Question

13 multiple choice 1 point if you pull the enrichner on and the motorcycle runs better you know that you have a ____ condition.
○ high fuel level
○ lean
○ rich
○ low compression
14 true or false 1 point a motorcycle wheel bearing problem will always indicate a problem in the front end of the machine.
○ true
○ false

Explanation:

Question 13

The enrichner adds more fuel to the mixture. If the motorcycle runs better with the enrichner on, it means the original fuel - air mixture was too lean (not enough fuel). A high fuel level wouldn't be fixed by adding more fuel, a rich mixture would run worse with more fuel, and low compression is unrelated to the fuel - air mixture adjustment by the enrichner.

Motorcycles have wheel bearings in both the front and rear wheels. So a wheel bearing problem can occur in the rear end as well, not just the front end. Thus, the statement is false.

Answer:

B. lean
