I have an 87 TRX 125 (wifes) that is tore down for a rebuild.(top end is trash) I am looking for info that someone has done an easy motor retrofit that has some more umppphhh! The 125 just doesn't get it. I am not looking to chop or modify the frame. Don't care about the reverse or electric start. I looked thru my piles of ATC 185/200 stuff and that will not interchange. I realize that one can only do so much with with a 4 stroke 125 so I hope to find someone that may have done an easy motor swap with a CL or SL or other motor.
