I'm not familiar with your trike but when you trike a 2 wheeler you add about 400+ lbs to it. Also if you were all ready close to the gross vehicle weight as a 2 wheeler that would over tax the drive train which effects the clutch first. Now with that being said sounds like you heated the clutch up and after it cooled off it was fine. You could just look and see what upgrading to a heavy duty clutch would cost VS replacing the trike unless you are leaning that way to start with. Good Luck
