Hi i have a 97 cr250 and i know its much better to run high octane gas. In the manual it says to run unleaded but around where i live its very hard to get unleaded high octane gas. Im curious what octane you guys are running and if its leaded or unleaded. I know in a car it will ruin the o2 sensors and cat, but this does not have either.
