I've read about this.......I was looking into getting a yamaha before I bought the popo......
All my research pointed to that it is not actually boiling. It is in fact a venting issue and can be caused from overfilling the fuel tank and there was also a cause listed as a poorly designed vent system.....seems like you just had to replace to replace a small valve or something......not supposed to be a big deal...like $10 or something.
