Re: 50cc vs. 66cc
"There's no replacement for displacement"
There is paper power and Real-world power. Lots of people claim that their 49cc are just as fast or faster then some of the bigger 66cc's. This is simply not true and I laugh to myself. Stock vs stock the 66cc will win, modified vs modified the 66cc will win. Engines with a bigger displacement will always have better speed and power to get up them hills. The same law of physics applies here just like in bigger motorcycles.
Vibration can be caused more if the engine is poorly mounted, my grubee doesn't vibrate till around 35mph.
