Am I too small for this motorcycle? Duke – Sun May 14 17:38:31 2000 I’m only about 5’2″ and don’t have a problem, even though I can only touch the ground with the ends of my toes. Once you get a feel for the balance of the bike it’s not hard to keep everything upright. Only place I have trouble is pushing the bike backwards in a parking lot. Usually I just walk the bike (beside it) to where I can get on and get going. How does the EX500 compare to the EX250? Craig M. – Mon May 22 10:23:29 2000 I have both the EX250 and the EX500; both are Y2K models. The 250 is a screamer that performs well and can easily get me into trouble. My only complaints about the 250 are the excessive nose dive when getting on the front brake hard and the skittishness of the rear during high speed cornering. Both are easily corrected with suspension adjustments, I’ve just been too lazy to get the parts and do the work. A bit more wind protection would be great too. The 500 addresses these problems, the diving of the front end (to a degree); the rear’s skittishness and the wind protection. A plus for the 500 is the greater torque and power off the line; it pulls stronger (in my opinion) and will get you into illegal speed territory just a bit quicker than the 250. With greater weight, is has more stability in high speed and windy situations. Insurance is just about the same for both, with the 250 getting the nod for gas mileage. Service requirements are almost identical for both as well, being that they’re both parallel twins, the technology is the virtually the same. The downfalls of the 500: $2K more than the 250 (can do a lot to the 250 with that kind of money); buzzy mirrors, barely useful; heavier weight to have to push around the garage; lesser gas mileage (55-60 MPG; 250 pushes 70 MPG easily); engine is worse than a nervous dog shaking around at idle and at speed (here the 250 is far superior and much smoother). In my opinion, the 500 is a better suited for a larger rider, from a comfort standpoint. I feel I can stretch out a bit more on it than the 250 (I’m 5′ 9″, 160 lbs). The 250′s brakes are better tuned than the 500 and the shifter is much smoother. That may be due to the 3,500 mile difference between the two bikes. Bottom line, both bikes are great, the 250 is now my wife’s ride (mainly) and the 500′s mine (unless she steals the keys away). In time, I’ll make the adjustments to the 250; she doesn’t push it like I do.

1. Get a degree in Mechanical and Electrical Engineering. (Just kidding!) 2. Remove the seat, side panels, and gas tank. If you are color blind or even think you might be a little color blind, now is the time to get someone to assist you. Successful installation of the kit requires good color recognition. You want to go riding this weekend, don’t you? Photo 1 3. Unplug the yellow, blue and black taillight wires from the stock wiring harness (Photo 1). 4. Unplug the headlight from the stock wiring harness and remove. 3 Photo 2 5. Remove the headlight on/off switch. Unplug the red two pin connector with yellow and brown wires (Photo 2) from its mate that was under the fuel tank. 6. Clip the zip tie holding the headlight leads to the fork tube, coil it up and secure it to the frame in front of the voltage regulator as shown in Photos 3 and 4. Remove bracket shown in Photo 3. 4 Headlight Leads Remove this bracket Photo 3 Coil up wires and secure with a zip tie Photo 4 7. Rear Turn Signal Installation: Turn signal mounting requires that you drill a 3/8 inch hole in either side of the rear fender near where it meets the side panels. You can achieve a clean, durable installation using this mounting location. Mount the rear turn signals by drilling a 3/8 hole in the rear fender in the location shown in Photo 5 and Photo 6. Use the templates provided at the back of this instruction manual to determine the hole locations. Note that you will also be drilling a 3/16 hole on each side as well. You may find it easier to remove the fender to drill and attach the turn signals rather than performing this modification while the fender is on the bike

PREP AND TUNING FOR POWER: 1. Specific applications may show an increase in performance through additional carburetor tuning. 2. Aftermarket distributor curve kits and aftermarket ignitions may be used with the Street Tunnel Ram intake manifold. 3. Use modified or high performance cylinder heads such as our Performer RPM, and port match the intake manifold to the heads. 3. The engine’s compression ratio should be at least 9.5:1 to work properly with Torker-Plus or Performer RPM camshafts. INSTALLATION PROCEDURE INTAKE MANIFOLD BASE 1. Use only recommended intake gaskets set when installing this intake manifold. 2. Fully clean the cylinder head intake flanges and the engine block end seal surfaces. 3. Apply Edelbrock Gasgacinch sealant P/N 9300 to both cylinder head flanges and to the cylinder head side of the gaskets, allow to air dry, and attach the intake gaskets. 4. Do not use cork or rubber end seals. Use RTV silicone sealer instead. Apply a ¼” high bead across each block end seal surface, overlapping the intake gasket at the four corners. This method will eliminate end seal slippage. 5. Install the intake manifold hold-down bolts (We offer an Intake Manifold Bolt Kit #8504 that includes small-head silver Cadmium-plated bolts and matching hardened washers). Apply a small amount of RTV silicone to the threads of the eight inner bolts (1,2,3,4,5,7,9, & 11) (See Figure 1) . This will prevent oil weepage, as generally these are not blind holes in the cylinder head. 6. Torque all of the manifold bolts in two steps by the sequence shown in Figure 1 to 25 ft/lbs. INTAKE MANIFOLD TOP 1. Apply Edelbrock Gasgacinch sealant P/N 9300 to the gasket mating surface and install the gasket and manifold top. 2. Install and tighten the supplied hold down bolts using a liquid thread-locking compound on the bolt threads. As an extra safety precaution, we suggest you drill a small safety wire hole in the head of each bolt and safety wire them together. Edelbrock Corporation expressly disclaims any liability for any and all consequential damages

