Check all the wiring on and around the coil make sure theres a connection between the coil and the sparkplug and last check to see if your coil is working perfect

Good Luck.

SOURCE: CRF 450 IS LEAKING OIL TROUGH CARBURETOR

Hi there

You should not have oil leaking from the carby. If you have over filled it with oil, then it may be coming from the crankcase breather and then into the airbox, and appearing to come from the carby. If you have not over filled it, then the bike may have blowby problems with compression gasses passing the rings, and in a similar manner forcing oil out the crankcase breather. Not sure about the hole in the side of the cylinder... do you have a picture? Unless its pouring out, or gets worse, I would not be too worried. If you have over filled the oil, maybe time for an oil change to get the level right.

regards
robotek

SOURCE: 06 CRF 450 that went under water, not getting fuel to plug

Chances are the air filter is extremely wet. Air can't get through a wet filter, and if no air can flow through the carb, no gas can flow through either. Remove the filter and try again to get the engine started. I assume you drained and cleaned the gas tank already. If still no joy, remove the carb and clean it using spray carb cleaner. Remove the air screw and throttle screw and spray into the screw holes as well as all the little drill holes in the carb body. The object here is to clean out the pilot jet and idle circuit. When re-assembling the carb, put the air and throttle screws back in and turn them inward until they LIGHTLY seat. Now open each of them up one and one half turns. This is the factory setting. Please rate my answer.

I have a crf 450 with no spark new stator and coil plus have tryed a second hand cdi unit


Hi, Gladys_rober 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 CKP, CMP, or BAS sensor.
8. Faulty ignition switch.
9. Tilt sensor needs a reset.
10. Security alarm failing to disarm needs reset

My 04 crf 450 is leaking oil out of the air box breather


Hi, Jmattison21 and the usual suspects are:
1. Oil tank/system overfilled.
2. Faulty breather valve.
3. Engine breather hose bent, pinched, kinked etc.
4. Air filter has too much "pre-oil".
5. Crankshaft seal failure allowing transmission fluid to migrate.
6. Blow by drain tube cracked/split or filled to capacity.

Crf 450 carnt get a spark


The people who rebuilt it should have made sure it ran before giving it back. Check that there are no loose wires, and especially check that the plug which plugs into the black cdi unit is in correctly. Also make sure the coil is wired correctly.
