Best Upgrade for under $20 bucks! |
| |
With the stock 20 inch tires the gearing on the KFX400
may seem a little off. You'll notice that 2nd gear winds
out a bit fast and 3rd gear doesn't have enough bottom end
to pull you out of the turns hard. Add a
13 tooth sprocket in the front and you'll be able to
come out of the turn in 3rd gear rippen. Doug Gust uses the
13T sprocket. (you will loose a bit on the top end) |

Best exhaust for the KFX 400 |
| |
Lets go down the list of exhaust systems I've ran on my
machine. Yoshimura, CT Racing (great pipe), White Brothers,
and
Pulse Charger. I was in love with my CT pipe and Dirt
Wheels had it ranked #1 in a pipe shoot out couple years ago
for the KFX / Z 400.
Pulse Charger Sent me out a pipe and asked me to try it
out and I sold my put my CT pipe up for sale the next day.
The
Pulse Charger sounded so much deeper and it just ripped.
Due to legal issues Pulse Charger is not currently selling
pipes so Mods3 did their homework to research some new pipes
and we found some great ones. LRD makes an awesome
system as well as Yoshimura. For Racing the Pro Series
Yoshi is the way to go but for everday woods riding and
trails we love the quality and price of the LRD Pro4 full
system all available in our power
section. |

Another great upgrade for more bottom end. |
| |
The
UM Aluminum Air Box is a must on this machine to improve
your bottom end. People say who cares if its aluminum,
what's the difference. The difference is that the Air box
is bigger and the opening is way larger to allow more air
in. This boxes uses an oversized
250R K&N air filter. The
mesh screen that goes over top is sold separately. |

UPDATED POWER KITS!!!
My Name is Ryan and I head the web development Department and ride a
KFX400. This photo above is my quad. I've ran several different set
ups on this quad thanks to all the prototypes that come across my way.
I hope to provide my fella KFX400 Riders with some decent info and don't
sell out and get a 450 unless it's a Green. |
