The green flag sets me free
This has got to be the single largest mystery in the motorcycle world and as hard as I have tried to leave this subject alone I have to hear what all of you think about where this NON EXISTANT part could have originated and why so many people actually believe in them?
Let me explain a little further...As a motorcycle enthusiast I have been hearing about "power bands" since I was a child...as a dirt bike/atv rider the first thing I always hear when someone starts asking about a machine is "what kind of powerband does it have"...or I see bikes for sale listed with wording like "new powerband" or "aftermarket race powerband" etc....as a shop owner people bring their machines in and when I ask them what it is doing I hear "I think the powerband is broke"...
As in a physical part a "power band" DOES NOT EXIST! I have had this discussion with many close friends and have yet to find anyone that actually knows this...? As the belief in powerbands as an actual part is so great and most all motorcyclists believe in them I find myself having to open this discussion for input from fellow members!
What is a powerband...? Not to be confused with a power valve which acts to vary the height and width of the exhaust port, a "powerband" is a measurement and is not a part and is the range of rpms in which the engine makes good power. Say a 2 stroke engine, just for example, has a range of 0 - 10,000 rpm and makes a lot of power from 6000 - 7500 rpm...then from 6000 - 7500rpm is the "powerband".
The only thing that I can think of as reasoning behind this belief in a non existant part coming to life is that a 4 stroke engines makes good power all the way through the rpm range and gradually increases and falls where a 2 stroke engine makes nearly no power through most of its rpm range and only makes strong power through a short rpm range and when you come into this rpm range it makes a lot of power all of a sudden and feels like a burst of power...this burst of power is what everyone refers to as the "powerband kicking in" which in the sense of using the terminology that a powerband is a measurement is correct...using the term "powerband" in referance to an actual part or some kind of turbo or supercharger is wrong.
Like I said I just thought it was agood subject and am curious as to what you think! I have seriously only come across a very small group of people that actually know this! Curiously many 4 stroke bike builders and engine professionals are not even aware of this information so I have to know what your thoughts are on this subject! And for those of you that did not already know this go have some fun and tell your buddies that your truck, car, lawnmower, and weed eater have a powerband!
