I’m asking about motorcycles specifically but it goes for all vehicles. Why/How in a v-twin engine if CC’s are very close and the same manufacturer exhaust is installed on each bike the sound is different? Is this done with timing or are there other internal parts that cause this?
In: Engineering
V-twins usually have a longer stroke than inline engines which affects exhaust gas velocity and pulse. But valve timings, overlap, etc will also have an influence on the pitch.
