Kaya, who were runners-up in the United Football League last season, were surprisingly held to a 1-1 draw by Green Archers United in their opening group game on Tuesday.
However, Philippines international Burkey ensured there would be no repeat against Forza by opening the scoring after just six minutes, before adding a second in the 37th minute.
Reigning UFL champions Global failed to build on their 3-1 victory over Pasargad as they were held to a shock 0-0 draw by General Trias International.
Pachanga opened their Group C campaign by beating Mendiola FC 1991 3-0, thanks to a brace from Ariel Zerrudo and a 71st-minute penalty by Guam captain Jason Cunliffe.
The result was enough to see them claim an early lead in the group, ahead of Nomads on goal difference, after the Manila-based side beat Laos 1-0 courtesy of a 74th-minute winner from English striker Phil Connolly.
In Group D, Philippine Army saw off Stallions 2-0 thanks to first-half goals from Ricardo Becite and Luisito Brillantes, while Yanti Barsales and Randy Bela-Ong netted to give Philippine Air Force a 2-0 win over Agila.
