Yd's are for people that want a little more power, without any hassle. Not performance engine in the slightest sense. They last a long time though and give slightly more power than an out of the box 66. You want performance in a CG, get the 100cc steel sleeve. You want more than that, go hybrid. The YD's run a really rich fuel mix. I'm using 72-74 on them at 2200-2500 feet above sea level. It's the lower compression, needs more fuel. They also need a better balanced crank. lol.
