Do i adjust valves on a 650 v strom – Do I adjust valves on a 650 V-Strom? This question often arises for Suzuki V-Strom 650 owners, and it’s a crucial one for ensuring optimal performance and longevity of your motorcycle. The valve train, a complex system of components like camshafts, rocker arms, and valves, plays a vital role in regulating the flow of air and fuel into the engine.
Regular valve adjustments ensure proper engine operation, preventing issues like decreased power, rough idling, and even potential engine damage.
Understanding the signs that indicate a need for valve adjustment is essential. Listen for unusual engine noises, check for rough idling, and pay attention to any noticeable decrease in power. Suzuki provides specific valve adjustment intervals for the 650 V-Strom, and adhering to these recommendations is key to maintaining peak engine health. Armed with the right tools and knowledge, you can confidently check valve clearances and perform adjustments yourself, ensuring your V-Strom runs smoothly and efficiently.
Valve Adjustment Basics
Valve adjustments are crucial for maintaining optimal engine performance in your Suzuki 650 V-Strom. Proper valve clearance ensures the engine operates efficiently and reliably, preventing premature wear and tear.
Valve Train System in the 650 V-Strom
The valve train system in a 650 V-Strom comprises several key components that work together to control the flow of air and exhaust gases into and out of the engine cylinders.
- Camshafts: These rotating shafts, driven by the engine’s crankshaft, control the opening and closing of the valves. Each camshaft has a series of lobes that interact with the rocker arms, timing the valve operation.
- Rocker Arms: These lever-like components are actuated by the camshaft lobes and transfer motion to the valves.
- Valves: The intake and exhaust valves are responsible for controlling the flow of air and exhaust gases in and out of the combustion chamber.
- Valve Clearances: These are the small gaps between the rocker arms and the valves when the valve is closed. The clearance ensures that the valves are not held open when they should be closed, preventing damage and ensuring proper valve operation.
Consequences of Neglecting Valve Adjustments
Failing to adjust valves at recommended intervals can lead to various issues that negatively impact your engine’s performance and longevity.
- Decreased Power: Improper valve clearance can hinder the flow of air and exhaust gases, leading to a reduction in engine power and torque.
- Rough Idling: When valve clearances are too tight, the valves may not close completely, causing a rough idle and potentially leading to misfires.
- Engine Damage: Excessive valve clearance can result in the valves hitting the piston, causing catastrophic engine damage.
Determining the Need for Adjustment
Valve clearance is a critical aspect of engine performance. Over time, the valve components wear, causing the clearance to change. When the valve clearance is too tight or too loose, it can lead to a variety of problems, including decreased engine performance, increased fuel consumption, and even engine damage.
Valve Clearance Specifications
Suzuki provides specific valve clearance specifications for the 650 V-Strom. These specifications are critical for ensuring proper engine operation. The valve clearance should be checked at regular intervals, as recommended by Suzuki, to ensure that it remains within the specified range.
The recommended valve adjustment interval for the Suzuki 650 V-Strom is every 12,000 miles (19,312 kilometers). However, it’s advisable to check the valve clearance sooner if you notice any of the common signs of valve clearance issues.
Common Signs of Valve Clearance Issues
Here are some common signs that may indicate a need for valve adjustment on your 650 V-Strom:
- Rough idle: A rough idle can be a sign that the valves are not opening and closing properly. This can be caused by excessive valve clearance.
- Loss of power: If your engine is losing power, it could be a sign that the valves are not opening fully. This can be caused by insufficient valve clearance.
- Increased fuel consumption: If your engine is burning more fuel than usual, it could be a sign that the valves are not sealing properly. This can be caused by excessive valve clearance.
- Unusual noises: If you hear any unusual noises coming from your engine, such as tapping or clicking, it could be a sign that the valves are not operating correctly. This can be caused by either excessive or insufficient valve clearance.
Checking Valve Clearance
To check the valve clearance, you will need the following tools:
- Feeler gauges: These are thin metal blades of varying thicknesses used to measure the gap between the valve stem and the rocker arm.
