Type:
Two-stroke, single-cylinder
Displacement:
246cc (approximate, may vary slightly by year)
Bore X Stroke:
Typically around 66.0 mm x 72.0 mm (refer to manual for exact figures)
Cooling System:
Air-cooled
Reed Valve System:
Yes (standard for performance two-strokes of this era)
Horsepower Estimate:
Approximately 25-30 HP (at crankshaft, refer to manual for precise figures)
Torque Estimate:
Refer to manual for specific torque figures.
Carburetor Type:
Mikuni VM Series (e.g., VM34SS or similar)
Carburetor Size:
Typically 34mm (refer to manual for exact model and jetting)
Fuel Type:
Unleaded gasoline mixed with two-stroke oil (specified ratio in manual)
Type:
CDI (Capacitor Discharge Ignition) with breaker points and mechanical advance (typical for the era)
Oil Change Engine:
Two-stroke engines do not have a separate oil sump for crankcase lubrication; oil is mixed with fuel. Transmission oil change interval: refer to manual, typically every 3,000-5,000 km or annually.
Spark Plug Replacement:
Refer to manual; typically every 1,000-2,000 km or as needed based on performance.
Air Filter Cleaning:
Frequent cleaning recommended, especially for off-road use (e.g., every few rides or after dusty conditions). Refer to manual for specific procedure.
Two Stroke Oil Mix:
Suzuki recommends a specific ratio (e.g., 20:1 or 30:1, check manual) of high-quality two-stroke oil.
Transmission Oil Viscosity:
SAE 80W or SAE 90 gear oil (verify in manual).
Engine:
Wear on piston rings and cylinder bore due to hard use, carburetor jetting sensitivity, clutch wear, potential for crank seal leaks.
Suspension:
Fork seal leaks, rear shock absorber wear and fluid degradation. Chain and sprockets are wear items.
Electrical:
Points wear, coil failure, aging wiring can lead to intermittent issues.
Carburetor Cleaning And Jetting:
Detailed instructions for disassembly, cleaning jets, float bowl, and adjusting air/fuel mixture and idle speed are crucial.
Top End Rebuild:
The manual will guide through piston, ring, and cylinder replacement, including ring gap and piston-to-cylinder clearance checks.
Ignition Timing Adjustment:
Critical for performance and reliability, the manual will detail how to set points gap and ignition timing using a timing light or feeler gauge.
Company Focus:
Suzuki has a long history in motorcycle manufacturing, known for its sporty and innovative designs across various segments.
Pe Series Context:
The PE series was Suzuki's dedicated line of motocross and cross-country motorcycles, evolving from earlier models and leading to later RM (motocross) and DR (dual-sport) platforms.
Production Period:
The PE250 was produced throughout the late 1970s and early 1980s, with significant updates occurring during this period.
