What did the spark plug look like when you first took it out? Was it black/wet/sooty or was it a light tan/gray color. If it was black/sooty, then I would guess you need a coil. I know you said it had a good blue spark when you checked it, but if you poured a little bit of gas in the cylinder and it still wouldn't fire that would be my first place to check. If it ran briefly after you poured a bit of gas in the cylinder and then died, then it's a fuel supply issue. Remove the line that goes from the gas tank to the carb and make sure you have gas at the carb. If you have gas, then I would remove the carburator and take it apart making sure all the jets and passageways are clear. Use carb cleaner and an air attachment and if you still can't get it out, use a small wire to clear things up.

Reassemble and it should run, otherwise report back and we can go to the next step.

IF you have a battery get a new one ; put in new gas ; super; dsid you ajest any screws on carb. You tight need to run a prime tank right to your carb to prime it; and then hook your tank backup new gas lines to your carb. Now break out with the WD40 to spray all switches for rust.

SOURCE: honda cbr 600 wont start

hi, each lead has the specific number on it. if you do this correctly then they genrally give you an idea to where the sit in the coils( the way they bend :-) ) also i believe the coils are better off been attached to the frame once you are sure leads are in corect order and possitioned correctly in the coils.i just presumed the coils neaded earthing. make sure battery is pleny charged as a bad battery can just hinder. it is also very easy to flood the bike so just check the plugs again. if they are unusually wet then dry them off and try again . otherwise maybe try cleaning all electics.

hope this somehow helped

SOURCE: 92 honda cb 750, oil light will not go out, bike won't start

Look around the engine oil drain plug and fill area and see if there is an electric sending unit( small plug with a prong for a wire) that is screwed into the engine if so check to see if its unplugged / could be a low oil cut off switch that kills all power to the ignition if the oil is to low ( or the wire is unplugged)

SOURCE: 2000 honda 1100 shadow spirit. Rough idle, little power.

Replace the spark plug caps and try again. On Honda's the cap is often part of the wire (a dealer part) NGK makes some inexpensive plug caps about $5 each. They should OHM out to 5000 anything above or below and you need to replace them. This should fix the problem.

Honda 1996 cr 250 wont start


Hi, Walter and the usual suspects are:
1. Fouled spark plugs.
2. Discharged battery, needs to be 12.5 volts or better and be able to pass a "LOAD" test, your battery may show 12.5 volts but has little or zero amps and must be replaced.
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 CDI 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

2005 HONDA CRF 250 R HARD TO START WHEN HOT


Hi, Stevensmi601 your bike starts great when cold but once it reaches operating temperature and the engine is shut off for a few minutes then you try to restart it and it will turn over but will not fire or it doesn't do anything, the usual suspects are:
1. When electronics get hot they build up resistance then stop working. It might be an ignition coil, stator, CDI unit etc. First, you must find out if the spark dies out. When the bike won't start, pull a plug wire off, stick a new spark plug in the end and ground the threads on bare metal while someone cranks the engine over. You should see a nice big blue spark between the spark plug gap. Incorrect spark plug gap will cause or contribute to a no start when hot issue.
2. Fuel Tuners have been known to cause this type of problem, disconnect it and see if resolves the issue.
3. Any engine management sensor could be faulty especially the ones that monitor temperature.
4. Gas cap not venting properly, improperly routed fuel lines they must always go down from the gas tank to the carburetor never in any kind of a loop this will cause a vapor lock. Clogged, bent, kinked, pinched or restricted carburetor vent lines will do the same.
5. Overhead camshaft valves adjusted too tight when cold, this will cause loss of compression when hot, except for pushrod engines they usually get looser when hot.

try a new spark plug. if u fowl out a plug some time they will not fire under compression.2 strokes need. fuel,fire and air, very simple engines.it is possible crank seal are bad .that doesn't allow the engine to create vacuum in the crank case.thus fuel and air will not make it to combustion chamber.

My quad bike sparks at plug petrol getting to the plug but cant get it to fire up v_a_ward@hotmail.co.uk


Check your air filter. Make sure the air box is very clean and you could try removing the filter completely. Don't ride it like that, of course. Also, make sure the spark is white/blue not orange. And that the plug isn't too wet as that could mean a flooding condition.

Basicaly brand new cr25o mx bike wont start


Assuming you are using fresh gas. Check to see if gas is coming out of the line, if not blow back up into the tank and if that works there's dirt in the tank. Check the spark by removing the plug and kicking it over with the plug touching the engine, look for spark. If no spark, try a new plug, if still no spark, you have a stator problem. It wouldn't hurt to clean the air filter in any case. Good luck!

I just got a dirt bike and i don't know the gas oil mixture for it?


If your not sure you could start with a 50 to 1 ratio if you notice a lot of smoke thin it out a little but the biggest part of adding oil to the gas is to keep the cylinders lubed. another thing lyou can do is check your spark plugs after a while to see what kind of burn you have.

I have a pit bike 125 its not starting wot so ever got good spark but still not start


If you have spark them it must be gas. eather no gas or to much gas. Put it on chock, be sure the shut off valve is in on position.Now crank it over a few times , if it wont fire. Check the plug , is it wet or dry .If its wet then it may be flooded and needs to dry out and air out the cylinder.Try starting when dry. If its dry try putting a 1/2 oz of gas into the spark plug hole. replace the plug and turn it over . This will get them to fire up. Good luck DFD
