Yamaha YFZ450 Velocity Intake System. All Fuel Injected models only. YFZ450R and YFZ450X all years.
Kit Includes: Aluminum Intake, K&N Filter, Outerwears Pre-Filter. Rubber Snorkel and all hardware.
This race designed intake makes big 5-15% power gains over the stock airbox!!! The factory intake tube is too small and not smooth bent, it restricts the intake flow and causes turbulence with the intake charge before reaching the throttle body.
Replaces your factory airbox with a mandrel bent and ultra-light aluminum intake tube. Intended for use in dry riding conditions. Increases intake velocity for max power at high RPM's with a noticeable increase in bottom end torque. The stock airbox can impair airflow at high RPM while at low RPM the stock intake snorkel can collapse when you jump on the throttle. For that reason this intake really kicks up the throttle response and power at low-mid RPM.
Comes with K&N performance filter RU-0640. & Water Repellent Outerwears 20-1090-01. This race intake is intended for dry riding conditions, and shaves off 2.6 lbs.
This intake with filter and hardware is only 1.2 lbs vs stock 3.8 lbs. Intake tube starts with a mandrel bent 6061 T6 aluminum tubing; a welded bracket bolts to the left cross bracket mounting pad. The air inlet temp sensor mounts in stock fashion to the top of the new aluminum intake via a welded bracket.
Includes a bracket that will mount your stock crankcase vent box (attached at the side of airbox in stock form) use with optional K&N crankcase breather 62-1330. No additional fabrication necessary, this is a simple bolt on unit!! Aluminum Intake (2.6 lbs lighter than stock airbox). Hardware and all mounting provisions. Dobeck Performance EJK Gen 3.5 Fuel Injection Controller 8310048.Yamaha YFZ450R EFI all model years. NO COMPUTER NEEDED NO DYNO REQUIRED Plug N' Play Installation Minutes to Install, Base Settings are Preset Uses Unique Load Based Technology Offers Full Range Tunability Does Not Interfere with Stock ECU Operation Simple Push Button Adjustment Interface Water-Resistant CARB Approved E. The controller comes with three interactive buttons that are used to enter the adjusting mode and change the on-board tuning features' light settings. When power is applied to the unit, the adjusting mode may be accessed at any time by pressing the MODE button.
The adjusting mode is distinguishable by at least one or more LEDs flashing. The current adjust mode is determined by the color of the flashing LED(s) and whether or not the 8th LED is blinking blue.
The adjusting mode is exited by waiting several seconds without pressing any buttons. Upon exiting, the light setting is automatically saved for each individual mode. The light settings in each mode are adjusted by pressing the PLUS (+) and MINUS (-) buttons located on the right and left side of the mode button, respectively. For easy reference, the LEDs are numbered 1 through 8.
However, the LEDs can be adjusted to the following positions: 0.5, 1, 1.5, 2, 2.5, 3, 3.5, 4, 4.5, 5, 5.5, 6, 6.5, 7, 7.5, 8. Try the interactive Flash Demo below to get used to adjusting the modes and understanding the light setting positions. NO COMPUTER NEEDED This EFI controller is one of the only ones on the market which allows a large range of adjustability without the use of a computer. We like to use the term'on-the-fly' tuning. You can literally drive the vehicle, make setting adjustments, and instantaneously feel the results.Obviously for safety purposes we recommend you pull over to the side before making adjustments. Some after-market EFI controllers like to claim'on-the-fly' tuning which to them means toggling only between a couple preset maps. The controller actually has 11,390,625 available maps in the unit which are accessible without using a computer program to reprogram the unit. There does exist a computer program called POWERLAB and the controllers can be reprogrammed by a computer, but most users do not require this ability. Why deal with the complexity? It's an Electronic Jet Kit to make fuel injection tuning easy, simple, and fast so you can enjoy more time riding. NO DYNO REQUIRED You do not have to be a professional mechanic or tuner and have access to a dynamometer in order to tune your vehicle with the EFI controller. Knowledge and good equipment obviously are a huge plus, but you can do just as good a job and sometimes better by tuning in real world riding situations. The controller allows this by breaking down a drive cycle into very understandable zones to make adjustments. Most controllers have the basic Idle/Cruise, Acceleration, and Full Throttle zones to adjust. Every rider can understand this terminology.
The greatest advantage about tuning your vehicle yourself is your ride will be custom set up to your driving style. Plug N' Play Installation - Minutes to Install, Base Settings are Preset All of the offered controllers are plug n' play installations and can be done in a manner of minutes instead of hours. All you have to do is locate the OEM injector connections on your vehicle. Most of the time this will only require you to remove a few components to gain access to these injector connections. A number of new applications will also require you to find the O2 connections on your vehicle if present.Power for the unit is gained through the injector connections and a black ground wire just needs to be attached to the negative terminal on the battery if present or by a metal screw onto the vehicle frame. After physically installing the controller in most cases you are all set to go on a test ride. The unit comes pre-programmed for a stage 1 setup for each application. After your initial test ride you then can make some fine tune adjustments which may be required based upon your modifications. Uses Unique Load Based Technology The controller uses Load Based Technology which sets it apart from most of the competition.
Most EFI controllers use what is called'Alpha-N' Tuning Technology. Alpha-N tuning is associated with just using Throttle Position (TPS) and RPM as the factors to make tuning adjustments. Load Based Technology differs by using Rate, TPS and RPM as the key factors for adjustment.Load Based tuning allows a user to tune their vehicle for every gear and for all riding conditions. Load can easily be explained by stating that riding up a hill puts more "load" on the vehicle than driving on a flat road, but yet the same TPS and RPM can be achieved in both circumstances. Like carburetor jet kits of the past the controller offers a range of adjustability to tune your vehicle. Instead of physical jets and needles the controller has this adjustability built into the unit and can quickly be adjusted while riding the vehicle.
Essentially with all EFI vehicles software has replaced some hardware. The controller can be installed and set to actually allow the user to still run a stock configuration, but allows the user to ADD or PULL fuel within easy to understand tuning zones.Does Not Interfere with Stock ECU Operation This is a very common feature of all after market EFI controllers, but needs to be stated to reassure all end users. The controller does not trip any engine codes or affect the ECU operation in any way. Simple Push Button Adjustment Interface The controller offers'on-the-fly' adjustment using three push buttons on the label interface.
The three buttons are labeled MODE, PLUS, and MINUS. With power supplied to the box by either starting the vehicle or just turning the key on, the adjustment modes are accessed by pressing the MODE button. Light setting changes are then made for each respective mode by pressing the PLUS and MINUS buttons.No extra tools are required to make tuning adjustments. Water-Resistant The hardware components within the controller are covered with a substance to make the controller water-resistant. The controller is still an electrical device and without this coating would short-circuit when in contact with water based substances. The controller is NOT 100% water proof, but will continue to function properly through rainstorms, snow, washing your vehicle, etc. The item "YFZ450R EJK Fuel Controller & Velocity Intake Kit K&N air Filter YFZ450X YFZ450" is in sale since Friday, October 16, 2015.
