No you don't have to do anything with the clutch assembly to swap out the front sprocket.
The clutch is on the exhaust or right side of the bike..
The front sprocket is on the left or kick stand side of the bike..
Remove the four 10mm (if I recall correctly) bolts from the sprocket cover... don't F up the speedo pickup. Then go at changing the sprocket.
You will need a impact wrench to get it off.
But how old is the setup? A new front sprocket on a old chain isn't always good!
