Irregular Knocking vibe from front

[unfazed]

Ok, with the help of a GS rider holding the back down, checked the head stock bearings this morning and no issue there. No play and as smooth as you like.
Now I know I failed on 2 counts a) Letting a GS rider touch my bike b) talking to a BMW owner - buuut he was the next guy to turn up at the bike bay. Nearly fell over when he spoke back to me and said yes he'd help  :eek  :lol

We going wheel bearings now?

Thats it! No more help from here :'( :'( :'(
