i have an 06 z400. which would be the better big bore kit...the wiseco 440, or the athena 435? and with the athena could i still run pump gas? (it has 12.3:1 compression). and with this big bore kit would it be worth it to purchase a set of hot cam's intake and exhaust camshafts too? thanks for your help.

 

I think i'd go with the Athena kit. A lot of ppl seem to have them without problems...thats not to say that ppl with the wisco does. And ya , if i was gunna get a big bore kit i'd definatly get both hotcams, DRZe valve springs, kibblewhite valves, FCR carb, hotcam shim kit

thats about $1400 in parts lol, but your bike will be running over ALOT of 450's [img]i/expressions/face-icon-small-happy.gif[/img]

what do you have for mods now?? i hope atleast an full exhaust

 

so far for performance mods i only have a white bros e2 slip on, k&n filter, and its jetted. im thinking by buying a header from white bros and the bore kit should do me well, but i still want to run pump gas.

 

are you sure you can buy just a header?? id go athena, thats what i was going to do last year but bought a banshee insead. save your money up and do it right . if your going to open the motor up you should do it all at 1 timw. porting will help out alot to !!!