1. Disconnect the battery ground wire from the battery. 2. Turn the fuel petcock to the “OFF” position. 3. Elevate the rear of the fuel tank for better access to the carburetor area. 4. Remove the coil, horn or other devices on the left hand side of the engine to allow free access to the intake manifold bolts. 5. Remove the complete air cleaner assembly, including the backing plate. 6. Disconnect any vacuum hoses and the fuel hose from the stock carburetor. 7. Disconnect the choke cable from the frame. 8. Remove the stock carburetor. 9. Evo: remove the stock manifold. 10. Twin Cam: unplug MAP sensor, remove manifold and then remove the MAP sensor from the manifold. Installation: Intake Manifold: Twin Cam only: Install MAP sensor in Mikuni manifold. 1. Attach the Mikuni manifold to the engine. Align the manifold before tightening the bolts. The flange surface of the Mikuni manifold should be parallel with the front of the engine’s cam cover. Use a level or angle meter to check this. Tighten the manifold bolts. 2. Attach the rubber flange to the Mikuni manifold with the 5/16″x3/4″ bolts and washers. To ease installation, use liqiud detergent to lubricate the manifold seals. Choke: Evo: We recommend that you use the Mikuni choke cable that is furnished with the carburetor. However, you can use the stock Harley cable (’90-’99 models only) if you follow the Twin Cam choke cable instructions. Twin Cam: 1. Remove the Harley choke cable from the stock carb. 2. Remove the Harley spring and plunger from the Harley choke cable. 3. Remove the Mikuni spring and plunger from the Mikuni carburetor. 5. Install the Mikuni spring and plunger onto the Harley choke cable. Change nothing else; be sure to use the Harley plastic nut, not the Mikuni nut. 6. Install the new assembly into the Mikuni. Be careful to only gently tighten the plastic nut.

During more than 25 years as one of the world’s leading manufacturers of advanced motocross machinery Yamaha has consistently developed and produced exciting and innovative new engine technology. Now Yamaha are about to amaze the off-road world once again with what is surely the most important new powerplant to be produced since our liquid cooled YZ 2-strokes of the early 1980s. Extremely compact and remarkably light, the YZ400F’s 4-stroke powerplant incorporates some of the most sophisticated technology ever seen on a production motocross engine. Displacing 399cc, this 55hp high performance liquid cooled motor features bore and stroke dimensions of 92 x 60.1mm – a free-revving short stroke configuration which allows this ground-breaking motorcycle to produce a wider powerband than today’s 250cc 2-strokes. Short skirt piston runs in a ceramic composite plated cylinder which reduces frictional losses, thereby enhancing throttle response throughout the rpm range. To ensure overall dimensions are kept to a minimum this revolutionary new engine is fitted with an extremely light and compact 5-valve cylinder head. Running a 12.5:1 compression ratio and with a combustion chamber volume of 20.8 cc, this high efficiency 5-valve design runs with lightweight valves, springs and lifters for immediate throttle response and smooth high rpm operation. Feeding the three lightweight inlet valves is a 39mm Keihin flat-slide carburettor which breathes through a large capacity airbox. Special feature on the YZ400F’s intake side is an innovative air valve which is designed to ensure easy starting when the engine is warm. A tube connects the machine’s inlet manifold directly to the airbox, bypassing the FCR39 carburettor. By pulling the air valve’s choke-type knob, air is fed straight from the airbox into the engine for easier warm starting.

