Jetting recommandation

[MaTT400KfX]

First post here, but i read a lot and learn a lot :)

My KFX is stock except for the NOSS Machine proflow kit with the uni foam filter and i would like to remove the snorkel and the airbox lid and put an outerwear on the lid. Not really sure about my altitude but on my gps i get 90 feet, is that it???
And i run the stock exhaust, anyone could tell me what jet size i should start with? and would i have to change needle and pilot or only the main jet would be good?

let me know, thanks:rolleyes:

get a stage three jet kit from alba that gives you a adj needle a 25 pilot which is one size up and a 155 mj which i ran up here in maine about the same elevation as you also go to your dealer and pick up a 160 and a 162 ,165 mj for cold weather that 155 i had in mine was a tad lean but man did it run good
