What are the reasons why a motorcycle cannot run fast?
1 Answers
There are mainly the following reasons why a motorcycle cannot run fast: Exhaust pipe blockage: The exhaust pipe is clogged with carbon deposits and soot, or the front curved section of the exhaust pipe is dented from impact. Such motorcycles have no issues at low speeds but cannot reach high speeds. Remove the exhaust pipe and use a drain cleaning spring or a hand drill with a steel wire rope to scrape off the internal carbon deposits, or burn off the carbon deposits with high-temperature fire. Air filter blockage: The rubber pipe is bent and obstructs airflow, or the foam plastic inside the air filter is clogged with dust, leading to severe fuel-rich conditions due to intake blockage. Straighten the intake pipe and clean the foam plastic in the air filter. If the air filter is normal, adjust the carburetor to prevent severe fuel-rich conditions.
