I read some where you can use GY6 parts to make your own?

We've never came up with a homebrew solution here. I tired a GY6 50 rear pulley that is just barely larger in diameter. It didn't bolt up right though because of spacing on the primary drive shaft. 190mech has been messing with an Aprilia variator with some success, but it did require custom machine work. I tried to mod an aftermarket vari for more travel and it worked quite well... but not for long before it broke.

Tried some Dr. Pulley 7g sliders earlier today & I must admit, I HATED them!! They engaged the vari to the belt wayyy to early n didn't let the motor build rpm. I tried removing 1,2 & even 3 of them & testing and still the same issue. I'm wondering if the fact I have a polini vari had something to do w it?? Either way I'm now stuck w these sliders, Live n Learn.....

I'm thinking that maybe I should have gone w 5g's... yeah. i have found that 5.5g work best for me. Seems that 2t's like lighter rollers than 4t's. i think this is because 2t's operate at higher rpms. i wouldnt go any higher that 5g in a 2t. |

And...... of course it depends on the take-up pulley spring, the stronger spring you have installed (to combat belt slippage), the heavier the roller/slider you will have to install.

So u guys don't think the polini variator has anything to do w it?? I read that sliders don't work well w steeper ramps..?..

It could. I've always got the opposite effect with stock and Hoca variators and sliders. The sliders tend to increase RPM more initially than rollers. Have you tried rollers in the Polini vari?

Just sounds like the are 1. Like you said too heavy (im thinking this is it. FOR SURE if its a mina). Or 2. They are installed incorrectly? And i guess 3. You could be right about the vari as well. My overrange for instance. It dont like sliding weights! With my experiences Dr.P sliders work well with about all OEM style vari,s well. Very well for DD,s! But may not geometrically fit some aftermarket vari,s for best use?..When i tried em in my OR kit (19x15,s) it started acting more like a stock set-up with shift "humps" or drops in power and RPM,s in acceleration.
No matter the set-up, if you can get it (the engine) to stay at one (goal) RPM at about any given speed, you will get the most of your cvt

All I can say is that you can only run a variator with 3 or 6 rollers. Anything else will be out of balance.

Yesir, well aware of that. I was just trying different things out of frustration... Was really hoping the sliders would work out
