I have a post started in the jetting section already, but thought I'd try here too.... I'm going with a Athena 480 big bore kit.... From my searches and such, it appears you jet leaner for the big bore. kit is not delivered yet, so I do not know if the instructions get into jetting or not. Anyone have any experience with this? How much leaner in general, and is it leaner throughout, or just the main, or just the needle? Thanks for any help!
