1986 Intruder Gears Won't Engage: Possible Causes

If you own a 1986 Intruder motorcycle and are experiencing trouble with the gears not engaging properly, it can be frustrating and hinder your riding experience. There are several potential causes for this issue, and in this article, we will explore some of the common culprits to help you identify and resolve the problem.

1. Clutch Problems

A malfunctioning clutch is often a leading cause of gear engagement issues. If your clutch isn't working correctly, the gears may not fully disengage or engage, resulting in difficulty shifting. There are a few aspects of the clutch system that may require attention:

• Clutch Lever Adjustment: Ensure that the clutch lever has the proper amount of free play. If the lever is too loose or too tight, it can affect the clutch engagement, leading to gear problems.
• Clutch Cable Issues: Inspect the clutch cable for any signs of damage or excessive wear. A broken or improperly adjusted clutch cable can prevent the necessary movement for smooth gear shifting.
• Clutch Plates: Worn or damaged clutch plates can cause slippage or incomplete engagement, making it difficult for the gears to engage properly. If the clutch plates show signs of wear or deterioration, they may need to be replaced.

2. Transmission Troubles

Issues within the transmission can also lead to gear engagement problems. Mechanical parts wear down over time, and the transmission is no exception. Here are some aspects to consider:

• Gear Teeth Wear: Over time, the gear teeth can start to wear down, making it difficult for them to engage smoothly. If the teeth show signs of significant wear, repairing or replacing the affected gears may be necessary.
• Shift Fork Damage: The shift forks are responsible for moving the gears into their proper positions. If the shift forks are bent, damaged, or worn, they may not be able to engage the gears correctly. Inspect the shift forks for any signs of damage and replace if necessary.
• Transmission Oil Level and Quality: Low or contaminated transmission oil can also hinder gear engagement. Ensure that the oil level is correct and that the fluid is not dirty or degraded. Regularly changing the transmission oil is crucial to maintaining optimal performance.

3. Other Factors

While clutch and transmission problems are often the main culprits, there are a few additional factors that could be causing gear engagement issues:

• Shifter Mechanism: The shifter mechanism, including the shift lever and linkage, should be inspected for any damage or misalignment. Any issues with the shifter mechanism can affect the gear engagement process.
• Engine RPM: If the engine RPM is too high or too low while shifting gears, it can make engagement difficult. Make sure to shift gears at appropriate RPM levels to avoid any problems.
• Worn Clutch Basket: A worn clutch basket can result in clutch drag, preventing the gears from fully engaging. Inspect the clutch basket and replace if necessary.

It is important to note that diagnosing and repairing gear engagement issues can vary in complexity. If you are unsure or lack the expertise, it is recommended to consult a professional motorcycle mechanic for a thorough inspection and accurate diagnosis of the problem.

By addressing the potential causes mentioned above, you can increase your chances of resolving the gear engagement problem with your 1986 Intruder motorcycle. Ensure regular maintenance, proper adjustments, and timely repairs to enjoy a smooth and trouble-free riding experience.
