OPERATION

Engine Break-In

No single action on your part is as important to long, trouble-free

machine life as proper break-in of a new or rebuilt engine. Premix the

first 3.5 gallons (13.2 l) of gasoline with 16 oz. (473 ml) of the

recommended 2-cycle racing oil (28:1). Premix future gasoline at 32:1.

CAUTION

Excessive heat build-up during the first three hours of operation

will damage close-fitted engine parts. Do not operate at full

throttle or high speeds for extended periods during the first three

hours of use. Vary the throttle openings and machine speeds to

reduce friction on all close-fitting machined parts, allowing them

to break in slowly without damage.
Use of any lubricants other than those recommended by Polaris

may cause serious engine damage. We recommend the use of

Polaris lubricants for your vehicle.
Drive with extra caution during the break-in period. Perform

regular checks on fluid levels, lines, and all other important areas

of the machine.
