Can anyone help me out with tuning my carb with JD kit, and YZ airbox. I have stock exhaust with Quiet is cool insert instead of the stock insert. It doesnt seem to start first kick like it used too. Also, it has a bog down low, where it never had with the WR airbox. Any help would be much appreciated. It seemd to run perfect before the YZ airbox conversion. I live in New England at sea level. Thanks!
