For me I will say after seeing the YS180 run I am not keen on the fuel bill. An engine that can match the Saito 220 will be the YS160, however the YS needs a muffler system. The YS160 will throw a 20x8 for sure at about 9,000 RPM on 15% fuel, it will definately do it on 30% fuel and the consumption will be low. My YS110 is not a guzzler at all.
