What really happened here?

Here is my interpretation of the entire situation, from CFMoto manufacturing, to the owner(s) "Voiding their warranties" by continuing to ride the bikes... according to QLink.

SPECIAL NOTE: LEFT = LEFT WHILE FACING THE VALVE COVER OF THE ENGINE. (Like sitting on the seat backwards.)

1. CFMoto was aware that there was a problem with the sealing of the head gasket in [certain] 2006, 150cc, water-cooled engines. These engines were destined for QLink, perhaps for the ECharm, but I have no evidence to support the latter.
2. CFMoto attempted to fix the problem by adding a small amount of RTV or sealant to the left side of the cylinder, and left side of the head.
   
3. CFMoto may have performed a QA (Quality Assurance) test on the engine prior to shipping, and it is feasible to assume that- if they did- the engine passed a seal test. I believe this could have happened simply because so many scooters were test ridden, and ridden following the sale, prior to mechanical failure and the coolant leak occurring.
4. CFMoto failed, for some time, to properly identify three key problems that were the root causes for the cylinder head gasket failure.
   
5. QLink may- or may not have- been aware of the conditions above.
6. The customer test drove the scooter, bought it, used it, and it eventually failed.
7. Some customers sought advice from their dealer.
   
8. Word has it that many dealers attempted some minor troubleshooting and repair. To my knowledge, not one single dealer fixed the issue after it occurred.
   
9. Some dealers advised their customer to keep riding the scooter, saying it would simply continue to run hot.
10. It is my impression that these dealers had no clue what they were doing, OR, that they wanted absolved of all responsibility in the matter. They probably assumed that the engine would eventually fail, and that QLink would either fix it, or their warranty would be voided. In either case, the dealer couldn't lose, unless the customer took them to small claims court and won. It may be that QLink was not aware that this was happening, and saw, only, a customer with hundreds of miles on their scooter following declaration of a problem.

Some of what is above is speculation on my part, but the following post shows facts.
