I hate to be the barer of bad news but you are beating a dead horse..I fought with Hisun and Massimo from the first day i owned it..They refused to honor warrenty , and laughed when i threatendd legal action..I tried bbb , consumer protection , attorney general..got no where..these people are untouchable..you will get nothing from them..find a local mechanic and pay cash..that was my solution..6 different breakdowns in first 6 months...I learned my lesson...only buy from a local actual orv dealer that you can sue if he screws you
