Husaberg FS 650 (2004) Racing Exhaust System
Akrapovic Racing Exhaust System
for the Husaberg FS 650 (2004)
Swedish off-road performance on two wheels. The slightly exotic Swedish brand Husaberg is gaining ground on the competition year after year, and the companys orientation is starting to show results. The FS model is equipped to compete in Supermoto racing. The Husaberg engine is one of the strongest power plants around, and together with excellent handling offers dynamic riding and presents an exceptional challenge to the more popular brands. GOAL Supermoto motorcycles need light weight, lots of power and good brakes. The Akrapovic R&D department has developed a complete Akrapovic RACING exhaust system which will unquestionably contribute to the performance of the Husaberg with respect to all of the above mentioned factors. ABOUT AKRAPOVIC RACING SYSTEMS Exhaust system tuning is a popular modification, since it does not require any modification of the engine itself. With our complete exhaust systems we try to obtain even more power and torque out of the engine. This is confirmed by our Akrapovic RACING exhaust systems, which together with our EVOLUTION systems represent our top-of-the-line products. The header tubes are made out of stainless steel, while the collector and link pipe are made of titanium. For the Husaberg all of the tubes are conical section, which in this case ensures the optimal flow of exhaust gases. The components two header tubes, collector, link pipe and muffler are connected with freefloating joints held together with high-quality silicon-shielded Akrapovic tensioning springs. The muffler is the Akrapovic Supermoto shape, with a rounded outlet cap. The outer sleeve of the muffler is titanium, which blends beautifully into the lively Scandinavian color combination of the Husaberg. The interior of the muffler is also made entirely of titanium. The use of

high-quality materials such as titanium enables the production of exhaust systems at minimum weight while retaining their durability. Supermoto motorcycles are intended for dynamic riding and are designed to endure radical braking and acceleration. The Akrapovic dual carbon-fiber clamp ensures minimal vibration of the muffler during the sliding turns of Supermoto competition. Measurements of the Akrapovic RACING system on the Husaberg FS 650: power the design of the Akrapovic RACING system complements the Husaberg engine extremely well. This can be seen from both the power curve and the torque curve. The power curve shows a nice increase over the stock curve from 3500 rpm to around 5000 rpm, from where it runs essentially linearly. But the real difference can be seen starting at 7400 rpm, where the stock curve peaks. By installing an Akrapovic RACING system the max. horsepower jumps up to 62.1 HP at 7700 rpm. The max. increased power of 5 HP shows up in the overrev range at 8500 rpm. torque an even better result and the real advantage of our exhaust system is shown in the torque curve. A completely linear increase in the range from 3500 to 5500 rpm means huge reserves of torque when accelerating from low revs, and less work for the rider. The graph also shows the overall widening of the torque curve, which in combination with the increased power offers an extremely dynamic package such as is necessary for spirited Supermoto riding. In addition to the major performance increase, the Akrapovic RACING exhaust system for the HUSABERG FS 650 also offers an aesthetic refinement which is never out of place on any motorcycle. The satin sheen of the titanium muffler looks great on the Swedish Supermoto rocket. And since every gram counts in SM, with our system you will save a further 1.38 kg on the overall weight of the bike. And we shouldnt forget to mention the sound. The Akrapovic RACING system joyfully proclaims the new-found freedom of the single-cylinder engine.

