my 125 back end is so loose.

Should it be right loose or tight. because i can rock it so easy.

I bet the rear carier bearings are right wiped.....

I agree. The rear on mine is a bit loose and its the bearings/carrier. Also make sure you have your hubs on tight to the rim and the hubs are not sliding back and forth on the splines.
