Why is my motorcycle buzzing when I try to start it?
The buzz is caused by the starter relay cycling rapidly. The battery has enough juice to pull in the relay contacts with a click which routes current to the starter motor. But that load causes the weak battery voltage to drop below what it takes to hold down the relay contacts so they open with a click.
What does it mean when a motorcycle cranks but wont start?
This is important – if the starter motor sounds like it’s turning over, as usual, your issue is probably the battery. If the engine cranks but doesn’t start, it could be having trouble producing a spark, getting fuel, or creating compression.

A buzzing noise that occurs when you turn the key is often the result of low electrical current flowing to the starter motor. This means that electrical power is getting to the starter but not enough to make it actuate and engage with the flywheel.
Why is my motorcycle not turning over?
Almost-dead battery – If the starter motor is only turning slowly this is usually a battery problem, too. We can jump-start the engine with jump leads, bump start it (depending on the bike), or charge the battery if there’s time. If the battery is dead, it might not take a charge and will need replacing.
Can you jump a motorcycle with a car?
It is possible to jump start a motorcycle with a car. This method should be used as a last resort as there are a lot of risks to the motorcycle. When a car is running, the voltage can run high enough to damage the electronics that are on a motorcycle, but if you’re careful, jumping it with a car is a valid option.

What does a dead starter motor sound like?
A bad starter’s tell-tale noise is loud clicking. It can either have a fast tempo, click-click-click-click-click-click-click-click or a slower lilt of click, click, click, click.

What’s wrong with my carburetor?
John Glimmerveen is a former competitive motorcycle racer. He later worked as a race technician for several international race teams. Carburetor problems generally fall into three areas: too lean a mixture, too rich a mixture, or an incorrect adjustment. Luckily there are telltale symptoms that will tell you which problem you’re dealing with.
Why won’t my motorcycle start?
If you have a motorcycle that won’t start, the carburetor may be dirty and will need a good cleaning. This means that the jets inside are probably clogged with deposits which means no fuel can pass through at all.
Do motorcycle carburetors wear out?
However, as with all mechanical devices, carburetors require periodic tuning and service, and will eventually wear out. Before attempting to fix a carburetor problem on your motorcycle, you need to come up with the correct diagnosis. When a carburetor is running lean, the fuel-to-air ratio is off because the carburetor is delivering too much air.
