The 26-year-old - who reached the second round four years ago as a featherweight - lost to the Kazakh fighter on countback after the bout finished 12-12, a result that was neither appreciated by the crowd, himself, or team coach Oscar Fuentes.
While Fuentes stormed through refusing to talk -- Saylom expressed his frustration at losing out on what he thought was a merited victory over the fifth seed.
"I definitely had an extra point in the final round," said Saylom, a two-time winner of the King's Cup in Thailand.
"However, the judges didn't award it, maybe they only see one side of the ring," he added.
Saylom, who had been egged on by a vociferous group of supporters, said he was convinced he had done enough even after the final bell.
"Even after the third round I was certain I had won," he said.
"I believe I won but the judges decision says otherwise."
Saylom, who led 5-4 after the first round with the fight then being tied at 8-8 going into the final round, said he was not thinking of lodging an objection.
"However, my coach may feel otherwise."
