Hi guys as i mentioned previously i am new to 6x6 so anyways i purchased 2 max iv that where kept in a burn for over a year with out use and all the chains where rusted. Anyways i took it to a polaris repair shop and they greased them and flushed them with desil to get the rust out. Now here is my question since i am new to this and dont know how much power they should have i noticed that on concrete road or normal tarmac road when trying to turn fully from a stop to either left or right the max dose not turn a full 360 degree but rather a 60 degree and complete stops due to lack of power so i have to rev it up and then push on the left stick again and again keep repeating untill it turns a full 180 degree is that normal. Second one of them had the belt completly worn out that i know can cause lack of power but the one i tried to turn with the belt was new. The mechanic mentioned it could be the rust in chains and just needs a few drive hours to get them flexible again. Your help would be greatly appriciated
