1130cc Air/Oil-cooled Boxer Twin
Petrol
During the ride, perform a few deliberate shifts to check the clutch engagement. In models of this age, it is common to consider the condition of the dry clutch plate, which can be labour-intensive to access if it shows signs of slipping.
Before heading out, squeeze the front brake lever while stationery and check the operation of the servo-assisted ABS system if fitted. These units can occasionally become temperamental as they age, so listen for the characteristic pump whir and ensure no warning lights persist.
While idling in neutral, listen closely to the cylinder heads for any excessive tapping. The valve train on these boxer twins is robust, but it is wise to confirm that regular adjustments have been carried out to maintain smooth operation.
Inspect the final drive housing for any signs of fluid weeping. Given the age of these machines, it is worth keeping an eye on the seals and bearings to ensure the shaft drive remains in good order over time.
Usually marks the point for a major service including valve clearances and fluid flushes.
Often the time to inspect the alternator belt and ensure the swingarm pivot bearings are greased.
Consider a full check of the fuel system components and potential inspection of the clutch friction disc thickness.
Ensure regular engine oil and filter changes are documented to keep the air/oil-cooled boxer running at its best.
Check the condition of the brake lines, specifically looking for any signs of fatigue or seepage.
Keep up with the throttle body synchronization to maintain that signature smooth, low-end torque.
Periodically inspect the rubber intake manifolds for any fine cracks that might cause a lean running condition.
Verify the battery health frequently, as these bikes can be sensitive to voltage drops during cold starts.
Estimated repair costs if issues arise
If the ABS system requires servicing in the future, it is a complex job involving the hydraulic pump unit. Depending on the repair shop's approach, you might eventually need to budget for professional testing or specialist refurbishments.
Because the clutch is a dry-plate design buried between the engine and gearbox, the labour involved is significant. If this needs attention in the future, it is common to plan for a substantial workshop visit.
If the rear main seal shows signs of wear, it is a manageable job but requires precision. It is wise to set aside a little extra in your future budget planning to ensure the shaft drive remains leak-free.
