As if the YFZ450 isn't fast enough us Knuckle heads at Mods3 have
released another crazy power package, so be careful!  This package is
for expert racers and duners that need some serious power.

The
K&N air filters for ATVs have the
highest flow in the industry giving you more power. They are also reusable
and way easier to clean then foam filters. More power, longer lasting.
Sounds good to us.

The Outerwears is a sock that goes
over the air filter made of a fine mesh material that repels water and other
fine dusts and debris. This outerwear will also allow you to run open air
box applications giving your ATV huge power gains in stage 2 and 3.

The Fuel Filter is not a power
upgrade but a precaution to long lasting engine life. This little sucker
will filter out any dirt or grime that may have passed through your gas
tank. Better safe then sorry.

Parking Block Off Plate are used to
remove the stock bulky crap that is stuck to your rear brake caliper. That
thing restricts your quad a bit and you'll definitely notice how much easier
it rolls after you install this cool little device. Every little bit helps.

Front Rocket Sprockets are easy to
install and can quickly curve your ATVs power in the direction you want it.
If you're looking for quicker acceleration you'll want to lower the amount
of teeth in your front sprocket. If you are looking for more top speed you
will want to add teeth to the front sprocket. These sprockets are usually
held on with 2 bolts and a sliding mechanism that locks it in. Pretty easy
to install and you'll need to adjust your chain to compensate for the larger
or smaller sprocket.

LRD Pro4R Racing Exhaust. New from
LRD in 2005 is the “Pro4-R Racing Edition” line of performance exhaust
systems for popular sport ATV’s. LRD Pro4 R exhaust systems are designed to

Teather Pro Kill Switch wraps to your
wrist and to your handlebars / engine stop button in order to prevent your
quad from running if you happen to bust your ass.  Keep the rubber side
down fellas!  This kill switch is required for most races.

Magnum High Performance Clutch Kit is
needed to handle the extra power that your ATV is about to deliver. 
You can try to run the stock clutch kit for a little while but it's bound
for disaster.  Magnum Clutches are designed for high performance motors
and they bight really hard.

Intake & Exhaust Hot Cams aggressive
design are specifically for motor cross and desert racing applications. 
These big lobed cams will have your power coming on hard and low so hold on.

the CDI box will allow you to rev higher and stronger.
