Step 1: Set the Bottoming Control This is the most important step and needs to be done first. Ideally, with the rear wheel off the ground take a measurement from the axle straight up to a fixed point on the fender (assuming the fender is mounted on the frame and not the swingarm). Then, with the motorcycle back on the ground and the rider on it, pressurize the “Bottoming Control” chamber until you get the same measurement —less 1 ¼ to 1 ½”. For example, if your first measurement was 10.0″ inches then your ending measurement should be between 8.50″ and 8.75″ inches. The difference between the two measurements is referred to as “sag”, and it should equal approximately one third of your total wheel travel (see figure 3). Another method of achieving the proper sag is it start with the bike on the ground — with no rider or load on it. Pressurize the “Bottoming Control” chamber to the highest pressure you can without exceeding 150 psi. At this point the rear wheel should be “topped out” and you need to measure from the axle straight up to a fixed point on the fender as described above. Take the same measurement with rider(s) on the bike — ready to ride. The second measurement should be 1¼” to 1½ ” less than the first. If it isn’t, then bleed off the pressure in the “Bottoming Control” chamber until the proper sag is achieved. If you intend to ride the bike at this “full height” then make sure you still put about 10 psi into the “Ride Height” chamber anyway. This helps the piston that separates the two chambers to move more freely producing a smoother ride. Step 2: Set the Ride Height After you have set the “Bottoming Control” you can now adjust the “Ride Height” chamber. This is a much simpler and less crucial adjustment to make. Simply pressurize the “Ride Height” chamber until the bike is lowered to the desired height. To raise the ride height back up, release pressure in the “Ride Height” chamber. Remember, the pressure in this chamber “holds” the bike down—the more pressure the lower it goes. Though the bike may feel “stiffer” the lower you go, do NOT re-adjust the “Bottoming Control” chamber. Essentially what’s happening here is as you’ve reduced your wheel travel, you’ve proportionally increased the forces that keep you from bottoming out with what wheel travel you have left. If you do need to re-adjust the “Bottoming Control” due the addition (or subtraction) of a passenger or extra load, release the pressure from the “Ride Height” chamber first, then repeat step 1.

High-pressure fluid flow The engine rotates the pump swash plate, which has a gear mechanism. The rotating swash plate pushes the pump pistons to increase the pressure on the hydraulic fluid and feed it to the high-pressure annular chamber. The high- pressure fluid is then fed to the oil motor piston chamber where it pushes the pistons forward, which then push the motor swash plate. Power Fluid flow from pump to motor Fluid flow from motor to pump Low-pressure fluid flow The lower-pressure hydraulic fluid returns to the pump through the low-pressure annular chamber. In this way, the fluid circulates between the pump and the motor. Movement of distributor valves and pistons The distributor valves play an important role in fluid circulation. The valves are placed both in the oil pump and motor. When the pump pistons move to the compression side, the valves connect the piston chamber and the high- pressure chamber. When the pump pistons move to the expansion side, the valves allow a connection between the piston chamber and the low-pressure chamber. The valve in the oil motor moves opposite to its counterpart in the pump, ensuring the circulation of fluid within the system

The main Carburetor functions are: • To form a proper homogeneous inflammable mixture of fuel and air • To supply the engine with varying amounts of this mixture The fuel-air mixture is formed through vapourising and by uniformly spraying fuel into the airstream or at least by atomising it into very small droplets. Atomization takes place in this way: liquid fuel from the atomiser nozzle meets the flow of air which carries it, broken into very fine droplets, to the combustion chamber. We have spoken of a “proper” mixture because the mixture strength, defined as the amount of air in weight mixed with a fuel unit of weight, must have a precise value, ie it must be within the limits of inflammability so that the mixture can be easily ignited by the spark in the combustion chamber. lnflammmability limits for commercial petrol are: 7: 1 (rich limit ie. 7 kgs of air and 1 kg of petrol) , down to 20: 1 (lean limit ie. 20 kgs of air and 1 kg of petrol) . To obtain optimum combustion between these inflammability limits, a value very close to the so- called stoiciometric value is needed ie. about 14.5 – 15.0 kgs of air to 1 kg of petrol. A stoiciometric mixture ratio is one which ensures complete combustion of fuel with only the formation of water and carbon dioxide. The stoiciometric mixture ratio depends on the kind of fuel used, so if the fuel is changed, this fuel- air ratio will also change (see SECTION 5.1 ) .

