Hello I just bought a new 2024 axis x550 I was impressed with the significant improvements they made from earlier models major improvements I realized it’s a bargain machine but for what I paid at lowes and the options it came with was surprising I was wondering if anyone knows how to purchase actual engine parts I do not have the ability to unlock rear differential the 750 version has a locker switch I can visibly see it’s a module I have a space for switch on dash would be nice to unlock rear differential seems like unnecessary stress on tires gears etc for no reason when driving on the road it is the same exact part that is on the 750 but I can’t seem to find a parts supplier that I can buy this mechanism from accessories are readily available but not engine parts any help would be much appreciated thank you in advance I just changed my break in oil after 10 hours of running was really thick compared to the 10/40 I replaced it with been riding and working on recreational vehicles for 30 years don’t know a lot about hisun engines but for what I paid and what I got and a 2 year warranty hard to beat just saying
