bike will start but wont drive

[rat bike]

Howz it goin everyone I have a about a hundred miles on my bike and while I was riding the other night something made a loud noise down by the clutch. So I pulled over to see what it was and couldnt really see anything cause it was dark out. So I tried to start it back up and it fired but wont drive I can run and rev the motor but I dont get anything to the rear wheel. I want to ask and get a few options or ideas before I tear into it. Any ideas would be greatly appreciated.

Welcome,rat bike.If you have clutch to start it you should be able to drive it.
If it happened to me I would take off my clutch cover and see if anything was up in there!Kip.

if this is a 4 stroke with pull start then something in the clutch or reduction drive broke, if it's a 2 stroke bump start i don't see how that would be possible.

We need more information, please. 2 stroke or 4? Pull start? Centrifugal clutch or manual?
Provide just a little more info and we can offer some suggestions.
I'm betting it is a 4 stroke with a pull start. If that's the case then follow Camlifter's advice and look for broken parts in the clutch. My guess is a clutch bell that has sheared on the shaft.

hey everyone sorry I was short on info it was late and I had just walked a couple miles pushing this bike to get home. so today i pulled off the clutch cover and found my problem, it was the small gear that rides on the clutch gear. that little gear just snapped in half. Im guessing it was able to jam up enough to start but when the motor was running there was no woodruff key to turn the large clutch gear. so I guess Im gonna order a new one and get this bike on the road again, any pointers on putting the new gear in oh and also the motor is a 66 cc with a clutch not centrifical.

wow, i'm amazed it would start like that. it's an ez fix, put a little dab of grease on the gear teath when you put the new one on.

well i found out the hard way that grease on the clutch and the small gear is now something to add to my matinence list since i put about a 50 or more miles on this thing a week. but now im checking out the plug in this thing and its really dry and has a little build up on it. the plug is the stock plug that comes with the piston bikes kit, its the one that has 3 prongs going to the electrode. the bike runs great gettin up to 30 mph on level ground sometimes 27 to 30 even on slight hills. i thought these plugs were supposed to be a little wet and looking kinda golden in color. my thoughts are to raise the needle in the carb but before i do i want to make sure thats right.
