The Honda Gold Wing series has long been synonymous with comfortable, long-distance touring, and the GL1100, the second-generation iteration, holds a special place in the hearts of classic motorcycle enthusiasts. Building upon the foundational success of the GL1000, the GL1100 introduced significant refinements and cemented the Gold Wing's reputation as the ultimate touring machine. For owners and prospective buyers alike, understanding where these magnificent machines were born and how to address their common quirks is crucial for keeping them purring for decades to come. This article delves into the GL1100's manufacturing journey and provides invaluable insights into troubleshooting and rectifying typical issues, ensuring your classic Gold Wing continues to deliver miles of joy.
The Gold Standard's Genesis: Where the GL1100 Was Born
Following a successful five-year run for the groundbreaking GL1000, Honda unveiled its successor, the GL1100, in 1979 as a 1980 model. This new iteration brought a host of improvements, enhancing its capabilities as a grand touring motorcycle. Initially, production of the GL1100 models, particularly for the 1980 model year, commenced in Japan, as was customary for Honda's high-quality motorcycles.
However, a significant shift occurred in May 1980. Recognising the burgeoning demand and the strategic importance of the North American market, Honda made a pivotal decision: to begin manufacturing the GL1100 on American soil. From this point onwards, the 1981, 1982, and 1983 model year GL1100s were proudly built at the state-of-the-art Marysville Motorcycle Plant in Ohio, USA. This move was a testament to Honda's commitment to local production and solidified the Gold Wing's status as a truly international machine.
Understanding the GL1100's production timeline is key:
| Model Year | Manufacturing Location | Notes |
|---|---|---|
| 1980 | Japan | Initial production run, maintaining Japanese quality standards. |
| 1981 | Marysville, Ohio, USA | First full year of US production, a landmark for Honda. |
| 1982 | Marysville, Ohio, USA | Continued US production, refining processes. |
| 1983 | Marysville, Ohio, USA | Final year of GL1100 production before the GL1200's introduction. |
This dual-location heritage adds an interesting layer to the GL1100's story, showcasing Honda's global manufacturing prowess and their strategic approach to market demands. Regardless of its specific birthplace, every GL1100 was engineered with the robust reliability and touring comfort that Gold Wing owners have come to expect.
While renowned for their durability, classic motorcycles like the GL1100 can develop specific age-related issues. Fortunately, many of these common problems have well-documented, practical solutions, often shared by seasoned experts like Howard Halasz, a noted GL1100 guru and frequent technical contributor to GWRRA’s Wing World Magazine. Tackling these issues proactively can significantly extend the life and enjoyment of your Gold Wing.
The Elusive Vacuum Advance (Pulse Generator Assembly)
One of the most frequently encountered failures with all GL1100s involves the vacuum advance part of the pulse generator assembly. It's important to note that the units for the 1980 models utilise a higher advance angle compared to those found on the 1981-1983 models. Unfortunately, the vacuum portion of this crucial assembly is not rebuildable, and genuine Honda GL1100 pulse generators are no longer available from the manufacturer. Good used units have also become increasingly difficult to source.
However, there's a remarkably simple and effective workaround that veteran mechanics swear by. The solution is to simply plug the vacuum fitting at the number three carburettor. The loss of this vacuum advance will, in most riding conditions, be virtually unnoticeable to the rider, with only a very slight decrease in fuel economy and negligible performance loss. This straightforward modification allows owners to bypass a common failure point without compromising the bike's overall rideability or enjoyment.
The "Tar-Like Substance" and Transistor Spark Units
Another tell-tale sign of an impending electrical issue on your GL1100 is the appearance of a tar-like substance on the frame directly below the transistor spark units. This substance is typically the potting compound used within the units melting out, indicating that the units are either about to fail or have already begun to do so. Ignoring this symptom can lead to frustrating breakdowns.
To prolong the life of these essential transistor spark units, a clever repair method involves a bit of DIY. First, carefully disconnect and remove the units from the frame. Prepare some 5-minute epoxy glue and meticulously fill the areas where the tar has melted out. Ensure the epoxy glue is thoroughly mixed and applied, then allow it to set completely until it is fully cured. Once hardened, the units can be safely reinstalled. This simple repair can often significantly extend the operational life of these otherwise problematic components, saving considerable expense and hassle.
Flickering Flasher Fails: The Turn Signal Saga
A peculiar weakness, particularly prevalent in the 1983 GL1100 models, is the early failure of the turn signal flasher unit. While the 1980-1982 models rarely experienced these issues, they were quite common with the '83s. This specific vulnerability in the final GL1100 production year can be attributed to a unique electronic Honda flasher used exclusively on the '83 models, which featured a black 3-pin connector rather than the standard 2-blade flasher connectors found on all other GL1100s.
Thankfully, the fix is both cheaper and more effective than sourcing a potentially unreliable Honda OEM replacement. Owners can simply use a standard automotive flasher. This readily available and inexpensive component can be connected to the grey wire and black wire of the turn signal circuit, resolving the problem reliably. This is a classic example of how a widely available, generic part can often outperform a specific, hard-to-find OEM component in the world of vintage motorcycle maintenance.
Beyond the Fixes: Maintaining Your Classic Gold Wing
While addressing specific ailments is important, the longevity of any classic motorcycle, including the GL1100, hinges on diligent general maintenance. Owners should make it a routine to check and replace consumables and wear items. Reputable parts suppliers, such as Old Bike Barn, offer a comprehensive selection of Honda GL1100 parts specifically designed to keep these magnificent machines on the road. This includes essential items such as engine gasket sets, carburettor kits for proper fuel delivery, fork seals to prevent leaks and ensure smooth suspension, new levers, fresh control cables for precise operation, and brake pads for optimal stopping power.
Beyond specific parts, consistent fluid checks (engine oil, brake fluid, coolant), regular tyre pressure monitoring, and general lubrication are paramount. Investing in a good workshop manual, such as Howard Halasz's Carburettor Repair Manual, can empower owners with the knowledge to perform many maintenance tasks themselves. Furthermore, engaging with the Gold Wing community can provide invaluable peer support and access to shared wisdom. Whether you're aiming for a pristine restoration or considering a custom project like a Cafe Racer, Street Tracker, Brat, or Chopper, the underlying principle remains: regular, informed maintenance is the bedrock of a reliable and enjoyable classic motorcycle experience.
