    I have the original honda 125 modified to 167, had cylinder leakind problems because of bad welds in the power valve area. This is a big task with the honda, yamaha is much easier. The bike is a 1999, bored carb, stroked and uses a yamaha 250 pistin, the head seal is modified for o ring. Handles like a 125 with 250 power. Awsom. I have built 144 hondas and bore and stroke is changed with some metal removed from power valve.
