di kaya sira lang ang speedo?
hindi naman sir. talagang napabilis lang nung biglang baba nung slope.

nako! bakit sa jeepney driver ka kumuha ng teknik sa pagpreno
nagaya ko lang sir. nakasanayan ko kasi. puro sermon nga abot ko sa erpat ko pag kasama ko. ehehe

when you engine brake, just step of the gas and gradually step on the brake pedal. then downshift only as needed based on your RPM.
I've done it. Our ride doesn't have a tacho btw. I just base my step on the pedal purely on the sound and feel of the engine revs. thanks again. =)