- Torque wrench: This is a specialized wrench used to tighten bolts and nuts to a specific torque value.
- Valve adjustment shims: These are thin metal washers used to adjust the valve clearance.
- Service manual: This provides detailed instructions on how to adjust the valves on your specific model.
Here are the general steps involved in checking valve clearance:
- Remove the valve cover: Locate the valve cover on your engine and remove it using the appropriate tools.
- Rotate the engine: Rotate the crankshaft until the camshaft lobes for the valve you want to check are in the correct position. Consult your service manual for specific timing marks.
- Insert the feeler gauge: Carefully insert the feeler gauge between the valve stem and the rocker arm. Select the feeler gauge that fits snugly but can be moved with a slight amount of resistance.
- Measure the clearance: The thickness of the feeler gauge that fits snugly represents the valve clearance. Compare this measurement to the specifications in your service manual.
- Adjust the clearance: If the valve clearance is outside the specified range, you will need to adjust it using shims. Consult your service manual for instructions on how to do this.
- Reinstall the valve cover: Once you have adjusted the valve clearance, reinstall the valve cover and torque the bolts to the specified value.
Valve Adjustment Procedure
Valve adjustment is a critical maintenance task for any motorcycle engine, including the Suzuki 650 V-Strom. This procedure ensures optimal engine performance and longevity by maintaining the correct clearance between the valve and the camshaft.
Valve Adjustment Tools and Safety Precautions
Before starting the valve adjustment procedure, gather the necessary tools and take appropriate safety precautions.
- Tools: You will need a set of feeler gauges, a torque wrench, a 10mm wrench, a 12mm wrench, a 14mm wrench, and a socket wrench.
- Safety Precautions:
- Wear safety glasses to protect your eyes from flying debris.
- Work in a well-ventilated area.
- Ensure the motorcycle is stable and secure on a stand.
- Disconnect the battery to prevent electrical shock.
Valve Clearance Specifications
The following table lists the recommended valve clearances for the Suzuki 650 V-Strom:
| Cylinder | Valve | Clearance (mm) |
|---|---|---|
| Front | Intake | 0.10 – 0.15 |
| Front | Exhaust | 0.15 – 0.20 |
| Rear | Intake | 0.10 – 0.15 |
| Rear | Exhaust | 0.15 – 0.20 |
Valve Adjustment Steps
- Remove the fuel tank and airbox. This will give you access to the valve cover.
- Remove the valve cover. This is typically secured by several bolts.
- Locate the camshaft lobes for the valve you are adjusting. The intake camshaft lobe is smaller than the exhaust camshaft lobe.
- Rotate the engine until the valve is fully closed. This is achieved when the camshaft lobe is at its highest point.
- Insert a feeler gauge between the valve stem and the camshaft lobe. Use the appropriate feeler gauge to check the valve clearance.
- Adjust the valve clearance by loosening or tightening the adjusting nut. The adjusting nut is located on the rocker arm.
- Tighten the adjusting nut to the specified torque. This torque value can be found in your motorcycle’s service manual.
- Repeat steps 5-7 for all valves. Ensure all valves are adjusted to the correct clearance.
- Reinstall the valve cover. Make sure to tighten the bolts to the specified torque.
- Reinstall the airbox and fuel tank.
- Start the engine and check for any unusual noises. If you hear any clicking or tapping sounds, recheck the valve clearances.
Tightening and Loosening Adjusting Nuts
- Tightening: To tighten the adjusting nut, use a wrench to turn it clockwise. As you tighten the nut, the valve clearance will decrease.
- Loosening: To loosen the adjusting nut, use a wrench to turn it counterclockwise. As you loosen the nut, the valve clearance will increase.
Adjusting Valve Clearance
- If the valve clearance is too tight: Loosen the adjusting nut until the correct clearance is achieved.
- If the valve clearance is too loose: Tighten the adjusting nut until the correct clearance is achieved.
