As this thread is very timely for me, I'll hop in, if you don't mind.
I recently purchased a K8, and decided to replace the worn chain, and found a large hole that had been covered with a coke can and fibreglass!
I can source a K6 cases in good nick, and my question is will my K8 internals fit into the K6.
I have made a better repair that is ok and oil tight,so the bike is rideable now, but will jump on the cases if the collected wisdom on this invaluable site is to go for it.
Thanks in advance for any suggestions/ help.
