let me start out by saying hi. I am new here. I just recently traded my old beat up quad for a 87 dr125. it is the endure model. it has the headlight, taillight and the odometer. bike is in really really nice shape and starts on the first kick. was told the bike is all original with the exception of the handlebars. it looks it. when I ride it trough it seems kinda slow and sluggish. cant seem to stand it up either. it may be that I am used to riding 2-strokes but I thought it being a 125 it would have more power than what it does. any help would be appreciated. thank you in advance.
