(Two screws (8) in the upper of the speed control plate (2).)
• Position the slot (7) on the fork lever just under the slot (6) on the
crankcase.
• Insert the injection pump (1) so that the control rod (10) should be

shown in the photo).
NOTE
• The sealant is applied to both sides of the soft metal gasket
shim. The liquid gasket is not required for assembling.
• Addition or reduction of shim (0.05 mm, 0.002 in.) delays or
advances the injection timing by approx. 0.009 rad (0.5 °).
• In disassembling and replacing, be sure to use the same
number of new gasket shims with the same thickness.
