Re: lack of speed with Chicken Motor
The ratio of oil depends on the manufacturer. I would follow their recommendations. I used to run bikebug motors with Amsoil Sabre professional at around 75-1. I now use Opti- 2 at 100-1 on my HT motors. Some 2 cycle oils use a much richer mix, so it depends on the manufacturer. Not all oils are the same. I don't remember how many CCs the chicken power motor is. The bikebug was around 26 cc's if I remember right. It just depends on what you want the motor for. If you like to pedal, but just want some help on hills or want to cruise along on flats in the mid teens then it is great and I would think the Chicken power motor would be fine. If you're into some speed, greater weight of bicycle and rider or have a trailer, then it might not be adequate. But a running Chicken power motor on a period bike is very cool. I've posted a photo I lifted from the Moped Army website and now recall that the little gas tank was not a food can, but something like a contact cement can with a fitting soldered into the bottom. Very low tech, but the motor seemed well made to me...
Someday when I grow up I will probably lose interest in toys with wheels, but until then...
