RE: Bigger engine for U-Can-Do .46?
I would try one but I have never seen anyone get a Y.S. to run where I am from, that is over many years as well, from 2 Stroke heli motors to the 4 bangers. Even the local guru with over 40+ yrs experience tried to get one to run correctly, he played with compression ratios, plugs, fuel and all sorts of ****y stuff and even he had trouble. They do not like the heat and humidity here I think, I bought a Y.S. 91 a few years back and was unimpressed with it, it did not have the power I have heard people rave about,they may be a dam fine motor in some parts of the world but not here.
