Yo man thanks for your reply,

i will give it a try .. i was running 8-667 witch was running great .. no problem just not sure if that caused my crankbearing to explode ..?
I doubt the fuel settings had anything to do with the crank bearing exploding. How often did you change the oil? I normally changed mine after every 1-2 tanks of fuel or quicker if I knocked on the rev limiter multiple times in a day.
