Im picking up my new '03 kfx400 tonight, very excited.
Anyway, this guy had a K&N jet kit installed, but told me it had been jetted for a pipe, when all it really has is a K&N filter, outwears, and no airbox lid.
I drove it and its definitely not jetted in the right ballpark. It idles fine, but cuts hard lower-mid rpm, then takes off top end. my guess is its way rich because of the jetting for the pipe.
So what would be a good starting point for me to re-jet? please let me know basically where i have to be for fuel screw, main, needle, etc. elevation is roughly 200-600 feet
