Use caution to prevent damaging reed valve
assemblies.
IMPORTANT: DO NOT disassemble reed valve
assemblies. Damaged reed plates are not ser-
viceable and are replaced as an assembly.
Inspection
Inspect the leaf plate assemblies for damage or
contamination:
• Leaf plates must not be distorted.
• Leaf valve must not be cracked or chipped.
• Leaf plate stops must not be distorted or loose.
• Leaf plate assemblies must be clean.
Inspect the intake manifold. All gasket surfaces
must be cleaned, smooth, and free of nicks. Use a
machinist’s straight-edge to check flatness in all
directions. Surface must be flat, ±0.004 in. (0.10
mm).
Assembly
Remove old adhesive from reed valve retaining
screws.
Prime screw threads with Locquic Primer and let
dry. Apply Nut Lock to threads. Position reed
valve on reed plate and install screws. Tighten
screws to a torque of 30 to 42 in. lbs. (3.5 to 4.7
N·m).
Installation
Place reed plate assembly on cylinder/crankcase.
Apply Nut Lock to screws. Install all screws.
Tighten the center screws first and expand out-
ward. Tighten in stages to a final torque of 96 to
120 in. lbs. (11 to 13.5 N·m).
Install electrical harness base screws.
