riding for the first time and my motor is locked up

[erickster]

I was riding my 70 cc bike, and as I rode, my chain popped off the sprocket. I thought it was a little weird, but I thought, well-- somehow it came loose and popped off. I re-attached it to the sprocket, and tightened it again. I tried to roll my bike, and the back tire was locked up. So I thought, "maybe I left the clutch up", nope. I don't know what happened. Clutch down, or up, it's just locked. Any ideas??? I haven't ridden my bike for more than 30 yards yet.. ha.

So the back wheel was locked-up.....what about the engine...does that move freely?
Please explain in more detail(pics if possible) about what's happening.

BTW...u said "30 yards yet"....so it's a brand new build?

Take the sprocket cover off and check the chain. The chain can jam up inside the cover.

Take the sprocket cover off and check the chain. The chain can jam up inside the cover.

That would was my first thought too.

Since that was the problem(chain jammed up inside the cover) try letting the clutch out quickly NOT dropping it.
