He was on a number of Yahoo groups/forums & on Britbike & Norton & seemed to be banned from a lot for being contentious.
From memory, his main grouse was about the grades and makes of belts being sold and whether they should be run dry or lubricated.
There was one grade of belt that was supposed to run dry, but could tolerate oil, but better without.
Ructions ensued whenever he posted a message.
He was actually very helpful & we exchanged many helpful discussions.
