hi my 80cc has only 200 miles on it. with the clutch lever out and pushing the bike forward the engine does not turn over. Yet when pushing it backwards the engine turns over. is this a clutch problem?
 
Does the chain (or sprockets) have any damage???

Look all over... There has to be a reason why the engine turns one way (& not the other).

You've been riding it for 200 miles (so I'm assuming that you know that the engine should be hard to turn because of compression)??
 
I can push the bike forward real slow and the engine will turn over once every 10 ft. pushing it backwards it contantly turns over. its really wierd. I checked the sprocket nut, it's tight.
 
took of clutch cover. Smaller gear does not move with clutch disengaged. Yet like I said previously when pushing it forward the small gear will turn and then that's when the engine turns over rolling forward
 
Alex it sounds like your clutch is slipping, remove the screw that locks the clutch plate then lock the clutch handle in ( it makes turning the flower nut easier) then turn the flower nut clockwise a notch or two, then put the screw back in and check it. Keep adjusting till it doesn't slip.
 
thank you for your help. I haven't adjusted it yet because I stripped the screw yet. lol. I'm waiting for an extractor set to come in the mail.
 
You have 3 key ways in the drive line, one under the chain sprocket and under both gears on the right side. See if you can determine if either has broke.
 
Look at the small gear first, it’s the easiest to check. All three keys should be the same.
 
Each gear or sprocket has a woodruff key under it in a groove cut in the shaft and gear or sprocket.
 
Here are pictures.
