When your KLX coughs and attempts to die (losing power), it is normally the spark plug wire(s) that are bad. Any electrical component can also do this when getting wet but most of the time it is the coil arcing when damp or the spark plug wires. The next time it does the coughing thing, stop and spray the wires and any other wet electrical component with WD_40. If it begins to run correctly after the spraying with WD-40, the moisture has been displaced by the wd-40 and the wire(s) or some electrical component gets damp and can not operate. Replace the spark wire(s) or repair the other components.

Sounds like coil or plug wire is getting wet. Could also be ignition system also. Check everything and try spraying the wires with silicone spray to water proof it.

I think you would be better of checking the ignition pick-up located on the right side engine cover. you may want consider searching for info on the ignition pickup, as apparently it is a weak link on these engines. That was the first thing i repalced when i got got mine as it had sat for a while.

SOURCE: dies at idle

  1. Carb jets may still be dirty or improperly sized.
  2. The Cam and/or Cam journals are worn down and allowing some play in the timing.(Very common on the XR's)
Sounds more like carb or timing issues to me

The stator could be going,but it doesn't sound like this is your issue.

SOURCE: cutting out

I'm not too familiar with Triumphs but assuming your bike has carbs and not fuel injection, then it is time to clean the fuel system. Remove the water trap bowl at the bottom of the petcock, (gas valve). Is there any water or trash in the bowl? Drain a cup of gas from the tank. Is there any water or trash in the cup? Dump it, clean it and re-mount it, ( not all bikes have a water trap bowl ). Install an in-line fuel filter.

For each carb > Drain the carburetor. There should be a screw on the lower side of the carb float bowl. Remove the screw then replace it after the fuel drains. Turn the gas back on and wait a minute for the carb to fill with gas. Install a new stock NGK spark plugs and start the engine. If the bike doesn't start and run properly then shut off the gas and remove the carburetor from the engine.

Remove the float bowl and clean the entire carb with a spray carb cleaner from the auto parts store. Wear protective goggles to avoid getting spray in your eyes. Spray into all the little airways and fittings in the carb. Remove the idle screw and the air screw on the outside throat of the
carb and spray into the screw holes as well.
< < READ CLOSELY > >
Be sure to put these two screws back in the same hole they came out of. IMPORTANT > do not tighten these two screws down. Only screw these in until they LIGHTLY seat. Now turn each screw one and one half turns outward. Put the rest of the
carb back together, clean the air filter and install the carb. Let the float bowl fill then start the engine. This process should get you back on the road.

You may want to go to a richer main jet. If the jet is (for example) a 178 then change to a 180 or 182. This should fix the top end problem. Do this only if cleaning the carbs doesn't work.

Please rate this solution. Thanks!

SOURCE: my honda cbr 600 is struggling as if it keeps

It all seems to be leading to fuel starvation. Have you checked the tank breather is not blocked which can be a small hole in the petrol cap or a tube from under the tank. It could also be a blocked fuel filter. There should be two. One inside the fuel tank under the petcock, another before the fuel pump. Here is the workshop manual where you can find all info you will ever need for this bike.

Coughing and splattering


have you had the dispack changed on any of this trips to the mechanic's as it sound to me to be this. it would take around 30 min for it to over heat if it had a fault. then you would get a low spark, no power and eventually just stop working all together.

, black carbon deposit on spark plugs starts spitting and coughing


You didn't say what year or model bike you have or whether it's fuel injected or carburetor equipped. If it's equipped with a carburetor this condition is usually caused by warming the engine too long with the enricher on. The enricher provides a very rich mixture to start the engine with. I've seen people start their bikes and let them run for ten minutes with the enricher on. They foul a lot of plugs to. Use the enricher to start the bike but as quickly as you can get the bike to run without it, turn it off and use the throttle grip to keep the engine running until it will idle by itself. I use the throttle lock underneath the throttle housing.

You may have an air leak (extra air getting in) between the carbs & the engine. Inlet manifold rubbers do crack on Hondas but Yamahas are the worst.
Check for cracks, check the o rings (each end of inlet manifold) & check for leaks from air-box to carbs
Carbs need to be balanced (synchronised) to let the engine run smoothly but will not produce those symptoms if left unbalanced.
You should also check the HT leads & spark plug caps for shorting, run the bike in the dark & look for sparks going to earth (sometimes you can only hear a ticking as the spark jumps across). Make sure the leads are not touching anything during this procedure

Bike sparking and compression ok cannot start bike when cold this year any solutions thanks bike is year 1981


Either the spark is at the wrong timing when you would hear backfiring or coughing at least,if not it is fuel related
Check the reed valves are closing proerly, that the carb & jets are clean, & they have FRESH petrol
It sounds like it may not have run in 6 months or so in which time petrol goes off ( water can get in to petrol quicker giving the same effect

Hope this helps (if so please mark as helpful !!)

Headlights brighten and dim when accelerating, 2003 Road King


Your heading for Stator problems 'ol son,...........
Before long, the engine is going to start coughing & spluttering, eventually it will stop. Let it sit awhile, if the battery in good shape, it might start again, but it won't last long before it stops again. Last time it happened to me, I was on an 800klm long highway, just on dusk, turned on the lights, (custom bike, actually has a headlight switch) got about 2ks & it died. Ever spent the night, freezing cold on a highway no one uses?
Get your charging system checked A.S.A.P!

The battery on my 1995 Yamaha Virago 250cc is not working


starter brushes could be worn out or a dirty or loose connection!
Starter button may need checking also the solenoid
week compressin or leaking diaphrams in carbs will cause it too
I suggest you charge battery & start at the button & work your way back
