CLEANING
IMPORTANT: Before inspecting or assembling
powerhead, all internal components must be
completely clean and free of contaminants.
Remove any carbon accumulation from exhaust
port areas.
Remove any carbon accumulation from cylinder
head combustion chambers.
If cylinder walls are glazed from extended use,
use a rigid, medium grit cylinder hone to resurface
walls. Use slow RPM for best oil retention and ring
sealing. When finished, a cross hatch pattern of
22 to 32° should be visible in the cylinder wall.
The pattern should be uniform in both directions.
IMPORTANT: To avoid piston or cylinder block
damage, restore the chamfer to all port edges
using a ball hone or other suitable tool.
Use Gel Seal and Gasket Remover to remove all
traces of gaskets, adhesives, and Gel-Seal IIâ„¢
sealant from the cylinder block and crankcase.
Carefully remove any carbon accumulation from
the tops and ring grooves of the piston using
Engine Tuner. A ring groove cleaning tool can be
made by breaking an old ring and grinding its end
to an angle. DO NOT damage ring grooves while
cleaning.
Thoroughly wash entire cylinder block and crank-
case with warm, soapy water to remove all traces
of contaminants.
Air dry cylinder block and crankcase. Blow all
holes and passageways with compressed air.
Cover the cylinder walls with a liberal amount of
outboard lubricant to prevent corrosion.
