I fired it up started second prod!

I then need to move it. Engaged the clutch selected first gear and CLUNK!
very loud as the gear engaged.
However no grinding or more mysterious noises and i moved the bike etc.
i didnt notice the clutch dragging.
So my dilemma is this. was the loud clunk as I engaged first gear normal.
Was it because the bike had been stood a while (10 days since fired up and much longer since gears were selected.) everything is cold.
Or more likely is it the 'echo' of the garage and me being hyper critical
