® Quick Knowledge Test

Here's a quick, limited test of your general mechanical understanding of powersports vehicles, from the perspective of a career technician. This test was actually used to interview prospective hires among MMI students when I was a dealer service manager. Enjoy.

  1. What are carburetor bypass (or "transfer") ports? Where are they located, what do they do, and which carburetor circuit feeds them?
  2. When using a multimeter to measure electrical current, is the meter connected to the circuit in parallel or in series?
  3. Describe a voltage drop test on a charging system field coil.
  4. An engine won't start. The EGA reads higher than normal HC and zero CO. What is the problem?
  5. Raising a damper tube type fork's oil level will have what effect on the fork's action?
  6. Name the six parts of an AC-CDI system.
  7. Name the largest gear on a 5-speed, indirect-drive transmission's output or countershaft.
  8. When cutting a valve seat, which cutter is used to move the seat toward the combustion chamber?
