Motorcycle Won't Start In Cold Weather

Winter is here and it's time to gear up for the cold weather. But what do you do when your motorcycle won't start in the cold? There are several reasons why your motorcycle may not start in cold weather. In this article, we will explore the causes and solutions to help you get your motorcycle up and running in no time.

Dead Battery

A dead battery is the most common reason why your motorcycle won't start in cold weather. Cold temperatures can reduce the battery's capacity, making it difficult to start the engine. If you hear a clicking sound when you turn the ignition, it's a sign that the battery is dead or weak.

To avoid this problem, make sure to keep your battery fully charged during the winter months. Consider investing in a battery tender or trickle charger to keep your battery charged when not in use. If your battery is dead or weak, replace it with a new one.

Fuel System Issues

The fuel system is another common culprit when it comes to starting issues in cold weather. Cold temperatures can cause fuel to thicken, making it difficult to flow through the fuel lines and into the engine. This can result in a rough idle, stalling, or a complete failure to start.

To avoid fuel-related issues, make sure to use a fuel stabilizer during the winter months. This will prevent the fuel from thickening and clogging the fuel lines. If you suspect that your fuel system is clogged, you may need to clean or replace the fuel filter.

Spark Plug Problems

A faulty spark plug can also prevent your motorcycle from starting in cold weather. Cold temperatures can cause the spark plug to become dirty or fouled, making it difficult to ignite the fuel mixture in the engine. If you notice a weak spark or no spark at all, it's a sign that your spark plug may be faulty.

To avoid spark plug problems, make sure to replace your spark plugs regularly. Check the manufacturer's recommendations for the recommended replacement interval. If your spark plug is dirty or fouled, clean or replace it with a new one.

Low Engine Compression

Low engine compression can also prevent your motorcycle from starting in cold weather. Cold temperatures can cause the metal in the engine to contract, reducing the compression ratio. This can result in a weak or non-existent spark, making it difficult to start the engine.

To avoid low engine compression, make sure to warm up your motorcycle before starting it. This will allow the metal in the engine to expand and increase the compression ratio. If you suspect that your engine has low compression, you may need to have it serviced by a professional mechanic.
