Review YAMAHA Nos Genuine Ignition Point Contact fits RD250 RD350 R5 1970-75

The Yamaha RD Series motorcycles, specifically those from the 1970-1975 era including the RD250, RD350, and RD4 models, are legendary machines in the motorcycling world. These bikes gained immense popularity due to their agile handling, powerful engines, and distinctive design. One crucial component of these motorcycles is the ignition system, and more specifically, the point contact ignition system.

The 278-81621-20-00 NOS (New Old Stock) ignition point contact is an essential replacement part for these classic Yamaha motorcycles. This ignition component is designed to generate a spark to ignite the fuel-air mixture in the engine's cylinders. It's important to note that an ignition point contact that has worn out or has become faulty can lead to a host of issues, such as poor engine performance, difficult starting, or even engine damage.

The point contact ignition system consists of a series of points and a condenser. The points, which include the contact breaker points and the center electrode, are responsible for opening and closing the electrical circuit to the spark plugs at the right moment during the engine's combustion cycle. The condenser, on the other hand, helps maintain a stable voltage level in the ignition system for efficient and consistent sparking.

The 278-81621-20-00 NOS ignition point contact is manufactured to Original Equipment Manufacturer (OEM) specifications. It is made of high-quality materials that ensure reliable and long-lasting performance. The points are precision machined and chemically treated to provide accurate and consistent electrical contact. The contact surface is designed to minimize wear and ensure a clean, sharp point for optimal sparking.

Incorporating this NOS ignition point contact into your Yamaha RD250, RD350, or RD4 motorcycle will not only restore its performance to original factory specifications, but it also provides an opportunity to enjoy the bike as it was meant to be ridden with the classic feel, sound, and character that only these iconic bikes can offer.

Installing this part is a relatively straightforward process. You will need to remove the old ignition points and condenser, clean the distributor cap and rotor, and install the new components. It is recommended to consult your motorcycle's service manual or consult with a professional mechanic to ensure a correct and safe installation.

In summary, the 278-81621-20-00 NOS ignition point contact is an essential replacement part for Yamaha RD250, RD350, and RD4 motorcycles from the 1970-1975 era. This high-quality component is designed to restore your bike's original performance, providing you with the classic riding experience that these machines are renowned for.

The Yamaha RD250, RD350, and R5 motorcycles produced between 1970 and 1975 are classic two-stroke bikes known for their power and agility. When it comes to replacing or upgrading the ignition system on these bikes, point contact ignition (PCI) can be a popular choice due to its reliability and performance benefits. Here are some pros and cons of buying a Yamaha 278-81621-20-00 nos (new old stock) PCI ignition module for these motorcycles.

1. Improved Performance: PCI ignition systems provide a more consistent and reliable spark, which can lead to improved engine performance and power output.

2. Reliability: The simplicity of the point contact ignition system makes it more reliable than other ignition systems. There are fewer components to fail, and the system is less susceptible to electrical interference.

3. Cost-Effective: Compared to other ignition systems, PCI modules are often more affordable.

4. Easy Installation: Installing a PCI module is generally a straightforward process, making it a popular choice for DIY motorcycle enthusiasts.

1. Limited Adjustability: PCI ignition systems do not offer the same level of adjustability as other ignition systems. This can make it more difficult to optimize the ignition timing for different riding conditions.

2. Limited Compatibility: PCI modules may not be compatible with all motorcycle models, and it's essential to ensure that the specific module you're considering is compatible with your Yamaha RD250, RD350, or R5.

3. Potential for Carbon Build-Up: Due to the nature of two-stroke engines, there is a risk of carbon build-up on the contact points of the PCI module. This can lead to a decrease in performance and reliability over time.

The decision to buy a Yamaha 278-81621-20-00 nos PCI ignition module for your Yamaha RD250, RD350, or R5 motorcycle depends on your priorities and budget. If you're looking for improved performance, reliability, and a cost-effective solution, a PCI ignition system may be the right choice for you. However, keep in mind that PCI modules offer limited adjustability and compatibility, and there is a risk of carbon build-up over time. Ultimately, it's essential to weigh the pros and cons and consider your specific needs and riding style before making a purchase.

If you decide to purchase a PCI ignition module for your Yamaha RD250, RD350, or R5 motorcycle, make sure to choose a reputable supplier and ensure that the module is compatible with your bike. Additionally, be prepared to perform regular maintenance to keep the contacts clean and free of carbon build-up. With the right care and attention, a PCI ignition system can provide you with reliable and improved performance for your classic two-stroke Yamaha.
