The following instructions should be read in their entirety before beginning installation. If you are unsure of performing any step described, please contact your dealer.

Installation Instructions:

Step 1	Disconnect battery.
Step 2	Unplug the electronic control unit from the wiring harness on the engine.
Step 3	Disconnect throttle rod assembly by removing it from the air horn and the throttle arm, unscrew the white plastic piece from the throttle arm end and set this piece aside. For 2.5 L models, remove and save the black slotted piece on the other end, also.
Step 4	Remove the three bolts that attach the electronic control unit to the air horn, then remove it from the air horn, but leave the control unit mounted to the bracket, save the bolts for later steps.
Step 5	Locate and remove the bolts that attach the air horn to the base plate. Remove air horn by tapping gently on it to break it loose from the gasket.
Step 6	Remove the two bolts attaching the fuel regulator to the base plate, save bolts, DO NOT remove it from the fuel rail at this time.
Step 7	Locate and remove all remaining screws on the base plate.
Step 8	Remove base plate and reed blocks from engine crankcase, set reed blocks aside for inspection.
Step 9	Inspect reed petals on reed blocks, if any are chipped or burned on the edges, it is advisable to replace them now, making sure they seal correctly.
Step 10	Clean the crankcase mounting surface of any gasket material.
Step 11	Remove the (6) #10 screws from the cover plate of the SVS. Lift cover and remove slide assembly. Set these parts aside.
Step 12	Locate the 1/4-20 x 3/4 cap screws in kit. Install the reed blocks to the SVS base plate with a new gasket, DO NOT torque tight reed blocks to base.
Step 13	Locate the remaining 1/4-20 x 3/4 cap screws, (4) heavy washers are supplied to be installed under the mounting screws located in the center of the base plate. It is very important that the washers are in place or damage will occur to the base plate. Install the SVS base plate with reed blocks to the engine crankcase. DO NOT torque tight base plate at this time.
Step 14	Once the base plate is installed, remove one screw at a time from each side of each reed cage and apply loctite to the threads, reinstall and torque to 60-inch pounds evenly.
Step 15	Tighten the remaining SVS base plate screws, working from the middle to the outer screws evenly, and torque to 60-inch pounds, loctite should be used.
Step 16	Locate the throttle slide assembly, lubricate both sides with light oil, install slide assembly into SVS base plate and slot in bell crank arm, making sure it is free of any dirty materials that may cause binding of throttle assembly.
Step 17	Locate the SVS outer cover plate, install with (6) #10/24 x 7/8 stainless cap screws and lock washers supplied in the kit, loctite and torque to 25-inch pounds.
Step 18	Install the electronic control unit to the 'starter' side of the SVS base plate. Loctite and torque to 60-inch pounds, make sure bolts do not bottom out in the base or damage may occur.
Step 19	Plug the electronic control unit back into the engine’s wiring harness. Make sure the ground wire for the ECU is properly installed and tight.
Step 20	Mount the fuel regulator onto the SVS base plate with the same bolts used during disassembly. Loctite and torque to 40-inch pounds. Note: Cut 3/4" to 1" off the rubber fuel line on the pressure side of the fuel rail to ensure a proper fit, tighten hose clamp. Reconnect battery power and turn on the fuel pump, making sure you have no fuel leak.
Step 21	Reconnect the yellow tygon hose coming from the center bearing scavenge system to the fitting next to the bell crank assembly on the SVS base plate. Attach fuel pressure regulator vacuum hose to the nearest elbow on the top of SVS, then attach the ECU vacuum hose to the other elbow on the top of SVS.
Step 22	Locate the throttle rod and heim joint supplied in the SVS kit. If you are installing the SVS on any engine with a fixed timing advance, refer to step 23. If you are installing the SVS on any engine with a mechanical advance, refer to step 24.
Step 23	Locate the white plastic barrel that was removed during disassembly and screw it onto the opposite end of the throttle rod where the heim joint is located, until it has fully threaded into the barrel. With both the SVS throttle slide and the throttle arm on the engine in the fully closed idle position, adjust the throttle rod length to the preferred mounting hole in the bell crank assembly. Don't forget the jam nut, the two holes are provided for those who prefer a fast or a slow moving throttle. Once you have adjusted it to the desired position and length, install the throttle rod with the screw and spacer provided. Note: It is very important to loctite the screw that attaches the joint to the bell crank. Tighten to 60-inch pounds of torque.
Step 24	Locate the white plastic barrel that was removed during disassembly and screw it onto the opposite end of the throttle rod where the heim joint is located, until it has fully threaded into the barrel. Locate the black slotted piece that was removed during disassembly and replace the heim joint with the slotted piece, and don't forget the jam nut. With both the SVS throttle slide and the throttle arm on the engine in the fully closed idle position, adjust the throttle rod length so that the slotted piece will not move the throttle slide on the SVS before the advance arm moves. The throttle arm should move the length of the slot. On these models, SVS provides for a backlash spring. Note: The spring is not to be thought of as a return spring, its purpose is for backlash.
Step 25	Make sure that the throttle stop screw on the engine is adjusted so that it will not allow any extreme pressure on the SVS throttle slide in the wide-open position. Adjust the idle stop screw in the same manner, also check for any binding that may occur in the action of the throttle. This includes both the control box and cable, or a foot throttle and cable. If any binding does occur, identify the cause and correct the problem.
Step 26	The SVS kit provides (3) 1/2" spacers and (3) outer flange rings. By changing the length of the intake tract, you will find the best performance for your application. With the SVS, the combinations are endless.
Step 27	Use loctite when mounting any spacer directly to the base. Using the correct screw lengths provided will ensure trouble-free operation.
Step 28	Look over the entire engine to make sure you have not left anything loose or out of place. If so, correct it now. It is very important that the installation instructions be read and understood by all who perform the installation process.
Step 29	Start engine and adjust the idle speed to your desired RPM by adjusting the set screw on the front of the bell crank.
