Default Re: 49cc vs. 66/80cc True or False?

I have built several 48cc engines that run well but they are not equal to a 66cc engine. The advantage the 48cc engine has is less vibration, my 48 is much more enjoyable to ride than my 66cc bike. Its probably due to the lighter piston, the balance is much better on a 48cc.
Your results may not be the same,Greg
