So I'm sure I'm not the first to ask. But I've been looking around. And seeing talk about using a pocket bikes CVT transmission on the 4 stroke engines. Sounds like a pretty good idea from what I've read it helps give a good acceleration along with good top end. Anyone know more on this ? . . Anyway I'm sure the hoot gearbox I'm using probably isn't gona hold up too much longer. I've got about 150 miles on it. And it's starting to make a whining sound . . Plus I've read some pretty downsided opinions of them . .
