Can-Am DS 70 / DS 90 / DS 90X ATV Operator’s Guide, 2009 (P/N 219 000 629)

The 2009 Can-Am DS 70, DS 90 and DS 90X Operator’s Guide (P/N 219 000 629) covers category Y youth ATVs, with operating instructions, basic maintenance and owner-level troubleshooting. Its scope is everyday operation and upkeep; internal CVT repair and carburetor adjustment are referred to an authorized dealer.

Chapter Search and PDF Bookmarks

Text search and section access: The main chapters have searchable text, and embedded PDF bookmarks provide access to operating instructions, maintenance, specifications and troubleshooting. Cover text and some illustrated labels and forms are not reliably searchable.

One printable, English-language 133-page PDF contains 128 numbered pages plus five unnumbered pages: the front and back covers, a safety/copyright page, a vehicle-information record and one nearly blank page. All are included in the total.

Youth ATV Operation and Routine Maintenance

The following selected topics outline the guide’s coverage rather than reproduce its complete contents. Other subjects include vehicle transportation and post-ride care.

• Controls and operation: Pre-ride inspection, starting and stopping, speed-limiter adjustment, transmission positions and model-specific suspension preload adjustment.

• Engine and intake maintenance: Step-by-step instructions for engine oil changes, strainer cleaning, air-filter service, air-box draining and air-injection valve filter cleaning.

• CVT and final drive: CVT-cover draining, gearbox oil replacement, drive-chain cleaning and adjustment, and sprocket and chain-roller inspection.

• Brakes and chassis: Mechanical brake-cable adjustment for DS 70/DS 90, hydraulic brake checks for DS 90X, wheel removal and front-knuckle lubrication.

• Basic electrical service: Spark plug and battery removal and installation, fuse replacement, and daytime-running-light bulb replacement for DS 70/DS 90.

• Troubleshooting: Symptom-based guidance for starting problems, power loss, backfiring, misfiring, overheating and loss of drive, with referrals for dealer-level diagnosis.

Written for owners/operators and adults supervising young riders, the guide limits its basic maintenance procedures to adults with the necessary mechanical skills and tools.

Maintenance Planning and Drivetrain Limits

The periodic maintenance chart separates customer tasks from dealer work and identifies the initial inspection after 10 hours or 30 days, whichever comes first. This distinction helps an adult owner plan routine upkeep and recognize work requiring additional skills or equipment.

CVT and carburetor: Drive-belt and pulley inspections appear as dealer maintenance items. The guide provides CVT-housing drainage instructions, but no belt-replacement or pulley-overhaul procedure. It explains the PTE carburetor’s manual choke for starting; carburetor adjustment is assigned to a dealer.

Intake, exhaust and chain care: Air-injection-valve filter cleaning and spark-arrester cleaning have illustrated procedures. The chain section warns that replacing only part of the chain, axle-sprocket and pinion set can cause rapid chain and sprocket wear.

Brake and Suspension Differences

Model-specific brakes: DS 70 and DS 90 use mechanical drum brakes, while DS 90X uses hydraulic disc brakes. The guide distinguishes cable adjustments from hydraulic fluid-level and pad checks; brake-system repairs and brake-fluid replacement are assigned to an authorized Can-Am dealer.

Suspension and control illustrations: Front and rear preload views distinguish the adjusting cams on DS 70/DS 90 from the locking and adjustment rings on DS 90X. The transmission-lever pattern, oil-viscosity chart and throttle free-play illustration provide further references for routine setup.

The speed-limiter section warns that incorrect adjustment can damage the throttle cable and impair throttle-lever operation.

Starting Problems and Electrical Checks

The troubleshooting section distinguishes an engine that will not crank from one that cranks without starting. Its checks address switches, the main fuse, battery connections, fuel supply and spark-plug condition before directing more involved faults to a dealer.

Electrical coverage consists of basic component checks and replacement guidance; wiring diagrams are not included. Follow the factory safety guidance, including fuel-handling precautions and carbon-monoxide warnings, before beginning maintenance or diagnostic work.

Examples of Throttle and Chain Adjustment Data

For all three models, normal throttle-lever free play is 5–10 mm (3/16–13/32 in), measured at the lever tip.

Drive-chain free play is specified as 44–57 mm (1-3/4–2-1/4 in) of vertical movement, checked with the vehicle unloaded and no rider seated. The accompanying slack drawing illustrates the measurement.
