have you checked out the database on the central yet? if not check out z400central.com and you will be able to find anything you want about your bike. i have the hmf s/o with a k&n and a 155 main jet with a 25 pilot jet about 2 3/4 out on the screw with an ehs lid for the box. check what brand the 245 they sent you is because they are not all the same size. a 145 mikuni is a 155 dynojet.
