Well, what year 125? If it's an 80-81 you are sort of out of luck. If it's 82 and later, just find a top end (cylinder-head-carb) from a yt175 and it bolts on. Buy you may want to find yourself the clutch basket assembly also as the 175 has a stouter clutch assembly for the added horsepower. Also the 175 has a diaphragm fuel pump to make sure you keep a good steady supply of fuel to that monster and also the 175 has a bigger fuel tank then the 125 and a slightly different airbox and the cover over the fuel tank is different as well because there is an intake on a yt175 fuel tank cover to channel more air into the airbox. Or there are other options if you really want to go crazy. LOL
