I may be missing the whole point.
The kdx is pretty noisy, and there is a distinct racket in the clutch when the bike is running in neutral, clutch not engaged (lever not pulled). If that is the issue, then, as rob says, there is no issue.
I assumed this to be a new noise..and gears '..still trying to engage...' is not how I think of the 'normal' kdx noise.
Run a good 850ml or so in the tranny for starters. That will quiet the 'normal' noise down.
IF this is not an acute noise (acute='sudden onset') and you do have an acceptable (re: the 850ml noted above) oil volume, and your clutch operation is satisfactory.......then just ride the thing! (like rob already said)
