84-86 TRX 200 fourtrax max towing

Hi, I'm not quite sure on the year but it's something around 84-86 and I have one.. and I was woundering what the max towing capacity it had.. in low range... Thanks! I want to use it for a drag. (Something for a dirt road) and my grandfather said I can use his tractor but I think it would be better to use my four wheeler.. if I can.. again thank you!
