Want to know which carb to choose? Having problems setting up the jetting details on your scooter? Wheter you are using a standard or tuned carb, ask your question here.
I have fitted one from a FZ600 (I think) and it has a friction pivot, so you can adjust it so it stays on once you have taken your thumb off the lever.
If you fit it to the gear change side of the headset, the word CHOKE is the correct way up.
