[2] HALF-FLOATING HEAD COVER

This engine employs separate type crankcases - the
crankcase 1 (1) with combustion part and the crankcase
2 (2) which supports the crankcase 1 (1) and reduces
noise.
Since it is a hanger type, you can easily assemble /
disassemble it. The cylinder is a linerless type which
enables good cooling operation, less strain and good
abrasion resistance.
(1) Crankcase 1
(2) Crankcase 2
The rubber packing is fitted in to maintain the head
cover 0.5 mm (0.02 in.) or so off the cylinder head. This
arrangement helps reduce noise coming from the
cylinder head.
