I am looking to purchase a new Honda ATV. I am looking at either the Rubicon or Forman 500 manual shift & steering . I want to keep it as simply as possible so I can repair it myself after the warrenty runs out. Which are more trouble free the air or liquid cooled ?Is there a major power difference between the two types of engines ? Is there any major problems with the power steering & electronic shift? Any input would be appreciated Thanks.
