H1: Fix That Leak! 1980 GS750 Exhaust Collar Upgrade

Introduction:

The 1980 Suzuki GS750, a classic motorcycle known for its reliability and smooth power delivery, can unfortunately suffer from a common issue: exhaust leaks at the exhaust collar. This annoying problem results in lost power, a sputtering engine, and that tell-tale rasping sound. This guide will walk you through upgrading your exhaust collar for a permanent solution. We'll focus on replacing the stock collar with a more robust and reliable alternative, permanently silencing those pesky leaks.

H2: Identifying the Problem: Why Your GS750 Exhaust Leaks

The exhaust collar on the 1980 GS750 is a crucial component. It seals the connection between the exhaust header pipes and the muffler. Over time, the original collar can corrode, warp, or simply wear out, leading to exhaust leaks. This is often exacerbated by heat cycling and vibrations from the engine. The symptoms are clear: a noticeable exhaust leak sound, reduced power, and possibly even a failed emissions test.

H2: Gathering Your Tools and Parts

Before you begin, gather the necessary tools and parts. This upgrade will require:

• New Exhaust Collar: Research aftermarket replacements designed for the 1980 GS750. Look for high-quality stainless steel options for superior durability. (Include links to reputable online retailers if possible.)
• Wrench Set: You'll need various wrenches to remove and install the exhaust system components.
• Socket Set: This will provide the right tools for specific bolts.
• Screwdrivers: Possibly Phillips and flathead, depending on the specific fasteners.
• Penetrating Oil (e.g., PB Blaster): This helps loosen rusted or stubborn bolts.
• Gloves and Safety Glasses: Always protect yourself when working on your motorcycle.
• Jack and Stand: Securely support your motorcycle to prevent accidents.
• High-Temperature RTV Silicone: To create an additional seal (optional but recommended).

H2: Step-by-Step Exhaust Collar Replacement

(Include detailed steps with accompanying images or diagrams. Each step should be a short paragraph, approximately 2-3 sentences.)

1. Secure the Motorcycle: Use a jack and stand to safely lift and secure your GS750. Ensure stability before proceeding.

2. Remove the Exhaust System: Carefully disconnect the exhaust system, starting from the muffler and working your way towards the engine. Use penetrating oil to loosen any stubborn bolts if necessary.

3. Inspect the Old Collar: Examine the old exhaust collar for signs of damage, corrosion, or wear. This will help you understand why the leak occurred.

4. Install the New Collar: Carefully slide the new exhaust collar into place, ensuring proper alignment with the exhaust header pipes and muffler.

5. Tighten the Bolts: Securely tighten all bolts, using a torque wrench if possible to avoid over-tightening. Consult your motorcycle's service manual for proper torque specifications.

6. Apply RTV Silicone (Optional): A bead of high-temperature RTV silicone around the collar can provide an extra layer of sealing protection. Allow the silicone to cure completely before restarting the engine.

7. Reconnect the Exhaust System: Carefully reconnect the exhaust system, ensuring all components are properly aligned.

H2: Post-Upgrade Checks

After completing the installation, check for any leaks. Start the engine and listen carefully for any telltale sounds. Inspect the collar area for signs of exhaust fumes. If everything is tight and sealed, you've successfully fixed the exhaust leak.

H2: Troubleshooting Common Issues

• Bolts won't loosen: Apply more penetrating oil and allow it to sit for several hours. Consider using heat to help loosen the bolts.
• New collar doesn't fit: Double-check that you ordered the correct collar for your 1980 GS750. Contact the supplier if needed.
• Persistent Leak: Inspect the collar for proper seating. Ensure the bolts are properly tightened to specification. Consider using additional high-temperature RTV sealant.

Conclusion:

Upgrading your 1980 GS750's exhaust collar is a relatively straightforward repair that can significantly improve your motorcycle's performance and sound. By following these steps and utilizing high-quality parts, you can eliminate those annoying exhaust leaks and enjoy a smoother, more powerful ride. Remember safety first – always wear appropriate safety gear when working on your motorcycle. This upgrade should restore your classic GS750 to its former glory!
