broken chain

my bike is eating my chain how do I fix that.

if you're using a Chinese 2 stroke, invest in a #41 chain from tractor supply. the chains that come with the kit are garbage. also check that your engine to sprocket alignment is right and your sprocket is as close to perfectly true as possible.

thanks will try think tensioner may be moving on me too

do away with the stock tensioner if you can. in my opinion they're full on dangerous.

sounds like the chain is climbing the rear sprocket teeth - watch it as you turn the wheel slowly to find out why - often, it is because the tensioner is not feeding the bottom chain run directly onto the rear sprocket, or you have the chain too tight

standard chain & tensioner work just fine when done right
