While Operating
GUARANTEE
This engine is constructed from the very
best materials available and to the very
highest engineering standards, using
the most advanced precision machinery.
However, the extremely high stresses
imposed by car racing operation under
very severe conditions, as well as
stresses which are exacerbated by the
use of powerful fuels containing very
high concentrations of nitromethane,
constitute hazards which are beyond a
manufacturer's control. Accordingly, we
regret that it is not possible to extend
our usual warranty terms to this
particular engine -i.e. no guarantee is
offered against material wear, or damage
resulting from, actual use.
As delivered, the engine has the
carburetor lightly fit into its intake.
Secure it changing its angle according
to the car chassis.

The MAX-21XZ-R is expressly designed for 1/8
On-Road Racing. All the major parts are newly
designed. Crankshaft passenger port is filled
with silicone for increased intake efficiency and
two tungsten weights are pressed into the
counterweight for increased torque and mid
speed. Cylinder liner has seven scavenging
ports and three exhaust ports for increased
combustion efficiency. Combustion chamber
and carburetor are newly designed to best
match these parts. Also, better balanced
stronger connecting rod and lighter weight
piston are employed. O.S. standard of easy to
handle characteristics and high performance
have been realized.
