Piranha 140cc Semi-Auto E-Start

YCF 125 upgrade

Bought the 140 to replace my 125cc in my YCF. Bolted right up. Some of the electronics didn’t fit exactly where the YCF electronics were located but was able to make it work with zip ties and some customized brackets. Engine runs strong, has more power then the 125 and have not had any problems in about 5 hours of riding time.

Not a good experience

Box was dropped at some point and the spark plug hit the carb and damaged it

Good engine

Great little engine for the money. Seems to run and shift great
