The 440 kit will get you there, but that is quite pricey.

The 415 or 416 kit is a bore in kit, then throw some XR cams in, or opt for a sparks cam. The bore in kit revs alot quicker and is more reliable.

do the air box mod and and get the degree key for now. I like the clear airbox lid from powroll.

Pick a all around cam for your stock motor, see how you like that. If your a duner a top end cam would be better.

The list is realy endless for the EX
