has anyone got this Big Papa 450 kit for there Z yet? If so does it kick butt. I am looking at getting a new Z400 soon. Just wondering how much this kit helps, for a I have friend with a modified Rappy.

 

No Big Papas yet but Trinity Racing has my motor apart with a big bore 440 kit on the way. I hope Yosh gets their kit out so I can compare. The bad thing about the 450 kit is it is illegal for there is a 440 maximum displacement. You get caught and you will be disqualified! I will keep you posted on how it goes.

 

Suzuki NZ go the big bore route on there DR-Z competition bikes, apparently irons out the peaky power delivery of the Yoshi cams etc when used with the stock bore. The 450 seems an expensive option.........
