to see if your points have not closed up, timing plate has not become loose and confirm with a timing light for proper retard and advance functions, on newer bikes where timing is controlled by an ECM and is nonadjustable check you CKP, TPS, MAP, O2, sensor or its counterpart for integrity.

Vt1100c2 backfires through pipes on deceleration - hesitates on accelerating. It runs fine at highway speeds. Seems to throttle down slow.


Could be running too lean, check the color of your plugs to know for sure, black and dry is rich white and blistered is lean.,

Constant backfire on deceleration 88 chevy 4.3 V 6


Check for exhaust leaks. Esp Leaks toward the front of the car. Hold your hand over the tail pipe using a rag and see where the loud hissing noise comes from. Repair the leaks and I bet the backfiring goes away

Good Luck
