I'm about to buy my first UCD and am trying to decide on the engine. Has anyone proven the YS-110 yet or is it still an unknown? The guys at my field are telling me the Saito's aren't known for their longevity when compared to OS. I like the thought of more power from the YS but don't want to weigh it down in favor of more power. I see that lots of you are using the Saito 100 and some are using pumps on them. Does this combo add up to the weight of the YS alone? Any thoughts? Thanks so much as I'm dying to make a decision.
