The rectan- gular tab fits in the corresponding knockout around the gasket groove in the head. 28. See Figure 3-57 . Use cable ties (1) to help retain gasket as shown. 29. Visually check to verify spark plug hole gasket (2) is in place. Spark plug hole gasket must be installed with double lip side facing cylinder head to avoid oil leaking into spark plug hole.
(00547b) NOTE To aid in assembly, use a small amount of crankcase sealant to hold positioning of spark plug hole and cam cover gaskets (excluding camshaft half-moons) during assembly. 30. Apply a 1 mm (0.04 in.) bead of crankcase sealant along gasket recesses in cylinder head, not including camshaft half-moon areas. Cam cover gasket must stay in place. A small amount of sealer, lightly applied will help. 3-32 2009 VRSC Service: Engine For the front cylinder, verify that: a. The single copper link (6) on the cam drive chain straddle the single dot (5) on the intake cam sprocket. b. The single copper link (1) on the cam drive chain straddles the single dot (2) on the exhaust cam sprocket. c.
The two dot timing line (4) on the intake cam sprocket is aligned with the one dot timing line (3) on the exhaust cam sprocket. d. The front intake and exhaust cam lobes (18, 19) are positioned as illustrated. NOTE pare lobe positions of each cam shaft to Figure 3-49. If g marks are correct but camshaft lobes are incorrect, the sprocket could be installed incorrectly on the camshaft. Remove TAPPET COMPRESSING TOOL (Part No. HD- 45491). Install front cylinder cam chain tensioner and tighten to 100 Nm (74 ft-lbs). Remove TDC POSITIONING TOOL (Part No. HD-45653) from front cylinder spark plug hole. Check valve lash and adjust as necessary. See 1.25 VALVE LASH.
