Factory Technical Data
The 1998 Yamaha YFM250XL(C) service manual delivers specialized technical data essential for maintaining and overhauling the Bear Tracker 250. It maps out exact inspection and adjustment sequences for the air-cooled 4-stroke engine. You get direct access to factory valve clearance parameters, timing chain tensioner inspection steps, and compression pressure limits. Moving to the drivetrain, the documentation breaks down the constant mesh 5-speed transmission, shift mechanisms, and crucial gear lash measurements for both middle and final drive gears.
Because ATV maintenance involves significant mechanical risk, always adhere to strict workshop safety practices when referencing this data. Ensure you possess the appropriate mechanical background or consult a certified technician before executing major engine or chassis work.
The chassis section defines suspension maintenance for the strut-based front setup and monocross swingarm rear. It documents tire pressure specifications for the OEM Carlisle and Dunlop Trail Wolf tires, alongside brake lining inspection limits for the drum brake systems. For electrical diagnostics, the manual provides circuit diagrams and troubleshooting paths for the C.D.I. ignition system, A.C. magneto charging system, and starting circuit.
Specification Highlights
This literature lists 900 kPa as the standard engine compression pressure for the YFM250XL(C). Intake valve clearance sits at 0.05–0.09 mm. When servicing the drivetrain, the final drive gear oil capacity requires a specific 0.25-liter fill. You will also find tightening torques for all primary assemblies, including the vital 50 Nm setting for the balancer drive gear nut.
