I have a set of '09 Pike air U-turn forks. When i set the dual air pressures & the rebound etc all is fine, but if/when i dial the forks down to a shorter travel i get a horrible 'clonking' top-out sound – is this normal or is something wrong?

No idea, mine are coil.

But, check out this retro Pike porn…

I like the way the voiceover lady says 'aggressive sketchy situations' in her sexy American cyborg voice.
