Odd knocking sound from the front end Faser 2001

[Capt]

By chance earlier, I lent on the rear part of the bike causing the front wheel to rise off the ground, when I took my weight off I heard quite a load knocking sound from the front end as the wheel met the ground.  Rocking it back & forth on the centre stand the knocking sound is definitely there.

There is no play in head bearings & smooth from left to right, lifting the front end by the bottom of the forks to create the same rocking motion I can feel a mechanical knock same time as the knocking sound as the front wheel meets the ground. Off the centre stand holding the front brake pushing the forks up & down good smooth operation though the knocking sound is still there but a little less so it’s not the pads.

Forks had a KTEC upgrade last year along with head bearing greasing etc & have noticed nothing until today.

Could it be just some play in the fork internals causing this when they go from unloaded to loaded even with just the bikes weight on the centre stand?

Any ideas as it does not sound right?

Recheck your steering head bearings.
What you describe is exactly what I was experiencing even after renewing them & torqueing to yams specs.
A further little nip cured it.
Of course don't discount other avenues.

KTEC tell me it’s perfectly normal & nothing to worry about, they take many calls of the same nature.  Apparently it’s the main spring twisting as the loading starts & the noise I am hearing is either the spring moving on the pre load adjuster or hitting the internal tube.  Having only covered about 500 miles nothing could be worn!
I kind of accept this is the cause of the noise however; it still seams wrong its happening.
