Quick Guide to Maintenance Coolant liquid Coolant liquid -30ºC Crankcase oil (10w40) 500 cc. Electrode separation 0.6 mm. Forks suspension oil SAE 5 (Summer) SAE 2.5 (Winter) Fork suspension oil quantity200 cm3 Shock absorber spring length96 mm Front wheel pressure Standard 0.400 bar Competition 0.370 bar Rear wheel pressure Standard 0.350 bar Competition 0.300 bar -9- 1 Fuel – Petrol/oil mixture The motorcycle is fitted with a two-stroke internal combustion engine. This type of engine requires a mixture of petrol and oil. To ensure the correct working of the engine, the following are recommended: – Use high quality petrol, with an octane rating equal to or above 90 (RON + MON)/2 or 98 (RON). – Use 2T synthetic oil. Warning: – If the recommended oil is not available, use semi-synthetic oil. – Do not mix different oil-types. Mixture ratio: oil, 1.5% of petrol volume (50 parts petrol to every 0.75 part oil). Note: we recommend first preparing the mixture in a suitable container and then filling the fuel tank. Fuel tank This has a rapid access cap A and a vent hose B to allow gases produced in the tank to escape. – To open the cap, lift the clip in the direction shown by the arrow and turn to the left. Warning! Regularly check the cap seal and vent hose to ensure they are leak proof. Risk of spillage. -10- 3 2 Reserve Open Closed Fuel tap This has three positions: open, closed and reserve. The diagrams below show the position of tap A for each case. A Gear shift The motorcycle has a two- speed gearbox, which may be selected manually when the motorcycle is stationary, by moving the lever A in a horizontal direction, as shown by the arrow. Note: Select the gear according to the characteristics of the track

Refer to the Service Manual and follow the MAXI-FUSE instructions to replace the maxi-fuse and right-side cover. After servicing brakes and before moving motorcycle, pump brakes to build brake system pressure. Insufficient pressure can adversely affect brake performance, which could result in death or serious injury. (00279a) After servicing the brake system, test brakes at low speed. If brakes are not operating properly, testing at high speeds can cause loss of control, which could result in death or serious injury. (00289a) Maintenance and Cleaning Chrome parts must be maintained regularly to ensure that they keep their original shine and luster. 1. Clean heavily-soiled wheel surfaces using Harley Wheel and Tire Cleaner, part number 94658-98, applied with Harley Wheel and Spoke Brush, part number 43078-99. 2. Thoroughly clean chrome with a good quality chrome cleaner, such as Harley Bright Chrome Cleaner, part number 94683-99. 3. After cleaning and polishing, seal the finish with a good quality sealer such as Harley Glaze Polish and Sealant, part number 99701-84

Cylinder Wall MACHINE CRANKCASE Crankcase Boring Preparation NOTE During final assembly of the engine, Harley-Davidson recommends replacing the OE cylinder studs with Screamin’ Eagle High Tensile Studs (16505-01). 1. Remove cylinder studs from the engine crankcase. 2. Mask off all bearings and oil holes to prevent debris and contaminants from entering those areas. 3. Inspect and clean engine case mating surfaces. 4. See Figure 6. Reassemble engine case with OE screws, except the top center screw between the cylinders, and tighten to specifications listed in service manual. NOTE To prevent damage to crankcase boring tool, it is important to replace the top center screw with a modified top center screw (1093). This screw is included in the Crankcase Boring Tool Kit (94419-06) and can be purchased separately from a Harley- Davidson dealer. 5. Install modified top center screw (1093) between the cylinders and tighten to 50-90 in-lbs (5.6-10.2 Nm). 6. See Figure 1 and Table 1.
