Clutch Bike rolls freely with clutch lever open

[crassius]

those chain marks on cover usually mean that the sprocket has come loose - if so, then the key that locks it is gone or broken

Well I managed to get the cover off.

I'm guessing its a bit of the inside of the cover got shredded by something. Sorry for the blurry pictures, my camera is a potato

KellT I have to apologize for my trouble shooting described in reply 9. I updated it to be more accurate. I just noticed the error. Of course the drive gear is going to spin when the bike is pushed forward, It's hooked to the chain. The shaft would be stationary with a bad key at this location. Again sorry.

 

[KellT]

yup- the pin in the center of the drive sprocket comes out freely. I can replace the key, but I dunno why this happened in the first place which is kind of worrisome

 

[KellT]

Well ain't this a B.

looks like a chunk of the shaft was gouged out either when the key broke or to begin with which is what caused the key to break.

Hmmm..I guess I can use this for parts, or break out the welder and try drop a bead or bust out the jb weld and redneck it.

What d'yall think? Again I apologize for my potato pictures. I might just invest in a camera from this decade.

The slot on the left is the key slot

You can get a new clutch shaft assembly from Kings motorbikes for 14 bucks or just the shaft itself for 2.50 They are not that hard to replace. Probably need a new key and cover. Don't think the JB weld is the answer here. I guess if you where considering welding it you could tighten it back on with the nut then remove the nut and weld the gear to the shaft. Don't think that is the best idea either. Usually a lot of flammables in that area. Probably have to go slow so you don't melt the bearing seals and the grease in then. A lot could go wrong without proper prep. and it would be a b**ch to burn your bike down for a 2.50 part.

look around the board and you'll see a lot of this same problem lately - some factory is failing to get these on tight

this never used to be so common a problem

what kit did you buy?

It was an ebay special. However I've since gotten a kit from BEKITS.com. It is SO good, i prolly will never buy any other type unless the quality starts dropping. This engine will be shelved for parts. It's a 38mm half breed per Fred's designations. I could get the premade clutch bar and put it in but I doubt it will perform anything like the bekits engine pk 80.
