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.
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
Mods3 sold a ton of Pulse Chargers even
though when recommended to riders they would
say, "Pulse Who." The response we got
back was overwhelming, no pipe on the market
could compete. We always do our
homework in finding the best pipe for the Z
and KFX400s but due to legal issues the
Pulse Charger is currently not available.
Mods3 had to go back to the drawing board
and find some quality pipes to sell and make
our customers happy. If you're racing,
Yoshimura Pro Series is the way to go
and was used by Doug Gust on his Z400.
If you are riding light motor cross, woods,
and just the weekend basher we've got the
LRD PRO4 exhaust. In my opinion
you can't find a better full exhaust for the
price. Great sound, great power, and
very well crafted. Check out more
pipes and power parts in our
Another great upgrade for more bottom
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
Our Take on the KFX 400
My Name is Ryan and I head the web development
Department and ride a KFX400 which is the same thing as
a Z400 but green. 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 Z400 and KFX400 Riders
with some useful info on parts and upgrades that will
help you with power and handling. We
have plenty of great Mods for your Z just
take a look around.