1. The Float The float bowl acts as a fuel reservoir to meet engine demand. The float is hinged on a pin in the float boss. It rises and falls with the fuel level in the float bowl. The small metal tang integrated in the plastic float supports the float valve, also known as the float needle. As the fuel in the float bowl rises, the float valve is pushed into the valve seat, until it’s high enough to shut off the fuel flow to the bowl. As fuel is used the level in the bowl drops lowering the float which pulls the float valve from its seat, and fills again. Adjusting the height of the float has a big effect on the mixture as a low or high float level makes it harder or easier for the vacuum to suck fuel into the venturi. Differing float levels cause an imbalance which may be perceived as vibration. 2. The Choke This system is referred to as the choke. But that’s a misnomer. When you pull the choke knob, what you’re doing is retracting a plunger that opens a tube connected to the starter jet, allowing additional fuel to enter the venturi just below the vacuum hose nipple. It supplements the pilot system at start up. 3. The Pilot System The primary purpose of the pilot system is to supply the mixture at idle. It continues to supply fuel throughout the entire throttle range, but after about 1/8 throttle is reached the main system starts to put out more of the total mixture, up to full throttle. By adjusting the idle with the big screw on the left side of the carburettors the position of the butterfly is altered, so exposing one or more of the four small holes that are drilled into the venturi, (leading to the pilot jet) just under the butterfly valve, letting more or less air pass the butterfly. Adjusting the pilot screw that’s under the carburettor varies the amount of air premixing with the fuel before it enters the venturi. 4. The Main System Open the throttle and the cable that’s connected to the butterfly valve turns it from vertical to horizontal, so letting more air through the venturi. This increases the vacuum effect that is transferred up through the vacuum drilling in the slide to the diaphragm valve that leads to the diaphragm chamber. The top chamber is separated from the bottom by a rubber diaphragm. The bottom chamber is open to atmospheric pressure from the airbox. When the vacuum in the top chamber rises enough, the constant ambient pressure of the lower chamber helps the diaphragm valve overcome the downward force of the diaphragm spring, so it rises from the ven- turi. As the diaphragm is raised the needle is pulled out of the needle jet, exposing a thinner portion of the needle taper which allows more fuel to rise into the venturi to meet the increased engine demand. The key parts of the main system are shown in the photo below

REMOVING THE STOCK EXHAUST SYSTEM 1. Remove the mufflers by loosening the pinch clamps on the front of each muffler. 2. Remove the muffler mounting bolt from the right side passenger footrest, slide the mufflers off and set them aside. Note: Save the mounting bolt, it will be reused for installation. 3. Loosen the pinch clamp on both front and rear head pipes, they’re located at the resonance chamber (the black box where the pipes meet). 4. Remove the two acorn nuts that mount the head pipe to the cylinder head. Remove the two piece header flange and set it aside. 5. Remove the front head pipe by rotating it down and pull it out of the resonance chamber. 6. Remove the two acorn nuts and flange from the rear head pipe. Remove the two bolts from either side of the resonance chamber and lower rear pipe and resonance chamber down and out and set it aside. 7. Remove the rubber grommets at the resonance chamber mounting points. INSTALLING YOUR NEW VANCE & HINES EXHAUST SYSTEM 1. Install the new mounting bracket (stamped 317) to the inside of the stock muffler mounting point (Refer to FIG. 1). 2. Unscrew all of the hose clamps (supplied) until they are completely loose. Mark the top edge of all three heat shields with the location of the mounting clips that are welded to the backside. Position the front heat shield over the head pipe and feed the tail end of the hose clamps into the clips. Be sure that each hose clamp is engaged with both clips. Repeat this step with the rear and collector heat shields. To facilitate the installation of the collector heat shield use a forward sliding motion from the rear of the collector. Do not force the collector heat shield directly onto the collector as damage to the heat shield will result. Note: the collector heat shield uses the 3/8″ wide clamps. 3. Rotate the hose clamps in the shields so that the screw drives are accessible. Tighten only finger tight at this time. Note: The screw end of the hose clamp should be accessible, but not visible when pipe is mounted on the bike. 4. Check to be sure that the stock exhaust gaskets are in good shape. If you have any doubts as to their condition, replace them. 5. Install the header with the heat shields attached, to the front and rear cylinders using the stock nuts and bolts. Leave them loose at this time. 6. Slide the chrome muffler clamp (supplied) onto the inlet end of the megaphone. Install the 5/16″ x 1 1/4″ bolt with a flat washer on either side of the clamp followed by the 5/16″ lock nut (hardware supplied). Leave the clamp loose at this time. 7. Slip the megaphone onto the head pipe collector, engaging the collector heat shield between the clamp and the outer slip joint tube. Slide one dog bone shaped nut plate under the bracket that

