Things You Should Check In Motorcycle During Cold Start Problems

The helmet is done. Check the jacket glove inspection Snacks and emergency supplies in the backpack are done.

You put your leg over the bike and press your thumb against the starter.

But nothing occurs!

We'll explore the typical causes of cold start issues in this post, along with some practical advice on how to avoid them by a Vintage Harley Davidson motorcycle parts manufacturer -

Shall I start the motorcycle in the morning?

As long as you take the proper precautions before starting your motorcycle in the cold, it is okay to do so.

Some bike riders in cold climates switch to a low viscosity oil that warms up more readily in frigid conditions in order to get their bike ready for winter riding.

The most crucial thing to remember when starting a bike cold is to let it warm up to operating temperature first.

After starting their bike, many inexperienced motorcyclists make the frequent mistake of aggressively revving the engine. If you do this too frequently, your engine may suffer harm.

Is it Common that Motorcycles Won’t Cold Start?

For new riders who may not be familiar with how to maintain their bike while they aren't riding it, this can be a typical issue.

Motorcycles with carburettors experience cold start issues more frequently than contemporary fuel-injected ones. However, EFI vehicles are still susceptible to cold start issues, especially if they are poorly maintained.

Battery discharge, poor fuel quality, or fouled-out spark plugs are the most typical causes of cold start issues.


Models with carburettors are more prone to experiencing issues with cold starts. This is because carburettors struggle to enrich fuel when the engine is starting. Since EFI systems are automated, the air-fuel ratio can be changed.

Make sure you are using the choke if your carburetted bike is difficult to start in the morning.

The choke valve reduces airflow to the carburettor(s) and permits a higher fuel-to-air proportion, which makes it simpler to start the motorcycle.

Your bike may also be more difficult to start if the gas in the float bowl of the carburettor is stale.

Spark Plugs

Your engine starts when a spark from a spark plug ignites it. You can have trouble starting the bike from a cold start if they are fouled out.

For details on how to remove your spark plugs, consult your owner's manual.

A spark plug might foul out for a variety of reasons. If your bike is running wealthy is one of them. This indicates that the bike is receiving excessive fuel.

On motorcycles with carburettors, the issue may be fixed by a straightforward adjustment of the fuel mix screw. On fuel-injected motorcycles, it's possible that one injector isn't closing all the way, allowing more gasoline to enter.

Not all of the carbon in the fuel can burn if the bike is running rich, and the deposits attach to hot areas like the spark plug tip. Your spark plug tips will get black or grey as a result of this.


Fuel has a limited shelf life, particularly now that more ethanol is used to make gasoline.

Long-term storage of fuel on your motorcycle will likely result in harm from the fuel breaking down in the tank.

Ethanol attracts moisture as it degrades. Your tank's rust may begin to accumulate due to dampness, and gaskets and gasoline lines may corrode.

Perfectly said by a Vintage Horex motorcycle parts manufacturer, if it has been sitting for a while, it loses its ability to burn, which makes starting it very impossible.


Usually, this is the cause of bikes not starting. Batteries can be picky and degrade if they are not properly maintained.

If your battery has been sitting about for a while or is electrolyte low, it may eventually die. A battery will discharge in colder conditions than in hot ones.

If your bike makes the terrifying double click sound when you press the start button, get a new battery from your neighbourhood motorcycle parts store.
