Hi Wazzbat
Yes they are brand new chains. I have purchased a quantity of chain and will be making up a few sets of chains for the 45.
As Deejay said the primary chain is a different type to the roller and clutch chains.
I have a few sets of Primary chain (Goes from top sprocket to roller sprocket) Made up ready to go, with new link and I have advertised these for $20.
Hopefully by the weekend I will have some full sets (all 3 chains) ready to go and I expect them to be $50 - $55. Im not doing this to make money and it is not going to be a long term thing. Just re-couping some costs from my 45 rebuild and offering equally good chains at a reasonable price.
