1978 CB750K Chain and Sprocket replacement?
« on: January 15, 2021, 01:56:00 pm »
The rear sprocket is wearing thin on my k8 cb750 and I'd like to upgrade the chain and sprocket to 530 from the stock 630. Problem is, the k8's the neglected middle child of the cb750 family and I'm having troubling finding new parts that will fit.

Does the k8 use the same chain and sprocket as the f models from the same year? What will work for my bike? O ring or x ring? Its a daily driver so I'm looking for performance and longevity over frugality. Thanks!
