Estimated 20-24 lb-ft (peak, varies by model year and tuning).
Carburetor:
Keihin PWK 38mm (common for this era and model, specific jetting in manual).
Fuel Type:
Unleaded gasoline, minimum 91 octane (RON + MON)/2.
Premix:
Required 2-stroke oil premixed with gasoline (ratio specified in manual, typically 50:1 or 60:1).
Oil Change:
Gearbox oil: Every 15-20 hours of operation or annually. Premix: As needed for fuel.
Air Filter Cleaning:
Every 5-10 hours of operation, or more frequently in dusty conditions.
Spark Plug Replacement:
Recommended every 20-30 hours, or as needed based on inspection.
Chain Lubrication:
Every 500-750 km, or after riding in wet conditions.
Top End Rebuild:
Recommended every 40-60 hours of hard use, or based on compression loss.

Power Valve Sticking:
Carbon buildup can cause the power valve to stick, affecting engine performance. Requires periodic cleaning.
Clutch Slave Cylinder Leaks:
Hydraulic clutch slave cylinders can develop leaks, affecting clutch operation.
Suspension Seals:
Fork and shock seals can wear over time, leading to oil leaks and reduced damping performance.
Carburetor Jetting:
Requires careful jetting based on altitude, temperature, and exhaust/intake modifications.
