I just purchased a nice low hours 11' KX450f but it only came with 1 EFI module (white). I checked the OEM sites at motorsports.com and rockymountainatv.com and could not find the other 2 to order? Was wondering if these EFI modules are interchangeable between years? Also where could I order from on internet? Closest Kawi dealer is like 1hr away from me. Thx in advance for help!!
