i ran benol and r50 in my zilla, never really had an issue but i also didn't mix it at 24:1, i mixed at 40:1
Bean oils are good but old school. They separate in the cold if that's a issue where you ride.
Synthetics are way better IMO. (with Torco GP-7 being the best)
Using a bean oil would be like running a bias ply tire on a new car..LOL
According to maxima which also makes a synthetic k2 two stroke oil.
"Just from a performance standpoint, if I were you I would most definitely use the Castor 927. Castor oil is the only lubricant that builds film strength under load as the oil molecule polymerizes and actually gets stronger creating more ring seal. I understand that there is another step involved when using 100% race fuel however, the performance and smell would be well worth it to me."
