Common Issues and Solutions

Let’s deep dive into the common issues and solutions regarding the engines and the Harley 107 vs 114 reliability:

Milwaukee-Eight 107 Issues

Similar to many engines, the Milwaukee-Eight 107 is not without its challenges. Some of the common issues experienced by Harley Davidson owners include:

  • Inadequate Cam Chain Tensioners: The cam chain tensioners in the 107 engine may wear out after prolonged use, leading to inadequate tension and possible engine damage. To address this, regular maintenance and inspection are advised. Replacing worn tensioners with upgraded parts can help improve the engine’s longevity.
  •  Heating Issues: Due to its increased displacement, the Milwaukee-Eight 107 engine may generate more heat than previous models. To mitigate this, one can invest in heat management solutions like heat shields, cooling fans, and oil coolers.
  •  OEM Lifter Issues: The original lifters on 107 engines can exhibit wear or perform inconsistently, leading to reduced performance. Upgrading to high-quality aftermarket lifters can often resolve this issue.

Milwaukee-Eight 114 Issues

While the Milwaukee-Eight 114 boasts improved performance over its smaller counterpart, it also presents a few challenges:

  • Wet Sumping: This occurs when excess oil accumulates in the crankcase or gear case instead of returning to the oil tank. Wet sumping can stress the engine’s components and reduce performance. Regular inspection and maintenance can help detect and address wet sumping early. In some cases, upgrading the oil pump can be beneficial.
  •  Oil Aeration: Oil aeration can lead to reduced lubrication and cooling efficiency. To combat this issue, owners should frequently check and replace their engine oil as recommended by Harley Davidson. Choosing high-quality oil and ensuring proper oil levels can make a significant difference in preventing aeration.
  •  Slow or Cold Starting: Some owners have reported difficulty starting the 114 engine in cold weather or during initial starts. Ensuring the battery is in good condition and using a battery tender during periods of non-use can help alleviate this issue.

Though both the Milwaukee-Eight Harley 107 vs 114 reliability have their respective challenges, proper maintenance and adherence to Harley Davidson’s guidelines can help owners address many of these issues and enjoy the best possible performance from their motorcycles.
