Pls correct your information
It had a rotary valve which is called suction plate in Pakistan just like yb100, a100x, kawi kh100/110/125 had
Yammy rx/dt etc, honda h100/mb had reed valves
Rotary valve gives better torque due to strong suction and precise timing, reeds are ok too but mechanics would mess them up and didnt lock their screws either eventually destroying the drivability of the engine and loose screws and reeds would get pulled into the engine and damage it badly
Which was then dubbed as âfail injannâ
Just because mechanics didnt know what the hell threadlocker was
