What are the symptoms of a clogged fuel filter in a motorcycle?

When a fuel filter is clogged, it restricts the flow of fuel to the engine. This reduced fuel supply can lead to hard starting because the engine may not receive the necessary fuel to initiate combustion effectively. Additionally, the diminished fuel flow results in reduced power during operation since the engine does not have enough fuel to perform optimally, impacting acceleration and overall performance. The symptoms arising from a clogged fuel filter are primarily related to fuel delivery issues, making the experience of starting and running the motorcycle more challenging.

The other options reflect outcomes that typically do not occur in the event of a clogged fuel filter, such as increased fuel efficiency or improved acceleration, which are contrary to the effects of limited fuel flow. Excessive oil consumption is also unrelated to fuel filter issues and is generally indicative of other engine problems. Hence, the recognition of hard starting and reduced power as symptoms of a clogged fuel filter is accurate and consistent with how fuel delivery systems operate in motorcycles.
