Check the gear shift feel by testing a few gear changes through the rev range. | Note: It is worth noting that some second-generation SV650s can experience a notchier gear change if the clutch cable adjustment is neglected or if the shift linkage has worn over time.
While idling, listen closely for any unusual rattling noises coming from the front cylinder area. | Note: On higher mileage examples, it is common to consider the condition of the cam chain tensioners, as they may eventually reach the end of their adjustment range.
Examine the frame and engine casings for any signs of weeping or dried coolant. | Note: These machines are robust, but on units of this age, it is wise to keep an eye on the water pump seals, as they can occasionally show signs of minor wear.
During the test ride, lightly apply the front brake and feel for any pulsing in the lever. | Note: Consistent braking performance is key, and it is common for the front discs to show signs of age or warping if the bike has spent long periods stationary in damp conditions.
Usually involves a major valve clearance check and spark plug replacement.
Often requires a thorough inspection of the suspension linkage bearings and potentially a coolant system flush.
Consider a preventative review of the starter clutch and an assessment of the fork seals.
Check the chain tension and lubrication regularly to ensure smooth power delivery.
Keep an eye on engine oil levels, as the V-twin engine performs best with fresh, high-quality oil.
Periodically inspect the electrical connectors under the seat, as they can sometimes benefit from a clean to ensure solid contact.
Verify the coolant levels in the expansion tank during your routine pre-ride safety checks.
Ensure the air filter is kept clean to allow the fuel injection system to operate as efficiently as possible.
Estimated repair costs if issues arise
If the charging system shows signs of weakness in the future, it is common to replace the stator and regulator/rectifier to ensure reliable starts. Depending on the bike's history, you might eventually need to budget for this repair.
If the front forks feel a bit soft or bouncy, it is a great opportunity to consider a fork oil change or seal replacement. If this component needs attention in the future, the estimated cost in NZ is usually manageable.
