Spot on information MaicoJames. After many years of 2T's I too found R30 or A747 does infact give an increase in power and throttle response. At last someone else has commented. Most I mention this too simply scoff at any such notion but eh, I can and have noticed this difference without a dyno! Hi octane pump fuel and A747 30:1 is my choice. This oil is no good for oil injected motors but for RM and the smaller bores where I mainly use it, it works like a beaudy. Oils ain't oils
