so for all around performance, hill climbing and speed, it sounds like you feel the gy6 150 can out perform the 250 especially in hill climbing. It is that top end variator that I think is the advantage of the 250.
However, I wonder if this is the best of all worlds, the 200cc gy6 B short case with built in transmission. As mentioned it can be bored and stroked to 232 and can use Taida parts. It has a built in oil cooler as well. If I remember right it has like a 123mm variator ramp.
