Need help with Go Kart question!!!

[Zen_Life]

Idk what that part is called I think the sprocket?? But it came loose and now the chain is loose and comes off when I do hard turns on the go kart. I’m curious how do I go about fixing that?

Not familiar with that setup, though it looks like it doesn't have a clutch??

Ours has a bit larger "sprocket" assembly in that spot that allows the engine to idle without the go kart moving forward...

Can you take another picture a little wider? It doesn't look like the drive sprocket, kind of looks like a bearing fell apart that holds that shaft in. Is there another 2 sprockets and chain on the other side of that motor?

Missing a bearing? Dual drive? Clutch opposite side?

If it is not a dual drive I would guess its the centrifugal clutch. But i could be a failed bearing. Just start taking it apart.

That looks like a countershaft with a keyed sprocket and a failed roller bearing. Centrifugal clutch would be on the drivers (left) side. Whats pictured is on the right. Looks like all you need is a $5 bearing. Probably a 6203.

Looks like a gear reducer of some sort. Mine had two different sized gears on the same side as the clutch. I removed it, flipped the clutch, and now it does about 40.

Bearing definitely failed on yours.

Yeah I’ll take some better pics tomorrow when I get home. I’m new to go karts lol. On the other side is just a belt.
