125 sled

My cr125 doesn't seem to have the quickness off the line and low end speed that some posts I have read from other 2 strokes. What should I expect from the bike. I am 175 lbs. the power band is a different story. It will kick just fine but I don't know if something is wrong with the acceleration or if the bike is not suppose to jump off the line. What are some other experience. i see on here all the time that if you can push the kick starter down with your hand then time to rebuild. i was at the Honda dealer and tried it on some 125s and 250s, the 125 I could do with my hand, the 250s I could also but had to put more into it. It's not like I'm superman or anything but why the difference stories?
