Sorry, I guess we did, but I sure learned a lot. and my opinion would be to fix it up the way it is and not put in a replacement engine. but that is just me, I like to restore things and not mod them.

You guys hijacked my thread!
Getting back on track, any other thoughts on whether to switch to the Lifan? I'm now leaning in that direction.

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.
