Q: What do you call a Commando with a 800rpm tick-over...?
A: A cam grinding machine...!
At my local vintage club meet (which I only get to occasionally) the fashionable thing to do is start your engine from cold and let it tick over. The keen ones spend hours in the shed tuning their bikes for the slowest tick-over they can get.
They love to start up their cold bikes and show off their super slow tick-overs, with the bikes sounding like stationary engines at a steam fair as they spend ages togging up to ride off.
Most of ‘em insist on using cheap shite oil too “that synthetic oil is too thin boy”. I just look on, say nowt, and wince at the poor suffering cams and followers!
To be fair though, the way some of ‘em ride they’d probably not even notice if the cam lobes were half gone...
