Re: what did you do to your motor bike today? I've ran as much as 8 ounces a gallon on REAL CHEAPO engines that I wasn't too sure of for break in. Some of these engines need all the help they can get. And like I said, I've NEVER blown an engine.(yet). Even after break in I'll still run a little heavy on the oil. Smokes a little but I'm sure it's getting enough. fatdaddy.
