thank you.. thats great stuff....anyone else

 

PRM skid
full exhaust
K&N w/ alba adapter
dynojet
13 t sprocket

 

All good stuff. Enjoy you're new Z!!

 

thanks ...anyone else have different options

 

Peformance wise: (last two are a little more costly but would get you in the mid 40's hp wise)
(1) Air Filter/Adapter or Airbox w/ Jet Kit
(2) Slip-on or Full Exhaust
(3) Intake Cam or Cam package of Intake/Exhaust
(4) Ported Head
(5) CDI Box

Suspension:
(1) Skids PRM's are good, I have no compalints with AC's either
(2) Upgrade tie-rods before something goes wrong
(3) Holeshot or Razr Tires out back.
(4) Upgrade handlebars to something more comfortable. Tag T2's, X-bars, Renthals.
(5) Upgraded shock/springs out front at least

There's always the little stuff to do in between big mods. Like:
Radiator Scoops
Engine Ice Cooler
Good 4 stroke synthetic oil
Gap the plug slightly larger
Parking brake block off

 

Cheap Route
1) Ditch Air box lid, snorkel ($0)
2) Pro Flow kit ( $100)
3) Jet Changes ($5)
4) Sproket Changes ($15-$50) I geared down 1 tooth on front for the dunes.
5) Ditch parking brake ($50)
Not Cheap Route
1) All above
2) Exhaust system ( I love my LRD) ($450)
3) New Rear Axle ($300)
4) FCR 39mm carb (or 41mm if you want alot of top end power) ($400)
5) Port/Polish Head ($200ish)
Good Luck
