1130cc Air/Oil-cooled Boxer twin - High performance styling edition
Petrol
Check the braking performance for a 'wooden' feel. | Description: While riding, carefully apply the brakes. If the bike is equipped with the early 'iABS' (Servo-assisted) system, it is common to consider that these units can sometimes become temperamental. Ensure the transition between the servo-assist and manual braking is smooth.
Listen for vibrations and check the clutch engagement point. | Description: During your ride, pay attention to the clutch bite point. In high-mileage examples, you may eventually consider that the dry clutch disc can show signs of wear, particularly if the rear main seal has allowed oil seepage.
Observe the engine's idling stability at operating temperature. | Description: After a thorough warm-up, check the idle. It is worth noting that these Boxer twins benefit from periodic throttle body synchronization; an uneven idle or 'surging' at steady throttle may suggest the bike is due for a tune-up.
Inspect the final drive housing for any signs of fluid weeping. | Description: Before and after your ride, check the final drive pivot point. It is common in bikes of this age to consider that the final drive bearing or seals may require attention to prevent oil from reaching the rear brake rotor.
Usually marks the interval for a comprehensive service, including valve clearance adjustments and a thorough check of the fuel filter located inside the tank.
A common point where technicians recommend inspecting the alternator belt and evaluating the condition of the clutch friction plate.
Consider a full check of the telelever bushings and shock absorbers, as the suspension performance can gradually settle by this stage.
Check engine, gearbox, and final drive oil levels regularly, as these air/oil-cooled motors appreciate fresh fluids.
Keep an eye on the spark plug condition, as the twin-spark models are sensitive to plug fouling.
Maintain a clean air filter to ensure the Boxer engine breathes efficiently during our humid NZ summer.
Ensure the battery is kept on a trickle charger if the bike is sitting, as the electronics can be sensitive to low voltage.
Lubricate the sidestand pivot and check for any play in the handlebars or steering head bearings.
Estimated repair costs if issues arise
If the servo system requires professional repair or replacement, it is worth setting aside funds for this specialized work as it is a complex electronic-hydraulic component.
Since the engine and gearbox must be separated to access the clutch, the labor cost is the primary factor. You might eventually need to budget for this if the clutch begins to slip under load.
Depending on the bike's storage history, you might eventually need to budget for a fuel pump refresh if you experience inconsistent fuel delivery or hard starting.
