Insufficient clearance between rocker covers and valvetrain components may cause engine damage not covered under warranty. It remains
the engine builder’s responsibility to verify all operating clearances.
12. Confirm pushrod adjustment according to manufacturer’s instructions and install pushrod cover retainers.
13. Place 17⁄8" o-ring and Viton® gasket in rocker cover base. See Pictures 8 and 9. Install top cover with 4 each 1⁄4" socket head screws, flat washers
and fiber washers provided. (Fiber washers go between flat washers and cover.) Apply Loctite® 242 or equivalent to threads and tighten in
X-pattern to 90-100 in.-lbs.
14. Remove covers from rear cylinder pushrods. Rotate engine to place pushrods at lowest point on cam with rear piston at TDC. Repeat procedures
described in Steps 5-13.
15. Replace parts removed for installation, start motorcycle and inspect for gas and oil leaks.
NOTE: Chrome scratches easily. Clean chrome with degreaser as necessary, then wash with hot soapy water. Rinse thoroughly before applying polish with
a clean cotton cloth. Many waxes and polishes contain abrasives which will scratch chrome. S&S recommends non-abrasive polish specially formulated for
chrome and has used Mother’s Chrome Polish with good results.
