Pros of buying a Yamaha RT1M/RTMX cylinder head:1. Originality: Buying a new-old-stock (NOS) cylinder head for your 1970 RT1M or 1971 RTMX ensures that you're getting an original part that matches the specifications and quality of the original manufacturer.
2. Performance: A new cylinder head can potentially improve the performance of your motorcycle, as it can help to reduce engine knocking, improve combustion, and increase horsepower.
3. Durability: A NOS cylinder head is likely to be in better condition than a used part, as it has not been exposed to the same wear and tear as a used component. This can help to extend the life of your engine and reduce the likelihood of future repairs.
4. Availability: NOS parts can be harder to find than used parts, but they can be a worthwhile investment if you're looking for a high-quality replacement part for your motorcycle.
Cons of buying a Yamaha RT1M/RTMX cylinder head:1. Cost: NOS parts can be more expensive than used parts, as they are harder to manufacture and distribute. This can make it a more costly investment, especially if you're on a tight budget.
