Kx85 Horsepower Approx:
Estimated 20-25 HP (specific figures vary by year and tuning).
Kx100 Horsepower Approx:
Estimated 25-30 HP (specific figures vary by year and tuning).
Carburetor Type:
Typically a Keihin PWK carburetor (e.g., PWK28 for KX85, PWK33 for KX100, specific sizes may vary).
Fuel Type:
Unleaded gasoline, requires 2-stroke oil pre-mix or injection (depending on specific model variation within the year range).
Premix Ratio:
Typically 50:1 or 40:1 (check manual for exact specification).
Air Filter Cleaning:
Recommended after every few rides, or more frequently in dusty conditions.
Transmission Oil Change:
Recommended every 10-15 hours of riding or annually. Specific fluid type is critical.
Spark Plug Replacement:
As needed based on condition, but generally inspected every 10-20 hours of riding.
Chain Lubrication Adjustment:
Regularly before and after rides, and adjustment as per manual specifications.
Transmission Oil:
Kawasaki specifies specific transmission oil (e.g., SAE 10W-30 API SG or SH). Refer to the manual for exact part number and viscosity.
Coolant Type:
Typically a 50/50 mixture of ethylene glycol-based antifreeze and distilled water. Refer to manual for specific type and capacity.
Brake Fluid:
DOT 3 or DOT 4 hydraulic brake fluid. Always use fresh, sealed fluid.
Piston Wear:
Common for 2-stroke engines; regular piston and ring inspection and replacement based on hours or performance degradation is crucial.
Clutch Slippage:
Can occur with aggressive riding or worn plates; clutch maintenance and adjustment are key.
Fork Seal Leaks:
Typical wear item for front suspension; requires periodic inspection and replacement.
Kips System Carbon Buildup:
Periodic cleaning of the KIPS valve system is recommended to maintain optimal power delivery and prevent sticking.