Remove the stock fuel induction system, including the manifold and disconnecting all wire connections. It is up to the technician as to whether the gas tank should be removed or just raised up in the rear. Picture 1 2- You will need to disassemble the stock induction system to remove the pre-listed parts for re-use. 3- Verify the new manifold size is appropriate for your motorcycle by sliding it in place. Picture 2 Picture 3 4 5- Slide the MAP sensor in place, being sure not to pinch the orange rubber seal—some clean engine oil may make this easier. Install the cable guide and verify it is aligned with the throttle cable actuator. Once alignment is satisfactory, apply Loctite® 222 to the 10-24 x 1/4″ screws and tighten to 18-22 in-lbs. 4- Install the new O-ring into the throttle body. A light film of clean engine oil can be used to help hold the O-ring in place. Align the manifold to the throttle body, use purple 222 Loctite® on the 10-24 x 1″ socket-head assembly screws (with flat washers) and tighten them to 35-40 in-lbs. 6- Using the new S&S® supplied gasket, slide the S&S supplied intake air temperature (IAT) sensor in place. Use Loctite 222 on the T10 Torx button head M3 x .5 x 10mm screws and tighten to 6-8 in-lbs. Picture 4 Picture 5 Picture 6 5 7- For the stock throttle position sensor attach the “C” shaped spacer to the end of the throttle shaft, put a 4mm flat washer on each T20 Torx button head M4 x .7 x 12mm screw, apply some Loctite® 222 and torque screws to 18-23 in-lbs. 8- Install the new O-ring on the IAC motor. Lubricate the OD of the O-ring with a light film of clean engine oil. Put a 4mm flat washer on each T20 Torx button head M4 x .7 x 12mm screw, coat the threads with Loctite 222. Install the IAC motor and tighten the screws to 18-23 in-lbs. 9- Partially install the fuel injectors in the fuel rail. Be sure to orient the black O-rings to the rail and align the clocking tabs with their holes. It may be helpful to lubricate the O-rings with clean engine oil. See Picture 9. NOTE : These are special O-rings that seal pressurized gasoline. If you see one with damage or an abrasion—replace it immediately. Picture 7 Picture 8 Picture 9 6 10- Connect the Injectors to the manifold with a light squeezing action. Lubricate the O-rings with clean engine oil. Once in place, use Loctite® 222 on the threads of two 8-32 x 5/8″ slotted panhead screws and tighten to 15-20 in-lbs. 11- Install the backing washer and O-ring on the fuel supply tube. Lubricate the O-ring with clean engine oil. When the tube is in place, position the Y-shaped clip on the fuel rail and tighten the Loctite 222 coated T20 Torx button head M4 x 7 x 12mm screw to 18-23 in-lbs – Gently push the injectors downward toward the manifold to increase clearance for connecting the wire connectors. Cut the existing injector connectors from the motorcycle harness. Slide the sleeveing onto the injector harness. Slide heat shrink tubing on to each wire of the injector harness wires. Crimp the butt splices to the motorcycle harness. Move the heat shrinks over the splices and shrink with a heat gun. Slide the sleeve into place. Picture 10 Picture 11a Picture 11b Picture 12 Picture 12a 7 13- Put the stock manifold flanges on the manifold. YOU MUST USE THE S&S® RUBBER GASKETS ON THEM. Be sure to orient the tapered end towards the manifold and the flat end to the heads. 14- Hold the manifold up in its basic mounting position and connect all of the wiring harness connectors at this time. Install the manifold using the stock mounting flange bolts (from the primary side of the motorcycle) coated with Loctite® 242 and the new S&S cam side screws (1/4″ socket head, 5/16-18 x 3/4″). If a screw longer than 3/4″ is used, damage to the heads will result. Lightly snug all four manifold mounting bolts but DO NOT TIGHTEN AT THIS TIME. Connect the throttle cables and cruise control bracket (if applicable) at this time. NOTE: The Harley-Davidson® service manual for your model motorcycle will be helpful during this step. 15- Install the breather system now. On 4.00-inch bore or smaller engines the breather uses banjo fittings with hollow bolts and connects across the heads to the intake with a T-hose. This hose will need to be trimmed and have spring clamps attached as shown in photo. Torque the hollow bolts to 10-12 ft-lbs. On 41/8-inch bore or larger engines, install the sharp bent hose on the rear head and install the check valve with the white end towards the head. Mount the other hose on the black end of the check valve and connect it to the throttle body using spring clamps to secure the connections. Picture 13 Picture 14 Picture 15 8 16- Once the breathers are secure, install the fuel line per the factory service manual you are working with. Connect the battery and verify the fuel pump turns on to pressurize the system and there are no gas leaks, but DO NOT START THE ENGINE. At this time, PC software may also be used to verify sensor readings and adjust the throttle position sensor voltage if necessary. 17- Install two 242 Loctite® coated pipe plugs (included in kit) in the air cleaner backplate as shown in Picture 16. Torque to 35-45 in-lbs. Also, two pan screws coated with Loctite® 222 must be installed in the backplate in place of the enrichment device. See Picture 16a. Torque them to 12-18 in-lbs. Failure to install these screws could allow dirt and debris into the intake system. 18- Use a new gasket on the backplate and put it in place noting the number of shims required. Once you select the appropriate shims (included) mount the backing plate to the engine but DO NOT INSTALL THE SCREWS YET
