1. Remove both seats and the plastic seat pans under the seats. 2. Remove the engine cover 3. Remove the air-box by removing the cross-bar support that runs under the air-box to the framing on each side by the seat framing and disconnect the air box from the carburetor and from the plastic intake in the rear. 4. Disconnect the engine breather hose from the bottom of the air box 5. Set the air-box to the side 6. Disconnect the plug going to the stock carburetor, this is the electronic choke. Wrap the end left on the vehicle with electrical tape. 7. Cut the fuel line just above the fitting on the passenger side of the carb 8. Remove the side cover off the drivers side of the carb where the throttle cable goes in, see fig. #1 9. Pull the throttle cable out and then remove the throttle cable end from the throttle plate See Fig. #2 10. Loosen the clamp on the rear of the carb holding the carb on 11. Pull the carb out of the intake boot 12. Set OE carb to the side. 13. Push the new Carb into the intake boot making sure the carb is perfectly vertical and then tighten the clamp back up. The new carb is slightly larger than the stock one so some additional pressure will be needed to get it in. 14. Route all the breather lines connected to the carb down under the carb. 15. Connect the throttle cable onto the new carb but putting the cable end in the bottom hole of the throttle plate on the passenger side of the carb allowing the cable to ride in the slot in the plate and then turn the throttle plate clock wise allowing the threaded end of the cable to fit into the lower round hole of the throttle cable connection plate. See Fig. #3 16. Make sure you have a nut on each side of the plate turn the nut on the outside of the plate to take up the slack in the throttle cable then tighten the nut on the inside of the plate. See Fig. #3 17. Push the fuel line onto the fuel inlet on the passenger side of the carb and install the supplied clamp to hold it on. The fuel line will be a little hard to push on. 18. DO NOT ATTEMPT TO INSTALL THE CHOKE CABLE PARTS SUPPLIED IN THE KIT UNTIL AFTER THE CHOKE CABLE ITSELF IS INSTALLED AND READY TO SCREW INTO THE CARBUETOR. 19. To install the supplied choke cable, drill a 3/8″ hole in the dash on the left side of the steering wheel in a location convenient to your left hand. 20. Remove the plastic nut from the bottom of the choke handle on the choke cable. 21. Push the choke cable thru the hole you drilled and then slide the nut over the cable to the inside of the dash and reinstall back on the back of the choke mechanism. Some dash screws maybe needed to be removed to accomplish this

To install, remove the stock carb per Yamaha shop manual procedures. Remove stock throttle cables. Install Mikuni HSR carb into intake manifold and tighten manifold clamp. Install new HSR series throttle cables and adjust cable slack per Yamaha shop manual procedures. Hook fuel line to HSR carb and fasten clamp.* Start motorcycle and fine tune HSR carb for proper running per supplied Mikuni tuning manual. *NOTE: Mikuni HSR series carburetors are designed for gravity-feed fuel systems. You should bypass your stock fuel pump and directly feed your HSR carb right from the fuel petcock. We have noted, though, that you may not be able to get good fuel flow from your Road Star fuel tank in low-fuel situations. You may run your stock fuel pump with the HSR carb, but to do so requires the purchase and installation of an adjustable fuel pressure regulator (set at 1/2 to 1 lb. of pressure). These are available from most auto parts stores. The stock carb has 2 wires running to the lower rear of the float bowl , these were for a carb warmer, they are not used in this application. Unplug these wires at the main wire harness and retain with your stock carb. The Road Star ignition system uses data from the stock throttle position sensor (TPS) to manage your ignition timing. It is necessary to give the bike this information. You may do so by removing the TPS sensor from the stock carb, leaving it plugged into the main wire harness (the sensor must be fixed to a closed-throttle position), or you may locate the plug for the TPS on the main wire harness and test the leads – you will find one ground, one with .5V and one with 1.5V. Connect the 1.5V to the ground and this will give the bike the same information as stock fully closed throttle. The output of the OEM fuel pump is too high and will cause fuel overflow in the HSR carb, resulting in a possible dangerous fire hazard

The CRF/XR50 engineers never intended “large” people to be competitively thrashing their design. As a result, failed frames are becoming quite common at the track. Laid-out forks, tweaked, ill-functioning suspensions and bent frames are symptoms we’ve all witnessed. This CRF/XR50 frame kit addresses all these problems with not only a stronger framer but also with added knee-to-bar clearance for taller riders.. Features: • Heat-treated chromoly steel frame • TIG welded • Fully gusseted • Thicker-walled main tube that is also larger in diameter • Conservatively estimated at 4 times stronger than the stock unit • Race legal open cradle configuration, but with fully closed loop rear sub frame under the seat for added strength and safety • Stronger swing arm pivot area prevents wallowing • Frame is 1″ longer than stock, resulting in greatly enhanced handling characteristics This Chromoly 1″ longer frame with chromoly removable subframe is the off the hook! It features a detachable chromoly subframe with all hardware as well as a 1″ rise in gas tank and seat height for more more leg room and to allow bigger carburetor modifications. Extended frame also provides: • Much needed knee-to-bar clearance • Improved rider position • Better Center of Gravity • Better control Features: • Heat-treated chromoly steel frame • TIG welded • Fully gusseted • Thicker-walled main tube that is also larger in diameter • Conservatively estimated at 4 times stronger than the stock unit • Race legal open cradle configuration, but with fully closed loop rear sub frame under the seat for added strength and safety • Stronger swing arm pivot area prevents wallowing • Frame is 1″ longer than stock, resulting in greatly enhanced handling characteristics • Gas Tank is raised 1″ for added clearance

