2009 Yamaha ZUMA Service and Repair Manual
YW50YB is the factory code for the 2009 ZUMA. Look for Yamaha LIT-11616-ZU-50, which covers 2008 through 2011 in one binding.

One point about buying from a multi-year book. The procedures are shared, but a handful of specifications are not, and Yamaha marks those by year. Establish that your scooter is the YW50YB, then read the callouts as you work. The literature number LIT-11616-ZU-50 is the other half of the identification and appears on the manual itself, so a parts department can confirm coverage from their side without you describing the machine twice. Anything you measure against the book's wear limits will then be judged against the figures Yamaha intended for a 2009 ZUMA rather than a neighbouring year.
