    I have the FH-5G-4Stroke:STD on my bicycle now, been running for over 2 years. Everything is fine.

    I just need a we bit more power. I would like to drop in a Predatory 79cc from Harbor freight.

    Can I just swap the motor out, or will I have to get a new Transmission? I seems like I can just get a new clutch flyweight, so that I can go from the tapered shaft to the straight shaft.

    Does anyone know?

    Thanks.

    I am working on a predator build now. The predator transmission is always listed alone. Do not think it will interchange.

    Did your predator engine come with dimensions for the screw hole mounts surrounding the output shaft?
    I can't seem to find any dimensions on the internet, all I can find is pictures and screw hole sizes.
