what do i need to get my z-400 ready to race.

 

Trade it in for a Cannondale or Predator. [img]i/expressions/face-icon-small-wink.gif[/img]

Just kidding. But, I would do at least the following if you're serious about racing:

Pipe (take you're pick, they're all just as good, and also not totally necessary if you gut the stocker)
Noss air filter flange and filter (K&N or Uni, you're choice... I prefer Uni)
Remove snorkle baffle and/or open up remove the lid
Proper jetting (I've posted many times here and on zee400central.com (minus the ee) what I feel is optimum for lid/no-lid)
Hotcams
Dyna or Vortex Ignition

Also, you may want to look at extended a-arms, new front shocks, new tires, wider axle, new Honda-type swingarm, gusset the frame.

Big bore is up to you... I'm sure with these mods you'll do just fine in the power department.

BTW, what a crock. zee400central (without the ee) is a "forbidden" word on this forum. Gimme a break. So then you follow the instructions, go back to edit your message, and it won't let you submit it again. Nice programming... and nice "sharing" attitude with other boards.

You should not need a swing arm yet, I dont have any problems with the stock one.
Might have to ride the tank a little though.
