What in the world is a break in ???? I rode mine like i was going to ride it on the trails the first day i got it , i was told i while back from a friend that is a ranger dealer that all UTV and ATV's need to be done that way that the computer is setup to work with your driving style and the engine has a break in when it is built . I have no idea if this is true but anything i have had that was new i have done this way and have never had any problems.Question?? So once you get the new belt installed is there a break in period? Do you need to very your speed and run low and high for the belt to settle in? Just wondering if any one knew.
