    I have read in this forum and others that there is no real 80cc engine.
    It is only 65cc engine and close to that.

    Can somebody tell me why this lie keeps going around?
    People who think there bike is 80cc will get 80cc boost bottles and 80cc tuned exhaust but the engine is smaller then that.
    I got a 80cc boost bottle and I am so regretting it.


    Thanks for any info.

    Same reason Sears calls their shop vacs and air compressor motors 120V, 38 horsepower.

    Marketing baby!!!

    Because if you keep repeating a lie long enough, it will become true?

    You would have regretted the boost bottle anyway.

    38 Horsepower??!?!!? ROTFL

    That's like 28,348 watts or 236 amps!

    I think the reason they claim these motors are 80cc is that they add the displacement left in the concave head to that of the actual piston movement in the cylinder.

    This kind of trickery is almost on par with what we get from politicians and their blowhard promises.

    Somebody had a hilarious saying about Sears motor ratings - I wish I could do it justice. But you got my point. It seems to be common with electric motors. 8 HP treadmills, 14 HP vacuums, etc

    That's easy to answer everyone likes to hear bigger numbers. They think they are getting something better. It's the same thing with the computer industry as well. It's not always about the number either. But what can you do?

    Hey Neat times that depends on the size of the pictures. And as far as the size of the hard drive it is always a little bit smaller than the actual size. As far as the tech telling you it was wear and tear I highly doubt it on a newer system like the unless it was defective. I have had newparts bad right from the box hope that helps you The tec that gave you that information cant be a very competant at his job. Or he is a person that likes to rip you off.

    If I called it a 65cc, no one would probably know what I was talking about. How about calling it an 80-65cc?

    Ok, I am talking to this guy who is selling me this engine HT and he is saying its 80cc when I told him I know they do not make an 80cc. Anybody know where to get proof that there is no 80cc engine.

    Thanks

    They are 80cc if you measure the combustion chamber volume....which is not a standard way to measure swept volume.

    He is therefore mis-informed and/or ignorant, and I don't mean that in a mean way.

    So the biggest engine out there for this bike is a 67.5cc engine? I need to know to tune my exhaust and boost bottle. Ya I have heard lots about this bottle but want to try it myself with the correct cc size to see any difference.
