Time will tell. Thing is, in my experience, Yammi is hesitant to change things until several years into a model. For example, they knew they had premature starter failures in the VStar 1100s from 99-04, and it took them that long to correct it. On my four Yammi sleds, it was often three years before well-known issues were addressed.
Myself, I have not noticed quality control concerns in my two bikes, WaveRunners, sleds, generally speaking. They are all well-built, but, when problems do occur, they are slow to respond.
