its one complete unit,so you just put the front part onto the barrel studs and then lift the back up and put the two bolts into the two other holes in the crankcase dont tightn them up until you have the front exhaust nuts that go into the barrel tight then after that do the two rear ones up.i would stronly suggest removing the seat bucket to do it as its only held in with 4 nuts and the two filler caps.lift it out with the seat attached to it.
