Go to your local Honda dealer. They'll tell you what one is in there now (if it's stock) and they can order a new one for you, or they should have it in stock. Your gonna have to richen your jetting, you can do this by going up a few numbers on your main jet. I'd say at least one or two sizes up would be good.
