If you have air fuel and spark, you have everything it takes UNLESS! That wire did a no no like shorting out. Where did the wire go? and what color was it?.

1997 rm 125 won't start why should I do?


For your dirt bike to run you need 3 things:

1. Fuel (gas/air)
2. Compression
3. Spark

Start trouble shooting through these. Make sure your gas is turned on, and that it flows through the carb; if you tilt the bike does fuel run through the overflow tube in the carb? Make sure you have good spark; take out the spark plug from the cylinder, still connected to the ignition wire touch the threaded end to somewhere metal on the engine and turn the bike over. You should see a spark. Finally, do you have good compression, how hard is it to kick over etc.

These are the first things to trouble shoot, I would look on youtube if you don't know what you're doing, there are plenty of helpful videos there. You can also try putting a thimble full of fuel into the cylinder and then kick it over to help it start if it has been sitting a while.

2000 suzuki rm 80 new piston rings top end kit bike wont run rite starts sometimes but only runs for a minuite or so then bogs out and wont start again .


What this sounds like is a carb issue. There are screws that are located on the carb that control the air and fuel mixture, if you are getting to much air then it will crank and run only for a minute or two then shut off. Have you tried adjusting it? It can take some time to get it right as each bike engine is going to be slightly different and all adjustments are going to be bike/engine specific. I would recommend adjusting the air and fuel mixture, that will probably work for ya. Hope that this helped.

Rode my 2004 rm 250 for 2hrs, as soon as i got to truck it died


Hi, Anonymous and the usual suspects are:
1. Severely discharged or a damaged battery must 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. Faulty alternator/generator and or voltage regulator.
3. Loose or corroded battery terminals and or cables especially the "NEGATIVE" cable, look for loose, corroded, or broken connectors inside the cable harness at "BOTH" ends.
4. Faulty main circuit breaker or ignition switch, check for loose connections and continuity.
5. Faulty system and or ignition relay, check for continuity.
6. Faulty ignition coil, ignition/electronic module.
7. Faulty CKP, CPS, CMP, MAP, TPS, or BAS sensor, corroded, loose or broken wire connector pins/sockets.
8. Throttle cables and or idle speed improperly adjusted hot idle speed should be 950 RPM to 1000 RPM.
9. Faulty neutral, side stand or clutch lever safety switch.
10. Fuel tank empty
11. Fuel tank contaminated with ethanol sludge.
12. Water or dirt in the fuel system, or clogged filter.
13. Restricted, blocked or kinked fuel line.
14. Faulty fuel pump.
15. Faulty pressure regulator.
16. Faulty or clogged fuel injectors.
17. Lean angle switch is faulty or needs adjustment.

You need to check the fuel filter -- follow the fuel line from the tank down to the filter, should be tucked in below the seat..

I replaced the cylinder and piston and rings on my 98 yz 125


You may have not tightened coil and coil wire screws enough. 2 strokers are notorious for vibrating their bolts loose. Bad earth will nullify spark. Check for clean connections on all leads from crank to coil and CDI unit. Is plug and cap 100%. Check top end gaskets if any sign of moisture on sparkplug.

The float pin may be worn and extending out past ends and jamming on carby housing. Take out and roll on flat surface and look for defects. Ensure float tab (bears on needle) is not notched from wear or bent too far. Clean seat and needle are essential, replace if suspect. Spray some carby cleaner thru fuel line entry whilst you have floatbowl off to clear any sediment or debris. (especially fuel scale or air filter foam)
Cheers.

125 wont idle


One of two things come to mind:

Either your pilot circuit is too lean (colder winter air needs more fuel) or your compression is down. 10 hours on a 125 top end doesn't sound like much but the longevity of the top end depends on many variables including how hard it is ridden, mix ratio, jetting, compression, etc. To me, 10 hours is a lot for a 125.

Where are you located and what is the temperature there? If it ran well in 75F weather and it's now winter, it's likely in need of a larger pilot jet.

It wontt start it has spark


There are only three things that your bike needs to start, Spark, Compression and Fuel, if you say that it has spark and compression then the problem has to be fuel, Make sure that there are no blockages in the line from the tank to the carb, if that is not the problem then you will have to pull the carb and clean out all the ports. I disassemble them as much as possible and empty a can of carb cleaner into a clean coffee can let it soak overnight and then blow out all passages with compressed air and reassemble. You should also pull off your reed cage and check to make sure that your reeds aren't cracked or broke. If your bike was runninng before and you give your carb a good cleaning and the reeds look good and it still doesn't work then you are going to have to look at the other two requirements, your spark should be a bright blue, if not try a spark plug first (you may want to try that before the carb cleaning) next you should get a compression tester and check the compression to make sure it is high enough. Your bike might feel like it has lots of compression but it might be low enough to make it hard to start.
