Morning.
I've done it a few times and it's not that difficult as long as, as always, you have the right tools. Firstly clean the whole area of the crud that can collect over time around the front sprocket - removing chain guard, lower chain guide & clutch slave cylinder required. Firstly I swap out the front sprocket (loosen it before removing the old chain as it needs to be in gear with the rear brake on to loosen to the mounting nut) then I angle grind the old chain off, just cut one of the links in two. Then tie wrap the new chain to the old one and pull the old one through dragging the new one around the front sprocket. Replace rear sprocket, join two ends of the new chain, tighten everything up and Robert is your Mothers' brother.
Worth checking the Service Manual if yr unsure how to do particular things.
That's how I do it. YMMV.
