2. Install the gasket to the crankcase.
3. Install the reed valve assembly, insulator and
clamp to the crankcase.
4. Install the four carburetor insulator mounting
bolts (3) and tighten to the specified torque in
a crisscross pattern:
6.6 lbf·ft (9 N·m, 0.9 kgf·m)
After installation, check for secondary air leaks
around the reed cage and insulator.

Cylinder Installation
1. Clean off any gasket material from the gasket
surface of the crankcase, being careful not to
let any material fall into the crankcase.
Be careful not to remove any metal from the
gasket surface.
2. Remove the shop towel. Do not let any gasket
debris fall into the crankcase.
3. Place the cylinder base gasket (1) and dowel
pins (2) on the crankcase.

4. Lubricate the piston and ring with 2-stroke
oil. Align the ring end gap with the piston ring
pin (3) in the ring land and slip the cylinder
over the piston while compressing the piston
ring.
Do not rotate the cylinder, since this may
cause the piston ring to snag a cylinder port
and break.

Before tightening the cylinder nuts, make sure
that there is no clearance between the cylinder
and crankcase mating surface.
5. Install the four flange nuts (4) and tighten to
the specified torque in a crisscross pattern in 2
or 3 step.
20 lbf·ft (27 N·m, 2.8 kgf·m)
Be careful not to overtighten the mounting
nuts-this is the most common cause for leaks
here.

6. Install the following:
– expansion chamber (page 67)
– carburetor (page 92)
