For any 4 stroke motor that is not running incredibly high compression you will actually not want to run anything over 100 octane. With fuel over 100 octane it will burn too slow and too cool, and you can actually start to lose power. The VP110 is a great option for fuel, but for your application i would mix it 50/50 with a premium pump fuel. The best option would be if you can utilize a non-ethanol pump fuel if available in your area. With mixing the 110 with a premium fuel, it will give the fuel some consistency that can be lacking in the fuel found at the pump. For all intents and purposes though, this kit would run fine on premium pump gas alone with the correct jetting.
