I guess that size does matter. I have a 1984 GR650 Tempter. The service manual says that I need a DID 50HL drive chain. I had difficulty locating one online. Bike Bandit sold me a DID 525 VX series X ring chain. It is too big for my sprockets. That is to say that the pitch is too long. Can anyone point me in the right direction? Thanks!
