I looked around and I can only find overrange variators for the small spline cranks. They are about $100 (some even including the fan), compared to $60 for the Hoca vari only. I think it would be worth the money if it would only fit. Every one of my scoots has the larger crank.
The sliders are fine. They are nicked up and such, but usable. That's another reason I've been happy switching to sliders. I've had a few CVT fails or issues of some sort and really haven't killed any sliders. I can't swear I woulda killed rollers in all cases either, but they definitely seemed more likely to get flat spotted, thrown out, or chewed up.

They lasted longer than I thought they would!There has to be a way to get the same result with out hanging on a sheet metal screw..We gotta think about that one...  How about making three pieces something like this so you can use 3 or 4 screws on there instead of just one? More surface area for the JBweld to stick to as well...  |

That might work. With more screws I could go a little smaller on the size too, so maybe it would leave the vari less prone to cracking. I gotta see what varis I have around before I see if I'm modding or buying or what. On closer inspection, that Doppler is just a larger face and bigger rollers. I'd need to go up on the belt size I'd think to do much with it. Then I wonder if it would be right in it's starting position. My main concern is clearing the belt at rest and still being able to get to the outside of something the size of a stock pulley. 60 would be plenty fast and I could do that with a stocker and a new belt I believe.

I'm thinking spring pins instead of screws would add more shear strength. Seems to me the G-forces alone would snap a small sheet metal screw even without the force of the back plate added to the mix. Maybe a combination of screw/spring pins to keep it all tight ? I'm not sure what kind of strength the JB weld brings to the table. It might cause an imbalance if it's not applied evenly.  |

had a couple of thoughts, maybe stupid ones  are the sliders or rollers large enough to close the Variator fully after you've modded it? or do you have to modify the roller guides? could you weld/ screw tabs onto the black metal part, instead of the variator? i mean the backing plate that the rollers push against  (see terrible diagram below) Attachments:

I think the guides would keep the ramp plate from sitting in the vari as it should.
You might be onto something about roller/slider size.
I dunno. I kinda gave up because I figured by the time I ever make 1 work I'll spend more than buying one or more.
