DuneGuide.com is in the process of building
a KFX450R up for dune use (more details). Our
KFX 450R will
appear in Product Reviews, Magazine
articles and be part of many events at dunes throughout the United States. Stay
tuned as we research and select the products that will be used.
In stock form, the KFX450R seemed to have a slight edge over a
Honda 450R. It will be interesting to see how the KFX450R reacts after it is
uncorked. The big difference with the KFX450R is EFI. The EFI system will
adjust for altitude and temperature changes, but cannot make adjustments for new
pipes or changes in intake. The EFI must be told to give the bike more fuel with
a "map". Think of it as rejetting with a computer. Most of the
pipe manufacturers will have maps for their pipes and different airbox
scenarios.

Repacking your silencer is important
Loud doesn't equal fast
Many of the exhaust systems built for four
strokes use packing material to reduce noise output. The packing material does
not last forever, and must be replaced.
Repacking your silencer regularly is
important to maintain power and reduce unwanted noise. Don't think that louder
is better for power. Too much air past the holes in the core of the silencer
will make your performance suffer.
