Finding the right replacement bolts for your 1980 Suzuki GS750L's muffler hanger bracket can be surprisingly tricky. This guide will help you navigate the process, ensuring you get the correct hardware and get your bike back on the road. We'll cover everything from identifying the correct bolts to sourcing replacements, addressing common questions along the way.
What Size are the Muffler Hanger Bracket Bolts on a 1980 Suzuki GS750L?
This is the most common question, and unfortunately, there's no single definitive answer without consulting your owner's manual or a Suzuki parts fiche. The size depends on the specific design of your muffler hanger bracket. The best approach is to remove one of the existing bolts (if possible) and take it to your local hardware store or motorcycle parts supplier. They can then match the bolt size, thread pitch, and head type.
This process ensures you get an exact match, avoiding potential issues with fitment and thread stripping. Alternatively, a Suzuki parts fiche (available online or from a dealer) will list the specific part numbers for your model's muffler hanger bracket bolts.
Where Can I Find Replacement Muffler Hanger Bracket Bolts?
Once you know the correct size, finding replacements is relatively easy. You have several options:
-
Local Hardware Stores: Your local hardware store is often the quickest and most convenient option. Take the old bolt as a sample for an exact match. They'll likely stock various metric bolts.
-
Motorcycle Parts Suppliers: Stores specializing in motorcycle parts will carry a wider selection of bolts, potentially including ones specifically designed for motorcycles, which might offer better corrosion resistance.
-
Online Retailers: Numerous online retailers sell motorcycle parts, including bolts. However, be sure to double-check the specifications to ensure compatibility with your 1980 GS750L.
-
Suzuki Dealers: You can also order the bolts directly from a Suzuki dealer. While this is likely the most expensive option, you are guaranteed genuine Suzuki parts.
What Material Should My Replacement Bolts Be Made Of?
For optimal performance and longevity, consider using bolts made of stainless steel. Stainless steel offers superior corrosion resistance compared to standard steel bolts, especially important in an environment exposed to the elements. This will prevent seizing and ensure easier removal during future maintenance.
What if I Can't Find the Exact Bolt Size?
If you can't find an exact match, consider these approaches:
-
Close Match: If a precise match is unavailable, look for a bolt with very similar dimensions. Ensure the thread pitch and diameter are as close as possible. A slightly longer bolt can be used, but a shorter one may be problematic.
-
Bolt Conversion: In some rare cases, you might need to consider a bolt conversion, adapting a different type of bolt to fit. This requires technical expertise and should only be done if you're comfortable working with fasteners. This is generally not recommended for a novice mechanic.
-
Fabrication: As a last resort, you might consider having a custom bolt fabricated. This is usually only necessary for severely damaged or unusual bolts.
Are There Any Specific Considerations for Replacing These Bolts?
-
Torque Specification: Once you have the replacement bolts, ensure you tighten them to the correct torque specification. Using too much force can strip the threads, while insufficient tightening can cause the muffler to become loose. Consult your owner's manual or a service manual for the appropriate torque values.
-
Threadlocker: Applying a small amount of threadlocker (like Loctite) to the bolts before installation can help prevent them from loosening over time due to vibration.
-
Corrosion Protection: Before installation, consider applying a light coat of anti-seize compound to the bolts to further prevent corrosion and make future removal easier.
By following these steps and consulting your owner's manual or a parts fiche, you should be able to successfully replace the muffler hanger bracket bolts on your 1980 Suzuki GS750L. Remember, taking your time and paying attention to detail will ensure a secure and long-lasting repair.
