Jetting help * Pic*

[jkosakowski]

I need help jetting my 450r its all stock with motoworks slip on and air box lid on and foam moose filter. Im thinking of a 160 main but I don't know about the pilot jet. And when I hit the throttle it sortave bogs quick, I read if I get a 55 leak jet that will help? Just wondering what you guys think I should do. Thanks

Plug looks ok, but you really cant tell too much with them really.

Id say a 55 leak should cure the bog or spring for the boyesen quickshot ($100) adjustable leak jet.
