This nitrous manifold greatly simplifies the way extra fuel is delivered that is needed for nitrous use. The carburetor vents
are connected to this manifold, allowing the carburetor(s) to breathe normally through the airbox when nitrous is not used.
When nitrous is sprayed, the manifold produces a positive pressure that goes to the carburetor float bowl, which “pushes”
more fuel through the main jet of the carburetor(s). This eliminates the need for an extra fuel pump, fuel solenoid, extra
plumbing, and nozzle(s) that are necessary to inject the extra fuel in other systems.This manifold is also designed to vary the float bowl pressure in relation to nitrous pressure, thus keeping the nitrous and fuel delivery in sync. Fluctuations in bottle temperature greatly affect nitrous pressure, which affects nitrous delivery. By automatically adjusting the fuel delivery as nitrous pressure varies, this manifold makes nitrous safe, reliable, and easy to use. The valve shown in picture (A) will require both the 4an x 1/8 npt fitting and the 1/8 npt plug. The valve shown in picture (B) will only need the 4an x 1/8 npt fitting. Use thread sealant on these fittings, be sure not to get any sealant inside the valve. Remove the upper mounting bolts on the front bumper. Install bracket support strap and reinstall the mounting bolts. 2. Install rear strap mounts over frame tubes. 3. Attach saddle bracket to support brackets, front and rear using supplied hardware.

Relationship Between Tire Characteristics and Vehicle Pulling to One Side When radial tires are rotating, they have the characteristic of generating force in the lateral direction between the tire and the road surface. This lateral force is comprised of two factors: S Ply-steer, which changes direction according to the rotation direction of the tires.
S Conicity, which is generated in a fixed direction regardless of the tire rotation direction. If these lateral forces are too strong, vehicle pulling will occur. A. Ply-Steer Lateral force due to ply-steer is produced by the construction of the belts inside the tire tread. With radial tires, the wire of the belt is slanted as shown in the illustration below. Thus, it is in the lateral direction that tire tread easily changes shape (stretches), and lateral force is generated between the tire and the road surface in the lateral direction.

Kawasaki KX250F Factory Tuning And Fuel Injection to keep expert riders at the front of the pack

Battery-less fuel injection system Designed specifically for motocrossers, the fuel injection system incorporates a small lightweight ECU and operates without a battery to further eliminate unnecessary weight. And of course, fuel injection eliminates the need to adjust engine settings to suit track and climate conditions. Ensuring quick starting without a battery was a prime directive when developing this fuel injection system. Using only electricity generated by the kick starter, the engine can be started with only three rotations of the crankshaft. The system delivers electricity in the following order:1) ECU, 2) fuel pump, 3) injector. With a warm engine, starting can be accomplished in a single kick. The compact, lightweight ECU, located just in front of the steering head (behind the number plate), was designed specifically for motocross use. To help cope with the shocks and vibrations of motocross riding, the fuel pump relay is built into the ECU. A 43 mm throttle body makes use of a progressive throttle link to deliver airflow in much the same way as would a FCR carburettor. Using two linked shafts, the throttle body opens more quickly after the 3/8 open position, delivering sharp response and excellent power. Lightweight throttle body is approximately half the weight of a FCR carburettor – a weight savings of about 600 g. To ensure the high-rpm engine’s demand for a high flow of fuel in a short period is met, the KX250F’s injector features larger holes than that used on the KX450F. A fine atomising injector with 4 holes disperses spray particles with a droplet size of 120 µm. Fuel flow is about 20% greater than on the KX450F. The newly designed fuel pump, located in the fuel tank, is a lightweight aluminium construction. (Fuel tank capacity is now 7.2 litres.)

1. Remove seat and disconnect battery. Remove fuel tank along with both left and right side battery covers, and remove air box from carburetor (all per Yamaha standard shop manual procedures). 2. Remove chrome plastic cover over fuel pump and disconnect choke cable/knob from lower pump bracket. Remove pump-to-carb fuel line from fuel pump. Disconnect fuel pumps electrical lead connector. 3. Remove two (2) hex-head pump mounting bracket bolts and remove pump assembly from motorcycle. Slide fuel pump up and off bracket mounting posts (Caution: excess fuel may drain from pump and/or fuel lines and fuel filter!). Remove heat shield. Remove remaining fuel line from pump. Pull all fuel lines from filter and remove steel springs and hose clamps from these lines (these will be reused on the kits fuel lines). With a sharp knife or box cutter, trim off the top portion of the fuel pumps rubber isolation/mount system per Photo A. Next cut pumps wiring harness approximately half way between connector and pump. Strip the insulation from the ends of these wires as well as from the supplied Baron harness extension wires. Using the supplied electrical butt connectors, crimp Baron harness extensions red wire to pumps black-w/blue-strip wire, and Baron harness extensions black wire to pumps black wire. Repeat this process on other side of wire harness extension with pumps connector. Now, referring to Photo B, you will need to cut off the square tube that runs along the side of the fuel pump with a hack saw. Cut down toward pump body in a straight cut, then cut tube off by cutting along the body. This will allow you to twist pump in the rubber mount so the curved spigot is facing up (clockwise approx 1/4 turn). 4. Remove pump-to-carb fuel line from carb and separate electrical wires from this line. Remove this fuel line from engine. Re-route choke cable to right side of engine (toward carb) and rotate it up and over rear cylinder head back toward left side of bike. Mount new Baron choke bracket to the choke cable and tighten plastic nut. New choke bracket will mount to rear fuel tank mounting location (Photo C). 5. 99~03 models – Remove electrical relay bracket (found under the right side cover) from the bike and slide each relay off of this bracket. Install fuel pump onto new Baron Fuel Pump Bracket and install bracket in the same location as the stock bracket you just removed, using stock mounting hardware. Refer to Photo F for proper installation. 6. 04~07 models Remove electrical relays from stock bracket and remove relays from rubber holder. Cut rubber holder per Photo E and replace one of the relays into the rubber and install on to new Baron bracket. The second relay will be placed to the right of the tool bag under the seat and secured with the provided two-sided tape pad. Reconnect plugs to the relays. (Photo F)
