Inquiries to Rider
○Each rider reacts to problems in different ways, so it is important to confirm what kind of condition
 the rider is dissatisfied with.
○Try to find out exactly what problem occurs under exactly what conditions by asking the rider; know-
 ing this information may help you reproduce the problem in the shop.
○The diagnosis sheet will help prevent you from overlooking any keys, so always use it.
