Mikuni 32a-139 Carburetor - compatible with 1979-1980 Kawasaki Invader

Introducing the Mikuni 32a-139 carburetor, a fine replacement or upgrade option for the 1979-1980 Kawasaki Invader motorcycles. Mikuni, a renowned name in the world of motorcycles and automobiles, has designed this carburetor to deliver impeccable performance and reliability.

This Mikuni carburetor is equipped with a 32mm throttle body. The throttle body diameter is an essential aspect of a carburetor, as it governs the volumetric flow rate and, consequently, the engine's power output. In simpler terms, the larger the throttle body, the more air and fuel the engine can draw in, leading to increased power and performance.

The Mikuni 32a-139 carburetor arrives in a limited interceptor configuration. The interceptor setup, also known as a velocity stacks or high-performance setup, is designed to improve the engine's power output and responsiveness. These stacked intake trumpets, or velocity stacks, create a velocity tunnel effect, smoothing the intake airflow and feeding the engine with a denser charge.

This Mikuni carburetor features six 19mm jet circles, which are used to meter the fuel flow for an efficient combustion process. These jets are carefully calibrated to ensure precise fuel delivery, resulting in a smooth Idle and powerful riding experience.

Another notable feature is the presence of the secondary needle position (SNP) choke system. This system comes in handy, particularly during colder weather, helping you start your Kawasaki Invader more easily. Once the engine is up to temperature, the choke can be switched off via the lever located at the bottom of the carburetor.

Mikuni carburetors are well known for their sturdy construction and long-lasting durability. The Mikuni 32a-139 variant for the Kawasaki Invader features precision precision-drilled metering holes, CNC-machined components, and Japanese O-ring seals. These details contribute to the carburetor's robustness and reliability, making it a solid choice for classic motorcycle enthusiasts seeking improved engine performance while maintaining an authentic ride.

Installation is made easy thanks to the Mikuni carburetor's compatibility with the factory Kawasaki Invader airbox and intake system. This OEM-like fitment minimizes the need for extensive modifications during the installation process, making it a hassle-free upgrade.

In summary, the Mikuni 32a-139 carburetor represents an excellent alternative or upgrade for motorcycle enthusiasts looking to boost the performance of their 1979-1980 Kawasaki Invader. With its large 32mm throttle body, interceptor setup, precise fuels jets, and SNP choke system, this Mikuni carburetor delivers increased power, superior responsiveness, and smooth engine performance. Its well-crafted design, durability, and OEM-like fitment make it an excellent investment for those who take pride in their classic motorcycles.

Mikuni 32a-139 carbs, manufactured by Mikuni for Kawasaki Invader motorcycles produced between 1979 and 1980, are popular among classic bike enthusiasts for their durability and performance. These carbs offer both advantages and disadvantages. Here's a breakdown:

1. Authentic and Original: These carburetors are the original components used on the Kawasaki Invader model and contribute to the bike's vintage charm. Installing these retain the authenticity and originality of the motorcycle, which is a prime consideration for collector's and originality enthusiasts.

2. Reliability: Mikuni has a reputation for manufacturing high-quality carburetors known for their durability and precision. Despite being decades old, these carbs can still deliver consistent fuel-air mixture and power delivery if properly tuned, reducing the need for frequent maintenance or repairs.

3. Flexibility: These Mikuni 32a-139 carbs offer a broad adjustment range, allowing riders to fine-tune the engine's performance to suit their specific riding styles or conditions. Fiddling with the mixture, idle speed, and main jet can significantly impact the bike's power delivery, throttle response, and fuel efficiency.

1. Old Technology: The Mikuni 32a-139 carbs are quite old and may not provide the same level of efficiency and power delivery as modern ECU-controlled fuel injection systems. They can be harder to tune and may lead to uneven fuel mixture distribution that could potentially harm the engine over extended periods.

2. Manual Tuning: The need to manually adjust and fine-tune these carbs can be a time-consuming process, especially for those less experienced with carburetion or who simply prefer a more straightforward setup. Modern fuel injection systems offer far more precise and consistent fuel delivery without the need for manual adjustments.

3. Obsolescence: Older carburetors like the Mikuni 32a-139 are becoming increasingly costly and challenging to source as they are no longer produced. As they age, the demand for replacement parts and tuning expertise increases, potentially adding to the overall cost of owning and maintaining these carbs.

The Mikuni 32a-139 carbs for the Kawasaki Invader are an excellent choice for classic motorcycle enthusiasts who value the authenticity, charm, and flexibility of carbureted engines. However, their age and manually tuned nature come with inherent challenges, such as potential decreased efficiency and costly replacement parts. If the bike is a daily rider or a high-performance track weapon, one may want to consider alternative, modern fuel delivery systems to ensure optimal power output, reliability, and convenience.

For motorcycle enthusiasts seeking the benefits of the Mikuni 32a-139 carbs while minimizing some of the associated challenges, it is recommended to properly maintain these carbs to keep them in good working order. This can include regular cleaning, adjustments, and careful tuning to ensure optimal performance. Consulting experienced mechanics or joining a community of Mikuni 32a-139 users can provide valuable insights and support for those new to this carburetor system. For those prioritizing convenience, modern fuel-injected alternatives should be considered.
