As an enthusiast of RC model cars, I recently got my hands on the CISON FG-VT9 9cc V-Type Two-Cylinder Four-Stroke Air-Cooling Gasoline Engine. The moment I unboxed it, I was impressed by its sleek silver appearance and the meticulous attention to detail. This engine is designed with an overhead valve bottom camshaft top rod air distribution structure, which ensures smoother operation and better performance compared to other models.

The most striking feature for me was the anodized surface of the cylinder block and the chrome-plated rocker cover.

The CISON FG-VT9 boasts a powerful 0.8ps starting power, allowing it to run smoothly at a speed of 2000–8000rpm.

One of the standout aspects of this engine is its air-cooling system, which efficiently prevents overheating and prolongs the engine’s lifespan. Additionally, the electric drill start method and the sensitive single carburetor throttle response guarantee a seamless and enjoyable experience while operating the engine.

However, it’s essential to follow the manufacturer’s instructions to avoid potential damage. Suitable for individuals aged 14 years and above, this engine serves as a fantastic gift for any RC model enthusiast or model engine collector. The included air filter, spark plug, CDI igniter, and copper exhaust pipes contribute to its versatility and customizability.

When I first laid eyes on this R69 model, it was like being transported back in time to the era of classic motorcycles. The engine was a marvel to behold, with its horizontal cylinder block allowing for excellent air cooling performance and two symmetrical exhaust pipes being a hallmark of its design. The engine’s unique charm came from its ingenious structural design, and its all-metal construction made it as appealing as any showroom find.

Navigating the steps to start the engine felt like a journey into the heart of mechanical engineering.

One of the highlights of the R69 was its impressive specifications, such as its 3.2CC displacement, 13mm cylinder diameter, and 12mm stroke. But as with any product, there was the challenge of dealing with a slightly more complex start-up process when compared to today’s electronic engines.

Twin-Cam T124-Series Motorcycle Engine

I recently installed the S&S 124 cubic inch T124 low compression Long Block engine in my 2013 HD touring bike. The installation process was smooth and straightforward, but I did need to purchase an oil line kit separately. One thing I noticed right away was the high compression rate of 10.8:1, which really gave my bike a boost in performance.

However, I also encountered a slight issue with the engine’s breathers, which weren’t compatible with some aftermarket air cleaners.

The ease of installation is another pro, given its compatibility with stock and most performance intake manifolds.

However, one thing to note is that this engine operates at a 10.8:1 compression ratio, which might be a bit high for some riders. Additionally, there are no integrated fuel or ignition systems, which could be a drawback for those without the required performance upgrades.

Overall, the S&S Cycle T124 Long Block Engine offers reliable performance and a sleek appearance, but it’s crucial to ensure compatibility with existing performance setups before making a purchase.

Buyer’s Guide

When it comes to purchasing a motorcycle engine, there are several important factors to consider to ensure you’re making a well-informed decision. We’ve compiled a comprehensive buyers guide to help you navigate this process. From essential features to key considerations, you’ll find the information you need to make the best purchase for your needs.

Fuel Type

The fuel type of a motorcycle engine can impact its performance, efficiency, and operating costs. Common fuel types include gasoline, diesel, and electric. Gasoline engines are most widely available, while electric engines offer lower emissions and operating costs. Diesel engines can provide better fuel efficiency and torque but typically have higher upfront costs.

Size and Power Output

Another crucial factor to consider is the size and power output of the engine. Larger engines generally produce more power but require more maintenance and fuel consumption. On the other hand, smaller engines may be more fuel-efficient but may not provide sufficient power for high-performance applications. It’s essential to choose an engine with the right balance of size, power, and efficiency for your intended use.

Brand and Support

The brand and support of the motorcycle engine can significantly impact your purchasing experience and maintenance needs. Research the reputation and support offered by the manufacturer, as well as any potential compatibility issues with other components in your motorcycle. A reliable and well-supported brand can save you time, money, and stress in the long run.

Additional Features and Accessories

Some motorcycle engines may come with additional features and accessories that can enhance your riding experience. These may include electronic fuel injection, oil coolers, or even performance chips. Research and consider the importance of these features when comparing different engine options. Additionally, consider the availability of aftermarket accessories and parts, as these can further customize and improve your engine’s performance and longevity.


What types of motorcycle engines are available in the market?

Two-stroke engines are smaller and more lightweight than their four-stroke counterparts. They emit more pollution and require more frequent maintenance. However, they are popular among small engines and some motorcycles. Electric engines are also becoming popular, offering a cleaner and more sustainable option.

What are the key features of a good motorcycle engine?

A good motorcycle engine should be reliable, efficient, and offer good performance. The engine should be able to provide smooth power delivery, low fuel consumption, and good torque. Additionally, it should be easy to maintain, have good cooling, and provide a comfortable riding experience. A high-quality engine should also be durable and last for a long time.

Other important features include a balanced engine, which can prevent vibrations and improve the overall ride quality. A well-designed engine should also provide good acceleration and top-end speed, as well as a good power-to-weight ratio, which can help improve overall performance and handling. Finally, an engine should be compatible with the motorcycle’s rest of the components, including the frame, suspension, and wheels.

What are the differences between different types of motorcycle engines?

There are several differences between different types of motorcycle engines, including their construction, operating principles, and performance characteristics. For example, four-stroke engines have four strokes or stages in their combustion process, while two-stroke engines have only two strokes or stages. Four-stroke engines are generally more efficient and produce fewer emissions than two-stroke engines.

Electric motorcycle engines, on the other hand, do not have any combustion process at all. Instead, they rely on an electric motor to produce power. Electric engines offer several advantages, including cleaner emissions, quieter operation, and fewer moving parts, which can result in less maintenance.

What are some common problems with motorcycle engines?

Some common problems with motorcycle engines include overheating, low oil pressure, faulty spark plugs, and worn-out timing belts. Overheating can cause significant damage to the engine, while low oil pressure can lead to premature wear and tear. Faulty spark plugs can result in poor performance and reduced fuel efficiency, while worn-out timing belts can cause a loss of power and unusual noises.

Proper maintenance, including regular oil changes, cleaning the air filter, and checking the cooling system, can help prevent many of these problems. Additionally, regular tune-ups can help ensure that the engine is running smoothly and efficiently. If any issues do arise, it is important to address them promptly to prevent further damage to the engine.

How can I choose the right motorcycle engine for my needs?

When choosing a motorcycle engine, it is important to consider several factors, including your riding style, the type of riding you plan to do, and your budget. For example, if you plan to do a lot of off-road riding, a more powerful engine may be more appropriate. If you plan to ride mostly on the highway, a touring motorcycle with a larger engine may be a better option.

Additionally, consider the bike’s overall size and weight, as well as its performance characteristics, such as its acceleration and top-end speed. Finally, make sure to choose a bike that is compatible with your riding skills and experience level. Many manufacturers offer sport bikes and touring bikes with varying levels of performance, so it is important to do your research and choose a bike that is right for you.

Can I upgrade or modify my motorcycle engine?

Yes, it is possible to upgrade or modify your motorcycle engine, depending on the type of engine you have and the modifications you want to make. Some common modifications include adding a performance chip or exhaust system, upgrading the camshaft, and increasing the engine’s displacement. These modifications can help improve performance, efficiency, and overall power.

However, it is important to note that modifying your motorcycle engine can be complex, and it is best to seek the assistance of a professional mechanic or engineer. Additionally, some modifications may require changes to other components on the bike, such as the suspension or brakes, so it is important to do your research and ensure that any modifications you make are safe and compatible with your bike.
