Re: Hi Folks, Joaquin Suave checking in.
Welcome to the forum.
I personally haven't found any small suitable (and/or affordable) diesel motors, but it never hurts to keep looking. I would love to have a biodiesel bike.
I know a couple people have tried already, but it would also be nice to have an E-85 powered 2 stroke motor. E-85 plus that 2-stroke oil that's made from animal fat...I'd call that a little green.
