Klunk is good.
It means that the dogs have fully engaged and you're ready to go.
Trying to quiet the cluck by foot shifting slowly or not completely only damages the dogs and leads to transmission damage.
If you keep the input and ouput shafts moving at close to the same speeds, the less the cluck. That means a brisk upshift, not speed shifting, but not loligagging either. On downshifts, revving the engine to match speeds will help too. When the bike is stopped, the output shaft is still and the engine/input shaft are rotating at idle speed. Fully clutching the bike will slow the input shaft a little, but it still moves due to some clutch drag. Holding in a couple seconds fully allows the shaft to slow maybe a little more and may help with the clunk, but don't ride the clutch, it'll wear out the bearings.
