After 1-2 hours of operation,
valve adjustment should be check-
ed. Adjust the valves as shown in
the Engine Maintenance Section.

equipped with a breather nipple.
It's recommended that a length of
silicone tubing be attached to this

Do not dismantle the engine.
The Multi-Cylinder Saito engines
are assembled utilizing special
jigs and tools. If it becomes
necessary to disassemble the
engine proper due to crash
damage or any other reason,
please forward your engine to
the Horizon Service Center.
Normal engine maintenance, such
as adjusting the valves or carbure-
tor maintenance, is permissible
without voiding the warranty;
however, disassembly of the
cylinders, crankshaft, and cam
gear assembly should be done
only by the Saito Service Center
because of the special jigs
andtools reguired. If you have any
questions concerning maintenance
procedures, please contact the
Horizon Service Center at:
(877-504-0233).
Our technicians will be happy to
advise you on maintenance issues.
Timing and cam gear alignment
should also be done by the Saito
Service Center.
After approximately one hour of
operation, tappet gap adjustment
may be necessary. Adjust the
valves to a clearance of
.03mm-.10mm (.002"-.004")
using the supplied gauge. The
valves must be adjusted with
the engine cold due to thermal
expansion.
