Cool 2005 YFZ 450 jetting help!

Hey guys, this is my first post here so don't expect the best. Also, I'm guessing there are many posts on this that i should look at so sorry if this is a repeat thread

I've got a 2005 YFZ 450 with a full FMF pipe, k&n filter and an aftermarket carb that I do not know the name of
i just bought it and now after a few rides am noticing it is running way to lean i.e sounding like a popcorn machine on decel and falls on its face on acceleration.

I need help with what jets I should run any help would be nice.

Elevation: 581 feet
