The variators are built to not allow the belt to get to the edge for safety so that the belt does not have a chance to pop off.
The belts you will find will travel no higher than approx 1/8 from the edge on any given variator. So if you can get your belt to climb within 1/8 of the variator edge you cannot get any better than that.

It seems obvious that if the belt is 20mm wide then the smallest width the variator should have when the pulleys are together is 20mm at the top. I saw a video the other day where a guy's belt was riding halfway out of the variator but I think he had modified his pulley with a file if I'm not mistaken about which video it was. |

Exactly why in your variator mod thread, why I said how dangerous it could be to go messing with these things. My current setup goes all the way to the top with rollers. I want to try sliders just for giggles. However, now I've decided to hold off as I'm about to upgrade my entire CVT. With the issues I'm having with my clutch slipping I've decided to upgrade my clutch. I'm looking at the NCY Trans Set. Their clutch looks like it will perform better and is over 2 pounds lighter than stock. 2 pounds less of rotational mass on these little engines will make a big difference. The variator that comes with the kit is also lighter than even the Dr Pully variator. It's drive face is slot cut for cooling and even though it's 115mm it has about 1/4 of an inch of material removed from the edge but the fins (that are also much shorter than stock) still extend the full 115mm. The idea behind this is to to provide better cooling to the belt at high RPMs. It also has a few other major improvement that I'm not going to get into..it's late!  |

I would not run mine like that. Every time I put my cvt together I rev it up and see how high the belt goes. Sounds like the people making the variator you want are making a lot of cuts and chops on theirs. I suppose they have done their homework and testing. I know I would before selling something like that. Sounds nice, especially the three pound drop in clutch weight. |

Oh. It looks like a few ounces of weight loss, not pounds.
