What happened?

The problem: Letting go of the clutch no longer reengages the chain with motor.
How it started: I was holding on to the clutch at a red light and twisting the throttle to help keep the motor running. (I probably got carried away with the vroom sounds and twisted it too much/long)

So what's up guys. Is the motor busted? Is it a quick fix? Any help would be appreciated .

It's a two stroke. I'll check it out later but what I can tell you is that the bike moves freely with the clutch unheld.

A little more about this: I realized something was wrong when the throttle failed to accelerate the bike. It was on and running but twisting the throttle would only make the the engine rattle and not accelerate the bike. I brought the bike to a complete stop and it remained on (It's supposed to turn off when I bring it to a stop). I had to push the kill switch to turn it off.

Essentially the bike is acting as if the clutch is being held down when it isn't.

Loosening the arm is the first thing I'll try. It seems silly though, should I really expect it to have gotten tighter with time?

Popping the clutch sounds like that may be what happened... Well, this is will give me a chance to learn how the motor works at the very least.

I'll go play around with it now.

Here's what's up. I opened up the clutch plate and and loosened the clutch. Everything seemed fine after that. The "cough" that the spinning the back tire gave to the motor was back. I was able to turn the bike on and ride for a couple miles or so. Then the problem came back but this time removing the clutch didn't solve the problem at all.

I opened up the plates as you guys said and yeah, all the gears are moving accordingly. It's that "cough" that I'm missing to turn the thing on. It sort of coughs when I move it slowly but when I move it quickly it just gives me steady resistance.

So I have to figure this out. Am I using the bike properly? Aren't I supposed to grab the clutch to idle at street lights and stuff?
