be careful running anything with ester bean in it. A few years ago we kept getting extreme build up on our pistons and seizing rings in the piston. We were using klotz supertechniplate with 10% ester. We finally contacted klotz after exhausting every other possibility and they told us "If the rider isn't wide open all the time, the ester will not burn off clean" We were just learning at the time and racing Harescrambles, not mx. Just thought I would pass that along.

We run 42:1 castor927.
Something to remember is more oil in the mixture leaner the bike runs and vise versa. Alot of people think more oil better lube but you could be running lean and burn up a piston. Little FYI
