Is your bike not starting after you left it in the rain? Here’s what to do

Modern motorcycles have way more electrical components than what previous generation models came with. And while that has enhanced the riding experience, you need to be extra careful when the monsoons arrive. Onboard electronics and heavy rain are not the best of friends, and despite rigorous testing and protective measures, they are prone to wear and tear, and can get exposed to the natural elements. Which is why, when it rains, it’s ideal to find an enclosed space for your motorcycle. But that may not be possible all the time, and sometimes, your bike might not start after a heavy spell of rain. So, read on to know the reasons and how you can address such issues. Also keep a comprehensive bike insurance policy handy, since it will protect you financially in case your vehicle gets damaged in a natural calamity, which is not impossible when monsoons wreak havoc.

Reasons behind your bike not starting

1. Watered down fuel

   Water can seep into the fuel tank, adulterating the fuel chemistry. This adulterated fuel is difficult to ignite for the carburettor. It is more prominent in motorbikes with pod filters instead of an air box. So, clean out the bowl at the bottom of the carburettor and your air filter too.

2. Ignition malfunction

Water in the ignition system can cause ignition failure. If water is in the coils, it can cause corrosion. The corrosion can in turn cause the coil windings to short, requiring a replacement. The ignition switch comes with other electrical contacts as well that signal off, run and start positions. With water in the system, the electrical connection will remain incomplete, causing a no-spark condition.

So, can you keep your bike in the rain for long?

Motorcycles are designed to be an all-weather transportation system. If motorcycles were easily spoiled by the weather, they wouldn’t account for nearly 81% of the existing domestic automobile market. This means, you can allow some rain to fall on your bike, but prolonged exposure to rainfall and adverse weather conditions can cause damage like rusting.

• External effects

  Oxidation is perhaps the biggest threat to a bike. Metals used in their production are prone to rust. While they are given a protective coating, maybe chrome, paint, lubrication, etc., the treatment is prone to scratches and chipping. The metal is then exposed to water and oxygen. The rusting process begins from this tiny exposed section and can continue underneath the paint or chrome – a phenomenon called rust cancer, or blistering. These damages, if unchecked, can rack up serious bills.

  Generally, the parts closer to the ground are more susceptible to rusting. Springs, wheel rims, exhaust tips, chain and shocks are usually the first to start rusting. Even if taken care of, there is a high chance of rust development given that there is constant exposure to mud and water.

• Internal effects

If water gets into the engine, it can cause loss in lubrication and rusting of internal components. The various components that require electricity to function can get disrupted by the extra resistance that corroded parts offer. These electrical circuits are difficult and expensive to repair.

Here’s what you can do to prevent a no-start situation

1. Keep the bike in a shed

   This will protect it against natural elements. The bike won’t get rained on, and direct moisture will not be a problem. This will help keep the bike dry, and with a slightly warmer ambient temperature in the garage, it will start fine.

2. Park in a carport

   If you cannot keep your bike in a garage, a carport is the next best option. It will protect your bike from rain, but you may still need to ensure that the flooring is sloped, so there’s no accumulation of water.

3. Use a bike cover

   If a garage or carport isn’t available, and you need to park your bike in the open, consider purchasing a good quality cover. A decent cover won’t wear or tear easily and keep the bike functional. The bike cover will also protect the paint against the effects of the weather.

4. Wipe dry and displace water

   If your bike does get wet, wipe it dry with towels or an air dryer. The chain and other metal components are prone to rust even with atmospheric moisture. Use an industrial solvent such as WD-40 to displace water from the metal components and keep them from oxidising. Keep a spray can handy and use it on potentially weak spots (in terms of rusting), to prevent further damage.

5. Get bike insurance

While normal wear and tear is not covered under an insurance policy for bike, it is still prudent to avail two-wheeler insurance online to protect yourself financially against accidents or natural calamities like floods, cyclones and so on. While third party bike insurance is legally mandatory, you should avail a comprehensive insurance policy for bike if you want all-round coverage. You can also choose add-ons to power up the cover and minimise hassles in case of an unforeseen event.

Conclusion

All in all, during heavy rains, it is best to keep your bike covered when not in use, or park it in a garage or carport. If your motorcycle does get wet, it’s advised to dry it off immediately, and to spray an industrial solvent such as WD-40 on the exposed metal parts from time to time. You can also air dry your bike or use a blower to remove water as soon as possible to keep it in great shape.
