Question about 2002 Honda CR 125 R

1 Answer

My 2002 Cr 80 big wheel is continually flooded. Spark plug appears to be too wet. Is it a carb problem or more complicated? I've turned off the gas and choke and tried to dry the head out by bumping it down a driveway. It almost started, then bogged down. It still wouldn't fire. What should I do next? Is it possible the gas is too rich? I borrowed gas from a neighbor. Thanks

It is eather the spark or your floats clean the plugs and ground them to the heads and kick it over if you get a good spark then its your floats.

My cr 80 won't start but it's popping like it won't s to replaced spark plug an couple over things please help me sum one


Hi Lennard:
Cars and trucks section but CR80 sounds like a motorcycle. right?
You need two basic things:
1) Spark - pull the spark plug, connect the lead, hold against the head, and spin it over. Spark shoulld be hot and blue.
2) Fuel - Drain tank and fill with fresh gas
Drain and flush carb
If it has a filter, make sure that fuel is flowing through it.
Try a "normal" start........... choke, kick over 5 times. If no start, remove plug and check for fuel in cylinder. Wet plug means no spark. Dry plug means no fuel.
If dry plug try priming the carb (give it a squirt of gas with choke off)
It should try to start.
To let me know how you're doing, reply as a comment on this post.
Cheers.

2002 honda vt 750 shadow spirit one cylinder won't fire what's the problems


Pull the plug out and test it on the frame. If no spark you need new plugs. If it does spark look at the plug. If the plug is black and wet it is getting to much fuel and flooding. You will need to adjust your carb's air to gas mixture.

My toro mower will not start now after it has sat all winter


Make sure you have spark..pull plugs and roll over and look for blue spark, next smell for gas or see if plugs are wet....if they are wet its flooded with old gas which is not very combustable, remove air cleaner and put spark plugs in and spray some carb cleaner in the throat of carb and see if it fires, now if that works then you may have to check the needle and seat and the solenoid on bottum of carb if either one of these are stuck you will not get gas to the carb to run, hope this does it for you! don't forget to reply !

My 2002 Honda Cr 125 will not start. After about 20 kicks it makes this popping noise from the exahaust. It has good gas and the carb has been cleaned.


pull the spark plug check if it is wet/fouled,clean and dry it,then ground the pug to the head spin the motor and che the spark to see if you have spar arching across to the electrode tip if it is not and you hear but do not see it and it is sparking within the body of the plug replace it.

Flooded? Try a new plug, or get that one cleaned up. If it is sparking and wet, it should fire, even if it doesn't run, it should spark. Did you put the jets or the needle valves back to where they were? I think they start out at 1 1/4 turns out , then adjust the low and high. If it is fouling out with too much gas, the low speed jet is open too far.

Bogs down and smokes through the first three gears. theres no snap.


sounds like the bike may be flooding. Assuming the oil mix ratio is correct, pull and clean the carb, pay attention to the float make sure it does not have a hole in it or is not logged with fuel. Have you done any carb work on it if you have changed the jet in the carb it sounds like it is too big, try going down a size or two.

Put new carb on 86 cr 80 ran fine 4 10 minutes then quit changed spark plug and gas still nothing. has spark dont know how hot also changed manifold appeared to be dry rotting still nothing. even attemped...


for any motorcycle to run you need three things. spark, fuel and compression. i see you've tried to get fuel and spark. if you have spark thats one down. dont pour fuel into cylinder. instead spray tiny bit of brakeclean or carb clean into spark plug hole. i have a feeling if you drained your gas after the carb clean the carb most likely sucked bad gas back up and might need cleaned again. ive seen it happen alot on ols bikes.

98 cr 125 has spark and gas but wont start. seems to be flooding the engine. gas is building up in the pipe. the carb doesn't seem to be controlling the flow of gas right


you should open the carb and check the floaters and the pin they control.Then adjust the float height and test it before you put it on the bike.Empty the gas from the engine 'cause it will damage the crankshaft's oil seals.

Your bike needs 4 things to run-Fuel, Spark, Air and Compression. One or some of these are missing.

1) Crank engine over several times to start. Remove spark plug. If plug is wet and smells like gas then it is getting fuel.

2) Check for spark
Put spark plug back into spark plug cap and lay spark end along side bolt or part of unpainted head making contact and crank over engine as if to start. If no spark then is electrical problem. Try changing spark plug. Check grounds. If not plug or grounds then purchase a shop manual from your local dealer and ohms test all electeical componet resistances as shop manual instructs. Be sure components do not meet specks before purchasing.

3) If has spark and plug was wet upon removal then gas has water or just old gas. If you drained the carb via bottom of carb screw into a clean clear container and see stuff at the bottom then carb is dirty with water and or dirt.

If your bike has been sitting along time condensation will build explaining water and or gas will loose its kick after sitting too long. If you think it has been sitting a long time it is best to dispose of old gas and refill with new. Water can also get into tank from gas can when fully tipped upright so dont dump every last drop into the tank...most ofter the last couple of cups are water.

If bike has been sitting for a few days and was running fine before that, turn off gas, drain carb via bottom of carb screw, close off screw and turn gas back on. This will refresh the gas in carb.

If none of these are the case and you have good fuel, good spark...check air filter for air flow. If all this is good then you need to do a compression check. A simple way to do it is to stick your finger in the spark plug hole and hold it in there with some force and have a friend try to start the bike. If it blows your finger out then it has compression. If it doesnt want to force your finger out then you have no compression and is a piston and ring problem. The only way to test compression for sure it to purchase a compression tester from auto parts store that has an adapter for your size plug hole and do a proper test. I hope this helps.
