MAINTENANCE AND TUNE-UP PRO- CEDURES This section describes the servicing procedures for each item of the Periodic Maintenance requirements. AIR CLEANER I Inspect every 6 000 km (4 000 miles, 6 months) and replace every 18 000 km (11 000 miles, 18 months) . • * Remove the seat. (LF6-7) • * Lift and support the feul tank . (C-74-65) • * Remove the air cleaner box cap O. • * Remove the air cleaner element O. • * Carefully use air hose to blow the dust from the cleaner ele- ment. CAUTION Always use air pressure on the throttle body side of the air cleaner element . If air pressure is used on the other side, dirt will be forced into the pores of the air cleaner element thus restricting air flow through the air cleaner element . PERIODIC MAINTENANCE 2-5 2-6PERIODIC MAINTENANCE • * Reinstall the cleaned or new air cleaner element in the reverse order of removal . CAUTION If driving under dusty condition, clean the air cleaner element more frequently. The surest way to accelerate engine wear is to use the engine without the element or to use a ruptured element. Make sure that the air cleaner is in good condition at all times. Life of the engine depends largely on this component! NOTE: When cleaning the air cleaner element, drain water from the air cleaner by removing the drain plug . SPARK PLUG Inspect every 6 000 km (4 000 miles, 6 months) and replace every 12 000 km (7 500 miles, 12 months) . No. 1 (FRONT) SPARK PLUG REMOVAL • * Remove the radiator mounting bolt O. • * Move the radiator forward. • * Remove the spark plug cap O. NOTE: Be careful not to damage the radiator fins .

INSTALLATION Prepare the Motorcycle for Service To prevent accidental vehicle start-up, which could cause death or serious injury, disconnect negative (-) battery cable before proceeding. (00048a) 1. Follow the Service Manual instructions to disconnect the negative (-) battery cable. Remove Rear Brake Caliper Remove the Brake Pads 1. For models equipped with saddlebags: Remove the right-side saddlebag. Refer to the SADDLEBAGS section of the Service Manual. 2. Remove the rear master cylinder reservoir cover. 3. Pry both the inside and outside pads away from the brake disc and toward the caliper assembly to push the caliper pistons back into their bores. Use steady pressure to prevent scoring the brake disc. Pry between the pads and the brake disc. 4. When the pistons are fully retracted into their bores, pull the pad pins out to allow the pads to drop from the caliper assembly. Note the pads’ original orientation for installa- tion. 5. Install the cover on the rear master cylinder reservoir. NOTE Place a container under the brake caliper to catch brake fluid released when removing the brake line from the caliper. 6. Remove the banjo bolt fastening the rear brake line to the stock rear brake caliper. Save the banjo bolt for brake caliper installation and discard the two steel/rubber gas- kets. Remove the Stock Rear Brake Caliper 1. Apply isopropyl alcohol to the rubber bumper on the brake caliper to ease removal. 2. Lift the stock rear brake caliper toward the front of the motorcycle. The notch in the caliper must clear the weldment on the swing arm. 3. Remove the caliper from anchor weldment on rear swingarm. Inspect Pad and Pins 1. Inspect the brake pads. If friction material above the backing plate on either pad is 0.040 in. (1.02 mm) thick or less, replace the set. Follow the instructions in the Service Manual. 2. Inspect pad pins for wear and grooving. If wear is more than 0.015 in. (0.38 mm), replace both pins. 3. Inspect the brake disc and, if necessary, follow the instructions in the Service Manual to replace the brake disc. Install the Rear Brake Caliper NOTE Pay close attention to all warnings, cautions, and torque specifications in this instruction sheet and in the service manual when installing this rear brake caliper. NOTE Apply isopropyl alcohol to the rubber bumper for ease of installation. 1. See Figure 1. Position the caliper (1) between the brake disc and the rear fork.

Start by loosening the rear cylinder down tube bolt located on the top of the old mufflers center collector in front of the rear tire. 2. Remove both of the front cylinder exhaust pipe head nuts and set them to the side for reuse with the MAC exhaust system. 3. Remove the right side passenger’s foot peg. Set the foot peg aside as you will need to reinstall it. 4. Remove the left side passenger’s foot peg. Set this foot peg aside as it will also need to be reinstalled. Note: When you remove this bolt the entire exhaust system will be loose and may fall. You will need to support the old exhaust at this point to keep from injuring yourself. Gently move the old exhaust system side to side to remove it from the rear cylinder down tube. Once the exhaust system is loose from the down tube remove the system from under the Virago. 5. Remove the bolt holding the rear brake pedal in place and remove the brake pedal from the motorcycle. Note: Set both the bolt and the pedal aside for reinstallation. 6. Next loosen the nut on the drivers right foot peg, 1 full turn to start with. Then remove the rear nut on the same foot peg. (Note: The bolt that this nut is on goes completely through the motorcycle. This is the center stand mounting bolt.) Now remove the front nut and set both aside for reuse with the MAC system. 7. Install the center stand stop bracket under the left passenger foot peg. Install this bracket with the 90° bend facing down and towards the rear tire. (Note: Center stand sop bracket in provided in the hardware kit and is approx. 5″ long with a 90° bend in it.) Adjust the bracket by one of the large bolts through the foot peg then through the bracket and then install it into the stock location. Put on one of the washers and a nut and snug up the nut. Lower the center stand until the center stand come in to contact with the bottom of the bracket. Tighten the nut until it will hold the bracket securely. 8. Install the rear down tube clamp onto the rear muffler and install the medium sized nut/bolt/washer onto the clamp just finger tight. 9. Install the (2) small bolts into the channel bracket on the rear muffler. Install the rear mounting bracket onto the two bolts and then install the washers and nuts onto each. Tighten the (2) nuts only slight amount so that you can slide the bracket front to rear to insure that when you install the bracket you position it properly. 10. Slide the rear pipe onto the rear down tube about ¼”to ¾” past the pre-cut slots on the rear muffler pipe. Slightly snug the clamp making sure that the position of the bolt and nut will not interfere with any moving parts. The final position of this bolt can hit the tire if it is not positioned properly. 11. Install the other large bolt into the right passenger and then through the top hole in the rear muffler mounting bracket. Insert the bolt into the stock location and install the washer and the nut. 12. Align the rear muffler and you can then tighten the nuts on the rear muffler mounting bracket, the cylinder down tube and the right side passenger foot peg.
13. Install the front muffler on the rear most mounting bolt of the drivers foot peg and put the stock nut back onto the bolt. Hand tighten the bolt only at this time. Note: Install the nut at this time is only to support the muffler and to insure that the pipe does not fall on the ground while you complete the next step. 14. Lift the front head pipe into position and start the stock nuts onto the studs. It is strongly recommended that you install new exhaust gasket at this time. Note: The new exhaust gaskets are not included in the kit but are available at your local Yamaha Dealer. After gaskets are installed hand tighten the front head pipe. 15. Remove the nut from the drivers foot peg bolt and reinstall the drivers foot peg. Note: Hand tighten only at this time. 16. Finish tightening the nuts on the front head pipes. (Install these nuts according to Yamaha’s Factory specifications.) Once the nuts are tightened on the head pipe you can then tighten the drivers foot peg nuts. 17. Reinstall the rear brake pedal and tighten the bolt that holds it on to factory specifications. 18. Check all of the bolts that you have installed of removed to insure that they are tight. 19. Start the motorcycle and check for any leaks. 20. You are finished with your new MAC Exhaust System.
