Cylinder Hone Selection And Honing Procedure - Polaris Sportsman 800 EFI 4x4 2012 Service Manual

ENGINE
13. Start engine and observe coolant level in the
radiator. Allow air to purge and top off as necessary.
Reinstall radiator cap and bring engine to operating
temperature. After engine is cool, check level in
reservoir tank and add coolant if necessary.
NOTE: Should the reservoir tank become empty,
it will be necessary to refill at the radiator and
repeat the bleeding procedure.
Engine Break-In Period
The break-in period for a Polaris ATV engine is
defined as the first ten hours of operation, or the time
it takes to use two full tanks of gasoline. No single
action on your part is as important as a proper break-
in period. Careful treatment of a new engine will
result in more efficient performance and longer life
for the engine. Perform the following procedures
carefully.
Use only Polaris PS4 2W/50 synthetic oil or equivalent.
Never substitute or mix oil brands. Serious engine
damage and voiding of warranty can result.
Do not operate at full throttle or high speeds for
extended periods during the first three hours of use.
Excessive heat can build up and cause damage to
close fitted engine parts.
14. Fill fuel tank with unleaded or leaded fuel which has
a minimum pump octane number of 87= (R+ M)/2.
15. Check oil reservoir level indicated on dipstick. Add oil
if necessary (Refer to Chapter 2, "Engine Oil Level" ).
16. Drive slowly at first to gradually bring engine up to
operating temperature.
17. Vary throttle positions. Do not operate at sustained
idle or sustained high speed.
18. Perform regular checks on fluid levels, controls and
all important bolt torques. Pull only light loads during
initial break in.
19. Pull only light loads during initial break-in.
20. Change break in oil and filter at 20 hours or 200
miles.

Cylinder Hone Selection And Honing
Procedure
A hone which will straighten as well as remove material
from the cylinder is very important. Using a common
spring loaded glaze breaker for honing is not advised
for nicasil cylinders.
Polaris recommends using a rigid hone or arbor honing
machine. Cylinders may be wet or dry honed depending
upon the hone manufacturer's recommendations.
Wet honing removes more material faster and leaves a
more distinct pattern in the bore.
