another jetting question

[doozer]

hows it going guys, i got an '04 honda 450r w/a full yoshimura titanium exhaust, hotcam stage 2 cam, and just put a k&n filter on with an outerwear. i was just wondering if someone had close to the same mods as i do to give me a rough idea of what size jet is gonna be close to the one i need. any help would be appreciated. thanks cya later.

Most important info??? Are you run with or without the air box lid this makes a huge difference in jetting on the 450r

[doozer]

i am running with the air box lid on, and the jetting is completely stock right now.

I would run a 50 pilot and start around 150 main jet
