Hi I noticed your post after I wrote my question regarding a purchase of a outlander 400 max HO xt. One question I have is about the carbureted engine vs. the EFI. What is the difference? Do you notice it? What is your top speed? I wanted a 2 person and will use it mostly for ice fishing but may go off roading with friends a few times. Any other information is greatly appreciated because this is my 1st time atv purchase and I am trying to get up to speed before I buy one.
