What are the most common issues FZ V3 owners have after 3-4 years of ownership?

But as Yamaha FZ V3 ages, owners begin to face different problems that are not visible in newer bikes. In this topic we look at the common issues that pop up after a few years of use, and discuss the bike's long term reliability and maintenance requirements. Talk of wear and tear items such as chain and sprockets, electrical gremlins, and possible engine related problems is common. Some riders report excellent longevity with no recurring issues, while others tell tales of recurring issues. As often as not, the conversation revolves around how the bike's reliability can change over time based on riding habits, maintenance routines and factors of the environment. It's not clear how these typical problems compare to those of other bikes in the segment, or whether they are to be expected on a relatively affordable package that is supposedly aimed at imparting riding joy to absolute beginners.
