645cc Liquid-cooled DOHC 90-degree V-twin (Fuel Injected)
Petrol
Engage the clutch while in second gear around 4,000rpm to check for clutch slip; if the revs rise without a corresponding increase in speed, it is worth considering the age of the friction plates.
Listen carefully at idle; if you notice a rhythmic 'ticking' from the top end, it is common to investigate whether the valve clearances are nearing their service interval.
Check the front brake lever feel during your ride; if it feels 'spongy', it may suggest that the fluid is due for a flush or the lines have aged, which is quite common for a machine of this generation.
Inspect the rear subframe and the underside of the battery box for signs of corrosion or neglect, as the 'Pointy' SV is often used year-round in NZ weather.
Typically the time for the major valve clearance inspection and spark plug replacement.
A point where suspension linkages may require a thorough clean and re-grease to ensure smooth handling.
Consider having the fuel pump flow rate checked to ensure the injectors are receiving optimal pressure.
Check the coolant levels and the condition of the radiator fins to ensure the engine runs at the correct temperature.
Ensure the drive chain has even tension across its rotation and check the sprocket teeth for 'hooking'.
Verify that the battery terminals are tight and free of any oxidation to prevent starting issues.
Confirm that the throttle cables move freely and return with a satisfying snap to maintain smooth fueling.
Take a look at the tire date codes to ensure the rubber is still supple enough to provide good grip on NZ roads.
Estimated repair costs if issues arise
As the SV650 reaches higher mileage, the valves may settle. This involves a professional workshop adjustment to ensure engine longevity and fuel efficiency.
Depending on the bike's history, you might eventually need to budget for new fork seals and heavier fork oil to restore that sharp handling characteristic of the SV.
If this component needs attention in the future, it is a straightforward job for a mechanic, ensuring your gear shifts remain crisp and positive.
