So my bike is running like it is supposed to. lots of power no issues. however I switched to the "racing" 927 2 stroke oil at 32:1 ratio and the exhaust smells like a weird burning smell every once in a while. should I be concerned? or is that how this oil smells when it gets burned off or what? thanks folks.
