Having run Saito's, YS's and OS four stroke, I'll add my thoughts. As I said, I have run different versions of all three makes of four stroke engines, and have had some very fine versions of all three. With that said, most of the folks that I have seen complaining about YS engines being "touchy" to set up, either "A" - Don't read/follow the directions, or "B" - learned on another make of four stroke engines and so assume any other engine that uses DIFFERENT (note I didn't say more difficult) set-ups and proceedures "must" be trickier to use. I will grant a person that YS engines ARE different to set up, tune, and run, BUT, if used the way they are designed, I have found mine to be every bit as simple to use as my other four strokes. And THEN there is the power and reliablity issue. My YS's have been tops in both areas for me. Do I have to use different fuel, plugs, and in some cases even props...yes, but then that is what the engines were designed to use!

I guess to me, if you have not already learned how to set up "other" brands of four strokes, and you start with a YS and learn it's correct set-up and handling, you might actually have an advantage over an "old timer", who has to re-learn certain aspects of engine set up when they get their first YS!

Just my two cents worth...
