Is this normal?(Fixed Video Is Up)

Have a look at this video. My bike is on a stand and the chain seems to skip. Not sure this is normal. I have never had the bike up on a stand with it running in gear. I was checking the new oil seal around the font sprocket shaft to make sure it didn't leak when I noticed the chain thing Edited by YZPaGuy

Yes, it's normal. No, it's not skipping.

What's happening is due to the engine being a single cylinder. It speeds up when it fires, and slows down everywhere in between, especially on the following compression stroke. The wheel is a little bit immune to this because it's kind of a big flywheel in its own right, but none the less, it gets suddenly accelerated and decelerated by the fluctuations in engine RPM, and that's what you're seeing in the chain.
