yea i follow the 4x4 world josh and do you know who this is. i belong ot ranger forums as well under the name redranger_02 but anyways i know there are mods for this motor but it is just intersting to me that the razr is 330 pounds lighter and fuel injected. What is it going to take to get the teryx on par as speed is concerned with the razr? pipe intake cams possibly. That is another 1000 or more right there and considering you are spending almost 10 already on both machines depends on where you buy I dont see them being the best of the best yet. Allthough i am going to have to say i like the locking differential idea.
