Transmission issues
#12
The 'whirr' doesn't create an engine stall. It just occurs for a few seconds after letting off the throttle and slowing (clutch out, in gear, any gear). It seems to go away or become much quieter when the bike is warmed up.
The clunk-stop has only happened 2 or 3 times, was more than a month ago, and isn't something I've been able to purposely recreate. As I was thinking about it more, the bike may not have been in neutral, but instead in gear with the clutch lever pulled in. Idle could have been low.
I'll try turning the engine over to listen for ACR, and check the idler gear.

The "whir" noise you hear any chance it's your timimng chain as I went to the Krieger tensioner and my bike lost the 5K clatter but makes a "whir" until the engine is warm and then all is right with the world.

If it is the tensioner you maybe fine on the adjustment as from what I understand it will be noticable when cold but as it warms the noise goes away.

Thought about this a little more. Can't be the tensioner. If I immediately pull in the clutch lever and let the engine slow, or rev it, the whirr doesn't change at all. It seems I should be looking at the idler gear first. Thanks all for replies.

On the 'whir', just check there isn't a kink in the front brake hose plastic sheath, or you handlebars aren't restricting the upward movement of the hose when you brake. Mine did this when I moved my GPS cradle, it put a kink in the hoses plastic cover and when i slowed or braked, it 'whired' when it rubbed on the front tyre.
