Have your oil changed, replace the spark plugs, and clean the carburetor. When an ATV clicks when trying to shot, there are typically two possible culprits: the battery or the solenoid. Clicking when you try to start your engine usually points to one thing: the battery.
Follow these steps to help solve the problem:. If, however, the battery is not the reason, what might be causing the clicking? This sound could indicate a problem with the solenoid. A solenoid is essentially a relay between the battery and the starter motor. The starter motor is what allows the engine to start.
For the best results, take your ATV to a certified mechanic and allow them to troubleshoot and solve the issue for you. Sometimes you can push-start a vehicle. To do so, you have to get the vehicle rolling at a fairly decent speed mph , get on, and let out the clutch. If you hear the engine turn, you should be able to give it some gas and get it started. Then try starting the ATV as usual.
Spark plugs are considered consumables that may need replacing from time to time. A spark plug that has gone bad may prevent the ATV from starting and only cause it to backfire. A clogged air filter will restrict airflow and, therefore, significantly impact how rich your ATV engine operates. Too little air will cause an overly rich mixture, resulting in symptoms like the ones you experience. Another possible cause of these symptoms is that your valve clearance is incorrect.
As the engine gets some hours to it, the valves may seat deeper in valve seats and may need adjusting. Checking and adjusting the valve clearance on an ATV is not that hard to learn, but it is recommended that you ask for guidance from someone more experienced the first time you do this job. If you do it incorrectly, you risk causing permanent damage to your engine. If one cam is off by just one tooth, you may run into starting issues accompanied by the occasional backfire.
Lookup a timing diagram for your specific ATV and make sure all the timing marks line up. If the task of aligning the timing marks sounds intimidating, you are probably better off leaving the job to a mechanic. The timing might be off even if you did not work on any of the timing components. What often happens is that the timing advance key, also known as a rocket key, has sheared and needs replacing.
This little metal part is designed to break to protect other engine components. From time to time, it may break even if there is nothing else wrong. Luckily they are not that expensive or time-consuming to replace. It is not a job everyone will be comfortable doing for themselves. The key is located on the crankshaft. You need to unbolt and remove both the flywheel-cover and flywheel the flywheel on an ATV is actually called a generator to access it.
A flywheel puller may be required. If the key is sheared, remove all pieces from the old timing key and install a new one according to factory spec. Ask your dealer to make sure you get the right one. Install the flywheel and flywheel cover before trying to start the bike. Make sure the timing marks are lined up correctly.
The timing mark layout will be different from model to model. Please refer to your service manual. A dirty carburetor may prevent enough fuel from getting to the cylinder, causing a lean backfire. Due to the backfire, you know that at least some fuel is getting through.
Please refer to step 3 on how to clean the carb. Before spending money on a mechanic, it may be worth draining your gas tank and adding fresh gas. Gas may go bad if it sits too long, or it may get contaminated with water due to condensation. Your next best option is to pump or siphon the fuel out of the tank.
If a valve has stuck open, the compression will be too low, and the bike will not start. Repairing a stuck valve is usually a task for a trained mechanic. If all you hear when turning the key is a buzzing sound, it is usually because your battery is dead or needs charging.
Also, make sure all of the power wires going from the battery to the solenoid are correctly connected and not corroded. Put a test light across the connection you are testing as you activate the starter. If the problem is not battery-related, you may have a bad starter or even a seized engine, preventing the starter from engaging. All you can hear is a clicking sound each time you press the starter button.
The clicking sound is coming from the starter solenoid. A solenoid that is working correctly will provide an audible click as you activate the starter. But the solenoid may be bad even if it clicks due to internal corrosion. Use a multimeter to test if the solenoid closes the circuit as you try activating the starter. Put your multimeter to DC Voltage. The red lead goes to the starter side of the solenoid.
The black lead goes to ground. You often have a small black relay that is used to trigger specific components of the ATV to turn on. Make sure the connections to the key harness is tight and not loose. The key itself should fit in nice without much friction.
Make sure the key is not dirty and can make a good connection. I had one guy come in saying his ATV was hard to start and often would not start at all. He had power, and the kill switch was set to run, but it would not fire up.
I had him bring it in to see what the problem was and noticed that he was giving it gas when starting. This would be fine on a carbureted ATV, but on a fuel-injected one, this puts it in a state that tells the ATV computer to not turn the engine on.
If gas does flow freely, your problem is further down in the carb or injectors. If you have a fuel pump issue, it will most likely be the diaphragms inside the fuel pump or the filter is too clogged to allow fuel to flow freely to the engine. If you have a carburetor, the most common fix is replacing the needle valve and seat. Start by spraying some carb cleaner or ether into the carb or injectors and then try to start up the engine.
This could help you start to narrow down the issue. In that article I go through the most common reasons your engine may not be getting fuel and how to fix the problem. Make sure the air filter is cleaned out, and there are no obstructions blocking the air box intake. In that article I go through step by step on how to clean your air filter to make sure your engine is getting the right air flow it needs to stay running.
Aside from checking the air intake, also check the exhaust. Your ATV needs good airflow into the engine, as well as out.
