There is hardly anything more annoying: you march to your bike in full gear, full of anticipation for the ride, press the starter and then the bike just won’t start. Before you panic and call a tow service, or even take your bike to the workshop yourself, this should help you find the right solution.
Possible causes
The motorcycle battery is often the cause of starting problems, especially after long periods of standing still, such as winter storage. It is important to check whether other power consuming devices are working, such as the lights. If everything remains dark, the battery is empty. This can be helped by a jump start. Afterwards, the battery must be properly charged – so make sure you take it out for a longer ride. If the problem occurs again, the battery should be replaced. If your bike turns over but doesn’t start, and there is no issue with the battery, the problem could be connected to the ignition or fuel.
It won’t start — but the battery is good — other causes
An internal combustion motorbike engine works on a fairly simple principle. The correct fuel is mixed with air, compressed, and then ignited. The resulting exhaust gases must be expelled quickly and completely, otherwise the combustion cycle is obstructed. Therefore, these sources of error for starting problems can arise.
Firstly, with the fuel supply line: if the correct fuel is available in sufficient quantity, a vacuum in the tank can be the problem. To check, try starting the engine with the fuel filler cap open. If the engine starts, the fuel tank vent should be cleaned. It is also important to ensure that it is receiving sufficient oxygen: a clogged or dirty air filter does not allow enough oxygen to pass through to initiate proper combustion. When cleaning, it is best to check at the same time, that the air hose is correctly fitted and unobstructed.
Ignition coil failure — symptoms
There could be one or more symptoms causing ignition coil failure, among these are engine jerking, misfiring, vibrating, hard starts or sudden stalling. You may notice that your bike consumes more fuel than usual and your check engine light could have turned on.
It turns over — but won’t start
The most obvious step is to make sure that there is enough gas in the tank, especially after it has been stored for a while. Here are a few of the most common problems that keep your motorcycle from starting.
