I have Saito 1.00 and YS63-Z. Everything said above is true except Saito being better then YS.
Saito 82 will swing bigger prop then YS, but slower.
YS will swing smaller prop but a little faster with better throttle response.
There is nothing like throttle response from YS. It is better then electric
.
Once you try YS you will never look back.

Your post seems kind of contradictory and confusing. Quote "Saito is better then YS. Once you try YS you will never look back."
I have used both brands in larger displacements and both are good engines. IMO, Saitos are reliable and user friendly, but messier. YS engines are reliable, transition immediately, generally produce more power and have the advantage of using the pressurized fuel system. This is very important if you decide to move the fuel tank back closer to the CG. The Saito will require some type of pump or regulator at additional cost to be able to do this. It really boils down to whatever brand you prefer and can obtain the best support for.
