How to assess Bike Engine Health

Bike engine health is important for every rider in fact who doesn’t want to keep their bikes new and healthy? There is a general tendency not to repair or care for your bikes a few months / years after purchase. To keep your bike in good condition, there are a few simple things that you should do on a regular basis. Here are some of the ways you can keep your bike engine health in check

Both the sound and the feeling are important.

The first click or squeak of a loose valve or poor bearing will definitely grab your attention if it develops reasonably fast, so you don’t have a chance to grow used to it. However, if you are intimately familiar with every sound and movement of your motorbike, you will probably be surprised. In the same way, you’ll pay attention if the vibration’s frequency or intensity changes. Wheels, chains, and other rotating components can, of course, generate vibration. If you swap gears or turn off the engine and let the vehicles coast, you’ll generally be able to identify which one it is. At the very least, it’s in the front of the drivetrain if the frequency varies with the engine.

Consumption of oil

Without gauges, this might be a warning sign of a problem with the internal combustion engine.

With proper break-in (i.e., you didn’t pamper the engine but ran it hard for the first few hundred miles), it should consume oil at a steady (and low) rate over the next 1000 miles or so. It’s easy to notice variations in oil consumption if you make it a practice of properly filling the crankcase to the same level each time you add oil (which may only be during oil changes on liquid-cooled motorcycles), then checking the level on a regular basis, say once every 1000 miles or so.

If you find yourself adding oil more frequently, there may be an issue with the engine’s top end, such as a ring or valve seal failure. Changing your oil or riding style might affect how much oil you use. If you use a thinner oil or ride quickly in hot conditions for lengthy durations, your bike may require more oil. If the oil begins to degrade after prolonged usage, you may observe an increase in oil consumption. After some practice, you’ll be able to recognize these typical fluctuations, but an increase in oil consumption that doesn’t make sense should be investigated with a compression test.

Consumption of fuels

Another potential warning indicator is an increase in gasoline usage over time, although this does not always imply you have an engine issue. It may be a squeaking brake, a squeaking chain, misaligned wheels, low tyre pressure, a change in driving habits, a filthy air filter, the influence of new accessories, a changed fuel composition, or simply time for a tune up.

Compression Checks

Compression tests come in two flavours: a basic measurement of compression and a leak-down test, which examines the cylinder’s capacity to maintain compression. Both can provide valuable insight into engine-related difficulties.

The most simple compression tester is well-known by mechanics at home. This low-cost pressure gauge monitors the heated engine’s maximum compression pressure when the starter turns it over. You make a comparison between the measured value and the value specified in your shop manual. If it’s too low, you’ve got a problem, but you won’t know where until you run further tests. In the event that adding a drop of oil to the cylinder fixes the issue, then the rings are to blame. (An accurate gauge measurement of overly high compression generally indicates a substantial deposit build-up in the combustion chamber).The pressure in a hot engine is likewise measured using a leak-down test, but this time you use a compressor to compress your own air instead of the engine’s. With the testing equipment, you can find out how well the cylinder holds compression at a preset pressure, generally about 80 psi. Most significantly, it makes it simple to locate the source of the compression leak. If the pressure lowers at a specific point in the piston’s stroke, you can move the piston up and down in the cylinder to identify a fault. A worn or jammed ring or a bad valve seal is more likely to be the culprit, and you can tell which one it is by listening and adding oil. Pressurized air can be detected by listening for leaks.

 An issue with your exhaust valve seating can be heard through the exhaust if it is loud enough to be audible. If air is escaping from the carburetor, the problem is most likely with the intake valve (s). Oil filler or crankcase breather hissing indicates blocked or worn rings are causing the problem.


Engine gauges are an option on a small number of cruisers. When it comes to cruiser instrument panels, the most frequent engine function monitored is the temperature of the coolant. If you want to customize your dash, you may install additional gauges to monitor the engine room. Among these are the temperature and pressure of the oil, as well as that of the cylinder head. Most bikes come with pre-wired temperature gauges. Finding a source of oil pressure may be a little more difficult, however virtually all bikes include an idiot light to check this function.

Regardless of whether your gauge is an optional extra or standard equipment, you should become familiar with its routines. Plastic tape works well for marking the gauge’s usual operating range. Increased load or rising ambient temperature can induce a rise in temperature, but if those circumstances aren’t present, it should be looked into. It can indicate a wide range of difficulties, including carburetion issues, ignition issues, various engine ailments, non-engine issues like increased drag, or just a faulty gauge or sender. A reduction in oil pressure may be due to a faulty gauge or debris in the sender, but it should always be investigated.


Maintaining bike engine health is very crucial because it extends the life of your motorcycle and a healthy engine means you don’t have to make frequent visits to the mechanic. There are certain things such as bike engine oil that you can get from car accessories and parts stores  and keeping such things handy will save you money on major repairs.
