I haven't used a 49cc engine, so I ordered one from Powerking. I'm wondering which engines are the smoothest running with the least vibration, the 49cc or the so-called 80cc? I could be wrong, but I believe both engines have the same stroke, but the bore is different. If the engine was designed as 49cc, and they increased the bore, then perhaps the 49cc engine is smoother and better balanced?
Which engine is smoother with less vibration? Thank you.