INSTALLATION INSTRUCTIONS
BEFORE INSTALLING CHECK SCHEMATIC OF THE EXHAUST SYSTEM!
IF ANY ITEMS IN THE AKRAPOVIC EXHAUST SYSTEM PACKAGE ARE MISSING PLEASE CONTACT YOUR AUTHORIZED DEALER. KEEP THE SCHEMATIC FOR FUTURE REFERENCE. THESE INSTALLATION INSTRUCTIONS MUST BE READ CAREFULLY IN ORDER TO ENSURE PROPER INSTALLATION AND OPERATION OF THE AKRAPOVIC EXHAUST SYSTEM. THE EXHAUST SYSTEM CAN BE EXTREMELY HOT. ALLOW THE MOTORCYCLE TO COOL DOWN BEFORE BEGINNING INSTALLATION. WE ADVISE YOU TO LEAVE INSTALLATION TO A QUALIFIED SERVICEMAN. IMPROPER INSTALLATION MAY RESULT IN A SHORTER LIFETIME OF THE EXHAUST SYSTEM AND/OR DAMAGE TO THE MOTORCYCLE.
REMOVAL OF STOCK EXHAUST SYSTEM 1. 2. 3. 4. 5. 6. 7. put the motorcycle on a side stand, we recommend a racing stand for easier access to the muffler unscrew the bolt on the left rear panel (panel remains on the bike) (Figure 1) unscrew and remove the bolt from the metal muffler bracket (Figure 2) unhook the spring on the link pipe (link pipe muffler joint) and remove the muffler (Figure 3, 4) unhook the spring on the collector (collector header tubes joint) (link pipe and collector are joined) (Figure 5) unscrew and remove the bolt from the metal bracket for the link pipe and remove the link pipe + collector (Figure 6, 7) unscrew and remove the bolts on the flanges of both header tubes and remove the stock header tubes (Figure 8, 9)
INSTALLATION OF THE AKRAPOVIC RACING EXHAUST SYSTEM installing the header tubes: 1. correctly position the flanges with the header tubes for installing the springs (Figure 10, 12) and tighten the flange (both header tubes) (Figure 11, 13) 2. attach the springs (Figure 14, 15) installing the titanium collector: 1. slide the collector onto the header tubes and attach the springs (Figure 16, 17) installing the titanium link pipe: 1. insert the press-on nut into the link pipe (Figure 18) 2. coat the interior side of the input of the titanium link pipe with Akrapovic ceramic anti-seizing grease 3. slide the link pipe onto the collector (Figure 19) 4. hand-tighten the bolt on the metal bracket for the link pipe (Figure 20) 5. attach the spring at the link pipe collector joint (Figure 21) installing the titanium muffler: 1. attach the stick-on washer under the left panel (Figure 22, 23) 2. coat the interior side of the input to the muffler with Akrapovic ceramic anti-seizing grease 3. slide the muffler on and attach the springs (link pipe muffler joint) (Figure 24) 4. correctly position the carbon-fiber clamp and slide it onto the muffler - bear in mind the right offset of the carbon-fiber clamp viewed from the rear. (Figure 25) WARNING: open the clamp to slightly wider than the diameter of the outer sleeve of the muffler do not scrape it along the muffler outer sleeve! 5. attach the carbon-fiber clamp to the stock chassis hanging bracket use the bolt, washer and rubber spacers supplied in the Akrapovic kit. Do not fully tighten. Make sure the additional parts from the Akrapovic kit are correctly installed. (Figure 25) 6. make sure the link pipe and header tubes are not touching the engine or frame (Figure 26) 7. position of the correctly installed Akrapovic RACING system (Figure 27) final installation: 1. tighten the bolts on all of the brackets and clamps to which the exhaust system and the other dismounted parts of the motorcycle are attached 2. clean grease spots: a. muffler titanium outer sleeve, titanium collector and titanium link pipe: use a soft cloth sprayed with a multipurpose spray lubricant (WD-40 or equivalent) b. stainless steel header tubes: use a soft cloth sprayed with a contact cleaner; then wipe with a soft dry cloth Cleaning will prevent spots from burning onto the surface. Do not use aggressive chemical cleaners, because they can damage the sticker. 3. replace all of the dismounted stock parts and cowlings in the reverse order from the order in which they were removed 4. Check the operation of the brakes and suspension. Make sure all the bolts are sufficiently tightened. In case the exhaust system touches the cowling or other parts repeat the adjustment of the exhaust system or contact your authorized dealer.

IT IS NORMAL IF WHITE SMOKE COMES OUT OF THE MUFFLER ON FIRST OPERATION. DO NOT STAND BEHIND THE MUFFLER ON FIRST OPERATION.
MAINTENANCE OF THE AKRAPOVIC EXHAUST SYSTEM 1. Clean the titanium muffler outer sleeve with a multi-purpose spray lubricant (WD-40 or equivalent ). Do not use aggressive chemical cleaners, because they can damage the sticker. A change in the color of the exhaust system is normal due to the high temperatures. The wearing out of the muffler silencing material depends on the type of the motor and riding style. Contact your dealer/serviceman if visible changes appear on muffler's outer sleeve or the noise level is increased. Periodically make sure all the bolts and springs are sufficiently tight.
