Hi Bret,
Don't wast your money on the emissions kit - It is for the US only, we don't have that junk on our Aus bikes.
As to the rectifier kit - Yep, I have it and it works a treat. You will also need to get the sump air filter kit too as you need to get rid of the stupid airbox that the rectifier sits on. That means getting rid of the air pipes that go from your sump breather through to your stock airbox.
I am sure the TPO site tells you what you need - and you do need it.
The changes get rid of useless pipes, clean up the look of the bike and don't cost much. Good mod!
Ciao, R_usty
