There IS a BIG difference in biofuel engines. They are DIESEL engines with much higher compression then a china girl. Alcohol MADE from bio sources is what I assume you are talking about. Much different animal than a biofuel engine.
You can convert two strokes for alcohol use, but not biodiesel as far as I know.
Even if you could, why would you want to?
If more is better, then too much is just enough.
If you can't afford it, build it yourself.
