Don't know what we don't know? Carb pilot and main jet sizes? If NOT changed, lean air-fuel ratio high running temps could have cracked the piston?

Always perplexing WHY the BBK aggravation is acceptable . . as compared to selecting a 150cc scooter and leaving it stock? Unless this is "liquor cycle" situation, or lack of initiative to get a motorcycle license, very little scooter cost difference.

Example . . Icebear Vision 50cc $620 . . 150cc $640.