Throttle Body Assembly (TBA) — The throttle body assembly (also called air valve), controls the airflow to the engine through one, two or four butterfly valves and provides valve position feedback via the throttle position sensor. Rotating the throttle lever to open or close the passage into the intake manifold controls the airflow to the engine. The accelerator pedal controls the throttle lever position. Other functions of the throttle body are idle bypass air control via the idle air control valve, coolant heat for avoiding icing conditions, vacuum signals for the ancillaries and the sensors. FUEL INJECTOR — There are basically three approaches in delivering the fuel to the engine: • Above the throttle plate as in throttle body injection • In the intake port toward the intake valves as in multi-port injection or central multi-port injection. • Directly into the combustion chamber as in gasoline direct injection systems (GDI). The fuel injector is continuously supplied with pressurized fuel from the electric fuel pump. The pressure across the metering orifice of the injector is maintained constant by the fuel pressure regulator. The fuel injector is an electromagnetic valve that when driven by the ECU delivers a metered quantity of fuel into the intake manifold (or combustion chamber in the GDI system). The ECU controls the fuel flow by pulse width modulation. The time the injector is driven into an open condition is determined by the following sensor inputs: • Engine RPM • Throttle position (TPS) • Manifold absolute pressure or mass air flow • Engine coolant temperature • Oxygen sensor feedback voltage • Intake air charge temperature • Battery voltage CENTRAL POINT INJECTION SYSTEM (CPI) — Electronic fuel Injection system consisting on a single fuel injector mounted in the throttle body. DIGITAL FUEL INJECTION (DEFI OR DFI) — Electronic fuel injection system controlled by digital microprocessors as opposed to earlier systems that were of analog design. The analog input signals to the microprocessor are converted from analog to digital before being processed.

Intake system Fresh air is drawn into the filter box through the intake snorkel 1 , past the carburetors 2 and through the air filter 3 . The cleaned air is conducted to the combustion chamber through the carburetors and intake ports. 1 2 2 3 2-4 Repair manual KTM LC8 Art.-Nr . 3.206.016-E Secondary air system The secondary air system supplies fresh air to the emissions in the exhaust port, resulting in the afterburning (oxidation) of the emissions. A line leads from the filter box 1 to the control valve 2 which opens as soon as the throttle valves 3 are opened. The line continues to the reed valves 4 in the cylinder heads which are actuated by the pressure pulsation in the exhaust system. As a result, cleansed fresh air arrives in the exhaust port. The oxygen content in the air and the high exhaust gas temperature cause the emissions to oxidize. If the throttle valves are closed and the engine goes into an overrun condition, the underpressure in the intake port will rise and the control valve will close. This prevents exhaust backfire (combustion of the unburned fuel/air mixture). 1 2 3 3 4 4 4 2-5 Closed thermostat The thermostat is closed if the temperature of the cooling liquid drops below 75°C.

The water pump 1 pumps the cooling liquid through the cylinder and cylinder heads 2 , the aluminum cooler 4 and the thermostat. The pressure in the cooling system (max. 1.4 bar) is regulated by a valve in the radiator cap 5 . The cooling liquid level in the compensating tank 6 must be between the MIN and MAX marks when the engine is cold. The fan 7 switches on at 102°C.

Installation: 1. Remove the fork springs according to the OEM Owner’s Manual. 2. Check/adjust fork oil level and weight according to OEM Specifications. Caution: Most inverted forks will not require the use of any shim washers or spacers. In cases where use is necessary with the twin chamber style fork, the shims must be placed at the bottom of the spring. Most conventional forks (non-inverted) will use shim washers or spacers at the top of the fork spring. 3. Install Factory Connection fork springs and refer to OEM Owner’s Manual for proper assembly procedures. 4. Be sure to double check all fasteners. Note: Most modern day forks require special tools for disassembly and assembly of the components. Examples : Showa 47/49mm Twin Chamber, KYB 48mm Twin Chamber, WP 07 SX Models/SXS Components. Installing fork springs is an intricate process that should be performed with extreme care by a qualified suspension technician. Failure to install the springs correctly could cause damage to one or more components of the fork. This damage, although not readily apparent, could lead to unexpected failure or rider injury. Factory Connection manufactures models specific fork springs. Installation of a Factory Connection spring not designed for your motorcycle may result in unexpected failure and rider injury. Please consult your Factory Connection spring dealer or call Factory Connection directly if you are unsure about a spring/or springs. 1. Factory Connection’s Limited Lifetime Warranty Factory Connection warrants, to the original retail purchaser (“consumer”) who retains ownership of the vehicle on which the suspension spring(s) (“products(s)”) was originally installed, all suspension springs for life against factory defects in material and workmanship (other than defects in finish) when used under normal use and operating conditions. 2. Your Remedy Upon verification of warranty coverage, Factory Connection at its option will replace defective or prematurely worn-out product (s), without charge, or refund the purchase price of the products(s). This is the Consumer’s sole and exclusive remedy for any loss or damage, however arising, due to a nonconformity or defect in the product(s). 3.
