I have an 06 Honda 400ex and i have recently ordered an fmf pc 4 and a K&N air filter. I am looking to save money and jet it myself but i am unsure which jets to buy. I live in florida at low elevations. Any suggestions on jetting would be appreciated.

To start out with is your pipe a slip-on or full? Do you want to jet with or without the lid?

When I tell people jetting specs I tend to tell them so the carb is on the rich side, just so I'm not the cause of a blown up motor. If you guys know what I mean. It's better to be rich than lean I always say.
