How to set up 2010 yz450f athena 500 big bore

I'm looking at installing a athena 500 big bore on my 2010 yz450f. I am wondering what i would need to adjust the fuel and settings. can I use gytr power tuner to adjust this and if so what would the settings best suited for this set up. I currently have the power tuner and was hoping i can make the adjustments needed with this unit. I am into light track riding, ice racing and sand dune riding. Looking for power gain more then anything.


Thanks Jamie.

hey, did you ever end up installing the Athena 102 bore kit? I'm looking to replace a worn cylinder and want some feedback on what power the 102mm bore makes.
