Exhaust System; Drive Chain Tension - Polaris Trail RMK Owner's Manual

MAINTENANCE

Exhaust System

Check the exhaust system for wear or damage at approximately 1000
miles (1600 km). To inspect, allow the engine and exhaust system to
cool completely. Open the hood and inspect the muffler and pipes for
cracks or damage. Check for weak or missing retaining springs or
damper/support grommets.
CAUTION! Hot exhaust system parts can cause burns. Allow adequate time for
the exhaust system to cool. Never perform this procedure with the engine
running.

Drive Chain Tension

To obtain correct chain tension:
1. Rotate the driven clutch coun-
terclockwise to move all chain
slack to the tensioner side.
Lock the brake lever lock, or
have an assistant hold the
brake lever firmly.
2. Loosen the adjuster bolt jam
nut.
3. Finger tighten the adjuster
bolt until it can no longer be
adjusted by hand, then back
off 1/4 turn.
4. Tighten the jam nut while
holding the adjuster bolt.
5. The chain is now tensioned.
Release the brake lever lock.
