[QUOTE="Pete Payne, post: 1275852, member: 20445"] Yeah , I installed an athena 490 kit on a customers 450 , It was an 05 . Did the before and after. It only gave it like 1 hp . I will see if I can dig up the dyno . I seem to have way better results with a high comp piston and a web camshaft . [/QUOTE]
