Hey guys im new to this site, i just recently got a 1999 rm 125 for my lil bro and unfortunately the #$!^& who sold it to me neglected to mention that second gear was messed up, so now i need to invest in a 700 dollar gear set (installed with all parts). So as you can tell, im not happy, however i did find a 1998 motor, is there any chance at all that i can get that motor to fit in my bike using the ssame electronics, carb, exhaust etc?