can fix it – let us help. The color combo that would have been featured here, had we not got rained on. As light as the morning precipitation was, a rainsuit seemed silly, and surely jeans and a leather jacket would be enough. However, at the crest of the peninsula, El Nino let his wrath be felt. A full-on downpour of Florida- like proportions dropped from the sky, without the benefit of gulf-stream warmth. Suddenly, wearing geeky-looking Gore-Tex seemed like a very good idea. Riding through six inch deep floodwaters at about 15 mph, the Aero kept a very even keel. The floorboards (first ever on a Honda) kept the feet drier than they would have been otherwise. After a brief stop at a military museum, we headed back to Honda’s HQ for a van ride to lunch at Hollywood’s House of Blues. Detail 101: Witness the huge chrome headlight/speedo assembly, with matching idiot lights set into the triple clamp. We couldn’t form much of a riding impression from our rain-soaked 30 mile jaunt, but we liked what we found. If you’re a big fan of the ACE 750, you’ll be a big fan of the Aero. Although the styling is not ground-breaking, it isn’t a carbon copy of you-know-who (hint: They’re based out of Milwaukee). The detail on the Aero is beautiful, with tasteful chrome accents and well-finished pieces. We hope to get the big 1100 back for a full test against Suzuki’s new Intruder 1500LC, Harley’s new Road King Classic, and all the other cruiser big boys some time this spring, after El Nino goes away … Manufacturer: Honda Model: 1998 Shadow Aero Price (two-tone): $9,995.00 Engine: liquid-cooled 45 degree V-twin, single crank pin Bore and Stroke: 87.5 x 91.4mm Displacement: 1099cc Carburetion: Two 36mm CV Transmission: 5 speed Wheelbase: 66.1 in Seat Height: 28.5 in Fuel Capacity: 4.2 gal with .8 gal reserve Claimed Dry Weight: 623 lbs

Oil Temperature and Gauge 2.1. Introduction My 1998 BMW R1100RT came with an LCD temperature gauge that shows horizontal black bars in a vertical motif, to indicate temperature. This is difficult to interpret at speed (how many bars are exposed?) and does not actually tell me what the oil temperature is. 2.2. Normal Operation The bike seems to run at 5 or six bars under normal conditions. It appears that the oil thermostat for the cooler is set to ’5 bars’. 2.3. Over Heating The LCD panel indicates that 8 bars is the maximum normal operating temperature. It would be useful to know what the actual temperature is. Modern oils have a normal operating temperature of approximately 110 degrees Celsius and will not show any serious degradationii at this temperature. The maximum sustained operating temperature (at the bearing surface) is approximately 130 degrees Celsius for any oil formulated in the past 5 years and some high performance synthetics will not appreciably degrade even at this temperature. However, the degradation curve is a polynomial and degradation will increase rapidly with increasing temperature. According to the oil’s formulation (pure synthetics will show the least increase with temperature), by approximately 160 degrees Celsius (or about 300 degrees Fahrenheit), oil degradation can be up to 10 times faster then at 110 Deg. C. 2.4. Scale To fix the ‘number of bars’ problem, I determined that an overlay with numbers would be the best idea. 2.4.1. Addendum The number scale became too much to maintain. Rather than this, I cut a mm or so wide stripe out of the self sticking stripping meant for the side of a car. Using a red material, I put it through the middle of the fifth bar of both the temperature and fuel display. The stripe is slightly smaller than the thickness of the bar. This allows me to tell when I am at normal operating temperature and when approximately half a tank is used

1. Raise the motorcycle and support it to enable the rear suspension to hang free. 2. Remove the stock rear link & struts. 3. Remove the link bearings and sleeves from the stock link with the exception of the bearings and sleeve in the middle of the link. You will be using the bearing & sleeve listed above in the middle position of the new link. This is the same bearing and sleeve that is used at the front of the Link. 4. Press the bearings into the new link making sure that the bearings are centered in the link. 5. Lubricate the bearings with high-pressure synthetic grease. 6. Install the sleeves in the same position as removed using the one listed above in the middle position. 7. Reinstall the link using the new bolt supplied in the kit in the middle position. 8. Torque all the bolts to the factory specifications. Torque the special bolt supplied in the kit to 70Nm, 50Ft-Lb. Blue Locktite is recommended. 9. As a rule of thumb the spring rate should be increased 0.5 kg or 28 lbs. in relation to the spring rate that is currently being used. This is a good starting point. Note: This kit is designed for single rider racing applications. The spring rate and dampening must be tailored for the individual rider weight, style of riding, motorcycle weight and track conditions. An experienced race mechanic using only the appropriate tools for removal and replacement of bearings and other components should only install this kit. Any questions can be directed to Attack Performance at the address and numbers below.
