New to Motorized Biking - Engine Noise 70cc vs 80cc vs --cc ??

[jnanasakti]

I did a quick search and didn't find a topic specific to this question, so I am wondering what the general thoughts are on engine noise. I understand there are many engines out there with differing levels of ccs, but are the 80cc engines noisy? I would go with a lower cc engine if it made any difference in noise, if noise is any much of an issue to begin with.

there ALL 67CC
all of them
70cc AND 80cc are 67cc

Seems that different engines are noisier than others with not much corolation as to who sold them or what they are claimed to be.

There are a lot of ways to quiet a noisy bicycle engine, all easy and cheap.

Look over to the far left of this page or do a search for "motorized bicycle engine kit" on ebay.
