Yamaha XT bike from mid 1980's

I'm sure it was an XT or XTZ but I must be wrong about the shaft drive. I can remember he was 2 up and every time he accelerated the back end would squat right down under the torque.  I must admit I can't remember it too well but was sure it was a Yam and not a Honda. I just seem to remember a bulky swinging arm on the near side. Damn my misspent youth.
