Just been out into the garage to check my own 400, the bottom bracket is correct for a 400/4.
Jumping in here, I'm after one or two of the short CB500/750 rear stems and rubber mounts if anyone has any.No doubt I'll post a desperately seeking in a couple of months as better weather approaches. (Please...)
