I just bought a Ranger Z20 w/ E-Tec 225 HO 25 hrs. on it manufactured in August, 2005. No updates have been done, sold by dealer with full warranty, picking up Friday. Are there any specific updates I need to request. I've already asked that the motor be set for XP100. Any mapping, lower unit or other concerns I should address prior to delivery? Thanks in advance for the input.
