Cylinders are numbered 1 to 4 going from left to right, as you would see them when sitting on the bike. The left hand Ignition coil fires cylinders 1 and 3, and right hand ignition coil fires cylinders 2 and 4. Check to make sure you are getting spark on all cylinders.

No! No! No!

Left coil is cylinder's 2+3

Right coil is cylinder's 1+4

Strip the carburettor's, blow through the jets with an airline and use fresh fuel.
If you fuel tap has a 'prime' position put it there until you have ridden a few miles.

Bike is starting and backfireing,cant give any gas or it will die. this is be couse of lack of gas fro secondary ?


Hi, Michael and the usual suspects are:
1. Severely discharged or a damaged battery, should have 12.5 volts or better and be able to pass a load test if necessary.
2. Check battery terminals for damage or corrosion, check the battery cables at "BOTH" ends for loose, corroded, or broken connectors, "INSIDE" and outside the cable harness, perform connector wiggle test and check cables with an ohmmeter if necessary.
3. Faulty main circuit breaker and or connections.
4. Faulty ignition coil and or connections.
5. Faulty spark plug, oil or gas fouled, wrong heat range or service type, wrong gap, loose in the cylinder head, broken electrode or insulator.
6. Faulty spark plug cables, leaking or broken, internal damage check for spark leakage in the dark.
7. Faulty ignition module, switch, CKP, MAP, CMP, sensor and or any connector in the ignition circuit could have corroded, loose, or broken pins/sockets
8. Burnt exhaust valve or air leak in the exhaust system.

Strange noises and wont stay running


The clunking is probably just the kick back from the motor. You're hearing the compensator assembly doing what it's supposed to do.. Which is saving your crank. The whoosh sound ?? could it have been a backfiring while you were trying to start it? Once you ad stabil to the fuel and it gets in the system it will run terrible until the stabil is completely run out of the system. If you're wearing the battery down trying to start it, it will cause the kick back and backfiring through the carb too. Make sure you have your battery fully charged before trying it again.

Its a 1998 528i bmw that will start but wont stay running also there is a loud kind of backfire noise from one of the cylinders . the engine wont rev up proper even though i keep pressing the throttle...


The fact that you have a backfire noise that you can trace to just one cylinder makes it sound like a spark plug could be loose or broken. Pull out your spark plugs and examine them. On a '98, that eill mean pulling off the plastic cover, then removing the coils (need a 10mm socket, be careful with the ground wires) and then reach down in with a small spark plug socket on a long extension.
Also, look for a massive air leak on the intake. Take apart the air tubes from the air filter up to the throttle body looking for air leaks. You could also have a leak at the intake manifold gasket but you may need help to check for that.

1992 Suzuki GSX-R 750 Will not start only backfires


Hi, Angelarny and the usual suspects are:
1. Severely discharged or a damaged battery should have 12.5 volts or more and be able to pass a proper "LOAD" test if necessary, you may have a preliminary reading of 12.5 volts or more but little or zero amperage the battery is faulty and must be replaced, AGM batteries fail in this scenario more so than lead acid batteries.
2. Check battery terminals for damage or corrosion, check the battery cables at "BOTH" ends for loose, corroded, or broken connectors, "INSIDE" and outside the cable harness, perform connector wiggle test and check cables with an ohmmeter if necessary.
3. Faulty main circuit breaker and or connections.
4. Faulty ignition coil and or connections.
5. Faulty spark plug, oil or gas fouled, wrong heat range or service type, wrong gap, loose in the cylinder head, broken electrode or insulator.
6. Faulty spark plug cables, leaking or broken, internal damage check for spark leakage in the dark.
7. Faulty ignition module, switch, CKP, MAP, CMP, sensor and or any connector in the ignition circuit could have corroded, loose, or broken pins/sockets
8. Burnt exhaust valve or air leak in the exhaust system.
9. Cam sprocket loose and has jumped a couple of teeth.
10. Loose or worn out cam chain or tensioner.

1998 bmw 528i severe misfire


If you've never replaced the timing belt or chain,That would be my first thing I'd check is the Timing belt or chai, just aline the timing marks on crankshaft and then look at the position on the distributor to see if it's pointed in the #1 firing position .
