The right side vent hole (as the tank sits when installed on the bike) should be plugged with the threaded plug and gasket.
182The rear tank is now placed over the rear frame and lowered in place so the rubber mounts are lined up with the slots in the tank. Before the tank is bolted in place the previously positioned vent hose is connected to the left-hand side of the tank using a new banjo bolt and two new gaskets. Lift the tank slightly to install the vent fitting.

TIP: Slightly grease the two round rubber mounting donuts.

183The tail tank is now bolted in place with two M8x25 bolts and washers into the threaded rubber mounts. Install the locking gas cap.
184Install the center tank cover.
The original rubber grommet for the oil tank filler neck is installed on the new tank cover and the oil cap removed. Place the new tank cover down over the oil tank filler and bolt the cover in place at the front near the head tube with the original screws (torx25). The oil cap can be reinstalled. Two of the original sheet metal nuts from the original cowling should be installed on the forward edge of the tank cover.
185The tank cover is secured at the rear as at the front using the original screws (torx25).
186The reserve pickup tube should be removed from the new fuel petcocks. To remove the reserve tube the filter should be unscrewed, the plastic tube removed and the filter screwed back in place. The o-ring seal should be slid onto the petcock over the filter, and the petcock installed into the tank using two M6x16 button heads. The petcocks should be installed onto both the left and right fuel tanks. You will notice that there are different right and left side petcocks. Once all the tanks are installed, check that all fittings are tight.
187Onto the top of the left side tank install two brass fittings with a gasket for the vent hose connections. Install the one remaining fitting into the right side tank. Along the inside top edge of the tank the self-adhesive foam tape is installed.
188The modified plaques are installed onto the front fuel tanks with one each M5x20 countersunk screw. When the plaques are in tightened in place the BMW logo can be reinstalled.
189On both the left and right tank mounts the remaining four round rubber mounting donuts are installed with four M8x16 shallow head Allen head bolts. Into the mounting hole near the rear of each tank install the large rubber grommet. The tank is installed from the rear and slid forward onto the rubber donuts, then secured with an M8x40 countersunk bolt and the special machined aluminum bushing. If necessary the tanks can be spaced out from the center tank cover by placing some of the remaining turned down M8 washers underneath the round mounting donuts.
190The fuel tank vent lines are installed as follows:

(1) Front left tank
(2) Right side tank
(3) Open end which is led upward into the faring.

191Connect the vent from fig. 190 (2) to the right side tank. After placing the vent through the frame to the left side the vent can be secured to the crossbar with cable ties.

Be careful not to pinch off the hose!

192Connecting the left side vent lines. Connect to the rear fitting the vent line from the rear and central tank. To the front fitting connect the hose coming from the right side tank. The hose (no. 3 from fig. 190) is led upward inside the faring and near the top curved back to point downward. Be sure there is clearance for full steering from stop to stop. Secure the hoses with cable ties, being careful not to pinch the hoses.
193Install the center cowl fiberglass piece. The cowl is installed with two M5x16 button heads and four large washers. Two of the washers are placed under the cowl, between the cowl and the frame, and two on top. the bolts are carefully screwed into the two fixed rivet-nuts in the rear framework.
194Assemble the seat.
At the front of the seat install the aluminum tab. Place the tab onto the underside of the seat and mark the two holes. Drill the holes to 6.2mm diameter. The tab is bolted to the seat with two M6x16 buttonheads, washers and locknuts. The two washers and locknuts are installed from inside the tool storage compartment in the seat.
195In the rear of the seat the quick release mechanism is installed. The pin is placed through the machined aluminum bushing and installed through the hole in the rear of the seat. Then the star washer is pushed onto the quick release pin to retain the pin in the seat.
196The seat is then installed from the rear and slid forward such that the tab slides into the bracket on the framework. Once the seat is slid in place the quick release pin is locked by turning 90 degrees.
197Remove the original wires from the old turn signals. Remove the lens and pull the lamp holder from the housing, unplug the wires and then pull them out from the turn signal housing.
198Installation of the front mini-turn signals.
The front turn signals are located in the center of the small raised areas of the sides of the faring. Mark and drill a 10mm hole. Mount the turn signals housings with the washer and nut supplied with the signals. Make sure the drain slots in the lamp housing are facing downward. (The right and left side lamps are different) Place the original wiring into the new signal lamps, plug them into the bulb holders and replace the lens.
199Install the oil cooler screen into the lower opening of the faring. Place the screen into the opening, mark and drill the four holes with a 3mm drill. The screen is now bolted in place with four M3x10 button heads, large washers and locknuts.
200Place the headlamp cover in place on the faring, mark and drill five 2.4mm holes that will be used to secure the cover. Place foam tape all the way around the opening and punch through the foam where you have previously drilled the five holes.
