2003 Suzuki z400 - Big Bore

[jeeptuff]

So I have been thinking about a big bore kit for the 03 Z400. Anybody have preference on which kit? Athena 430? At that time I will do a set of hot cams too along with more carb work.

im not much on suzuki but if it was a honda 400ex i would go with a 416 big bore because it runs just like the 440 kit except cheaper and also the bike doesnt run as hot so if their is any kit like that for the z400 i would go for it!
