SOURCE: my honda cbr 600 wont start and keeps backfireing

Check your plugs. If all four are sparking then your carbs are out of sync. They will need to be re-balanced.

If you are capabable in doing this job your self, you will need a screwdriver that fits your adjuster screws and a CarbTune Carb balancer.
Remove your tank and airbox.
You should see the flaps inside your carbs. These should open when you move your throttle.
Start on the outside carbs to get them balanced with the 2 centre ones.
To start, unscrew the adjusters all the way out. then screw them in until the 2 outer carbs move at the same time as the inner 2 carbs
Once this is done then adjust the centre balancer to syncronise the 2 left hand carbs to the 2 right hand carbs.
Now if you have done this correctly, all four carbs should open at the exact same time.
If you have a Carbtune balancer, remove the plugs from the top of your inlet manifold and plug in the hoses from the carbtune balancer.
Start the engine and adjust the screws until the weights inside the Carbtune balancer all read the same.
Once done, remove the balancer, replace the plugs into the inlet manifold, refit the airbox and tank and it should run so much better.

If your not 100% confident to unertake this job yourself, take the bike to your local dealer and ask to have the carbs balanced.

SOURCE: How much oil does a 2000 honda cbr 600 engine hold...

Generally any big bike can hold up to 3.5L oil with filter change.
Rule of thumb when changing oil and filter is to fill the crankcase with about 2.5 - 3L oil and check dipstick on oil filler neck for indicator as it's normally marked high and low (max or min oil) that cn be in crankcase.
If good enough and answer your question just give a 4 thumbs up. Thanks

I have tried to start my CBR 600 F up,its turning over but not firing up, but it has been stood for a year & I've just put a new battery on it,what do I do next


Have the carburetors or throttle bodies & injectors cleaned, clean fuel lines replace all fuel, change oil to be safe.

Spark plugs


If the lights won't even come on, the spark plugs are not the cause of that problem.

Make sure the battery cables at the opposite ends from the battery are connected tight and corrosion free.
Check that all the fuses are good.
For some reason the power isn't getting from the battery (if it is in fact charged up) to the electrical circuit (blown fuse, loose/disconnected wire, etc).

1987 Honda CBR 600 F Hurricane no spark


Hi, Anonymous and the usual suspects are:
1. Fouled spark plugs.
2. 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.
3. 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.
4. Loose connection at ignition coil or plug between ignition sensor and module.
5. Spark plug cables in bad condition, shorting/leaking, spark plug cable connections loose check for spark leakage in the dark.
6. Faulty ignition coil or electronic control module.
7. Faulty pulse coil.
8. Faulty CKP, CMP, or BAS sensor.
9. Faulty ignition switch.
10. Tilt sensor needs a reset.
11. Security alarm failing to disarm needs reset

It sounds like the starter relay is getting lazy on you. Double check that the plug in connector is making contact through it. And double check your fuses. The starter relay has internal switches for both the ignition power and the high power connection for the starter motor. I don't think it's maintaining the ignition power for you.

I have a 1997 honda CBR .. I put two new spark plugs in it and just bought a new battery and it will not start up! It just backfires when you crank it up! The battery is fully charged. I don't know what...


Have any more details?

How long has it been sitting? How old is the gas? Have you checked that your are getting a spark from the plugs? Gas turned on?

Cheers,
