Desertpig,
Every time I look into the Saito 72 I think the 91 is the same weight, about the same price and is 45% more horsepower (per the specs). Why would I not want the 91 instead of the 72? .I am really close to ordering.

Then there is the YS63. I thought it was out of stock US wide. Now I learn Chief has them. It seems to need special fuel and I have seen comments about it being touchy to get running right. My favorite guru says YS is the way to go. The other expert says go Saito.

I am looking for easy operation with adequate power/wt and ok durability at this point. A Toyota instead of a Lambogini.
