1 . Ensure vehicle runs correctly through all rpm ranges and idles correctly before attempting any work. It is highly recommended that a pressure / flow test be carried out before & after installation of the VariReg to determine fuel system condition . Stock HD 300 kPa / 44 psi, VariReg as delivered 360 kPa / 52 psi Note: In some countries gas stations do not “final filter” the fuel & therefore we recommend that the fuel filter canister be replaced every 15,000 klms (10,000 miles). Restriction of the fuel by way of a blocked or partially blocked filter will result in difficulty in tuning or failure to obtain satisfactory results during tuning. Should you experience difficulties in tuning, see Diagnosing fuel filter and pump faults 2. Remove air filter cover, air filter and backing plate. Check Throttle Position Sensor value at completely closed throttle as best performance will be obtained at the nominated settings. This will require backing off the idle screw and cold start idle actuator and screw adjustment as described in the workshop manual. The original T.P.S. values should be recorded for possible future reference. To set TPS values without the HD breakout box see VariReg TPS Setting for Harley-Davidsons The T.P.S. values must be set to 1995 – 1996 175 mV (+/- 25mV) 1997 – 2001 275 mV (+/- 25mV) Record the original TPS value here. ………………..mV YOU MUST ENSURE THROTTLE PLATES ARE COMPLETELY CLOSED AND NO BINDING EXISTS IN CABLES to obtain the correct value setting. 3. Reset idle screws to approximate previous settings, no need to start the engine. 4. Complete full or partial fuel tank removal as described in workshop manual. 5. Remove stock fuel pressure regulator as described in workshop manual and leave Horn removed from vehicle until after tuning, this will allow ease of access to the regulator

1 RACING SERVICES 115 CARLINGFORD RD EPPING SYDNEY 2121 AUSTRALIA Part # EDU001 Type 3 Please note: These instructions refer to Type 3 Ducati VariRegs. Type 3 VariRegs may be distinguished by a hole & groove machined into the end face of the adjustment screw. VariReg -Variable Pressure Fuel Regulator Suitable for:- Ducati 916-998 / 748 all models. The Epicycle VariReg will allow a fuel pressure rate of 300 kPa (stock) to 540 kPa. By increasing the pressure available at the injectors, more fuel will flow thus richening mixtures. The available increase in fuel pressure is sufficient to allow the fitment of performance parts, without the high end lean condition normally experienced with the stock fuel pressure. This lean condition is the result of injectors that are too low in flow rate, and even when switched on continuously, are incapable of delivering the required quantity of fuel. Changes to the fuel mapping may be required when using this product. The increase in fuel pressure is variable by the owner and may be altered at any time as required. The unit comes pre-set at 450 kPa. It should be noted that the VariReg is designed for a maximum pressure of 540 kPa, but pressures in excess of 450 kPa require the fitment of the CORSA style high output fuel pump. ** Under no circumstances should the pressure exceed 450 kPa if using the standard road pump! ** Pressures may be set in the following manner. ** This method should be used as a guide only. Use of a suitable pressure gauge is recommended.** 1 . Rotate the adjustment screw “IN” (clockwise direction) using an 11mm or 7/16″ spanner until the head of the screw is seated against the body. Use a tommy bar in the 5mm hole in the side of the VariReg to prevent rotation of the body
