Hi, being real new to Honda scooters, and this might be a stupid question but what is a Lifan engine? Is that something HOnda builds as a replacement engine for old scooters? and it has the gearbox incorporated into it?Sorry for being denseMichael

Its a two stage clutch. It has much smoother shifting.
The New Honda supercub 110cc has the two stage clutch. here is a cut a way of it.

My scout 110cc does not vibrate much at all. I have two of the 110cc engines. I bought the last one Fly had new in the box just before they closed.

It vibrates so much at idle that I feel like I'm riding a vintage sport bike. Kinda gives me a good feeling, but also can be annoying at times when your feet vibrate too much while riding at slow speeds.

With a small bike like a C70, you need all the power you can get if you ever find yourself in a compromising situation. I would also get a slightly larger rear tire, for more stability. I went one size up on both front and rear, but now my speedo lies to me, so I need to get that changed back to stock size.
