The cam chain tensioner failed while driving down the road, resulting in reduced power during a pass that almost resulted in an accident. There are no maintenance requirements for this component and there are numerous reports of this failing in motorcycles equipped with the Revolution Max engine. On this engine, the cam chain tensioner is held in place with a bolt that is apparently a torque to spec item with no locking mechanism. During the course of normal operation, the bolt backs out and can have varying degrees of damage. In this case, the forward cylinder cam chain became dislodged from the cams, resulting in a dead cylinder and eventually destroying the intake cam. A cursory check was done approximately 4 weeks prior to the incident, and no excess play was noted at that time. Note that there is no spec that I am aware of for excess play or interval to check it. This is a large enough issue that there are aftermarket companies that sell kits that contain Lock Tite on bolts to remedy this.

The charging system for the battery failed when I was on an out of state road trip. The voltage of the bike would drop between 11 and 12 volts when slowing down. I slowed down to make a tight turn on a canyon highway when the bike lost power and stalled. The motorcycle continued to stall several more times while in motion on the highway and I had a difficult time restarting the motorcycle on the side of the highway each time. I ended up purchasing a new battery thinking it would solve the problem. It worked for another few hundred miles until the new battery was also depleted and I had the same issue on the side of the highway outside Sedona. I had to rent a Uhaul for $551 to be able to return home safely. I took the motorcycle to the Harley Davidson dealership in Salt Lake City and paid approx. $1,248 to have the Stator and charging system replaced. Harley Davidson had released a service bulletin acknowledging charging system deficiencies on 2021-2023 Pan America models and subsequently redesigned the entire charging system for the 2024 model year. This is a documented pattern and not just an isolated failure. Regarding the repair in April 2024, the dealership replaced the failed stator with the same poorly designed part number instead of upgrading to the redesigned charging system.
