I suspect the cause of "Thread Drift" is related to the cold winter nights - as many of us are not actively doing much bike work in the cold we trawl this site looking for things to say or comment on.
One mention of the likes of Pink Floyd - we are drifting further than Phil on his Yacht when the wind has dropped. 
I managed to get out on my bike today, for a post carb synch shakedown. Ran very well. No bogging down, no oil leaks and, for the first time since I've owned it, all the plugs look similar, clean and non-sooty. The bike has fought me a lot of the way, so I'm not assuming anything just yet. But I allowed myself a self satisfied little pat on the back, for now.
p.s. I hung the Sealey tank from the rafters about a foot above normal tank height. It worked well.
p.p.s. The Clash and The Cure, never really got Pink Floyd
