From the photo that hole looks too big Tsimi. You're obviously gonna need to test it to see how she fits. If it fits, run it.

spaz12 The hole is OK the adapter has to go through the back plate so it is the right size. The adapter sits on the crank, most behind where the oil seal is and there the crank has a larger diameter, I think 15mm. Everything should fit, now that I know how to put all together I think it should work. I'll try it over the weekend and report back. I don't know if you can hold a back plate with the power of the front nut but that seems to be the only way to go with this Vario. I have another issue right now with the store that I bought this product from. 1.) The box was sealed with a Polini "High Quality" sticker but still the Vario drive face was full of finger prints and I mean really big, oily finger prints. 2.) The package should contain 6x3.8g and 6x3.2g rollers but I got 12x3.8g so 2 sets of 3.8 rollers. Again, box was sealed! Now feeling-wise I don't feel very pleased. It was on sale OK but this is not very professional. Either this product was on display in a store which would explain the prints and when they packed it they somehow put the wrong roller weights inside. This was done by the shop I bought it from or Polini. Either way they owe me "original Polini" 6x3.2g rollers now and shipping to Japan ain't cheap. I will write them later on and see.

I'd be irritated about the rollers, but wouldn't sweat the finger prints. The guy who boxed it up for you had probably just used the restroom and didn't wash his hand before boxing your fancy chrome backplate  |

Btw i just read this on a dutch webshop:
Bij montage van de Polini Hi Speed Evolution variateurs komt de electrische start te vervallen. Deze vario is alleen te monteren op Polini Evo krukassen met een 16mm krukastap of andere gladde krukassen met een 16mm tap.
It says that this variator can only be used with a Polini evo crank with 'blank' splines or something....aparently the Evo cranks are different from normal cranks.

spaz12  lucky that I used gloves and alcohol to clean them off.  The roller weight thing is sure not a big deal but I paid for something and I want to get what I paid for. I think the 3.2g rollers are anyway too light but you never know.... Lucass2T You are very welcome. If you need anything else measured or pictures just tell me anytime.

Lucass2T Yes that is what I read at first too that is why I got panic and wanted to cancel the order at first but looking around in other stores they all say that it works on a stock crank. The manual says it works. I will test it over the weekend and if it shouldn't work the shop will get another e-mail because they ensured me that it will work on a stock 13mm crank. In theory the installation should be the same on the evo crank. It has no splines so you will hold the back plate with the drive boss on the crank. The drive boss has 2 different inner diameters 13mm and 15mm so I guess that the larger diameter goes on the crank behind near the oil seal there where the starter clutch usually sits.

If it doesn't work then I sure hope they pay for the shipping.

Ok guys I couldn't keep stand and went out to install the Variator. Before I start, I didn't install the torque spring and anti-torsion thing that was included in the package, just the variator with 6x3.8g. I also have stiffer clutch springs in it. I used the long belt and the drive face of my other after market variator (diameter 100mm). Conclusion thus far; the Variator seems to somewhat work. And I know now why the back plate has no teeth. The back plate sits inside the case ring where the starter clutch usually sits on. I know it might not make sense what I say right now but if you once own one and install it you'll understand. 6x3.8g is too light for my Scooter and therefore it revs very high but it does somewhat accelerate. Maybe the high revs are needed for an Evo engine type of Scooter? Or the back plate is spinning through and therefore the rpms spike high?? It needs fine tuning and bit more test driving but I think that all is OK. After I tight down the nut on the front plate I tried to move the Variator by hand to see if the back plate only moves but it didn't so I think all is good there. I need to get one of those roller weight sets to have more rollers to test. So here some images again. Here usually sits a collar which needs to be removed.
Variator and drive boss installed.

I just wrote Scooter Attack an e-mail to see if they have more Info regarding this Variator and 13mm crank.
I was also thinking and looking at cranks and my question is, is there a 13mm splineless crank? As far I could see all are 16mm. There seems to be no 13mm splineless crank.

I get what you're saying. Never saw myself how it works when you install a variator fo which you have to remove the starter parts. Now it's clear. That collar does it....with this variator you hve much more travel right?

That collar does it....with this variator you hve much more travel right? Yes it suppose to have more travel. Thanks to 19x15.5 rollers and that deep/high back plate. I would like to give you more Info but I really just went one time around the block and that is not enough. Also I lack the roller weights, maybe a couple heavier ones will be better? I also might take a video over the weekend so that I can show you guys more details behind the back plate. I will remove the stiffer clutch springs, and install the Polini (8%) torque spring and go for another ride when I find time and report back. Roller weights gonna be an issue since I cannot get those very easy here.  The torque spring has the following written on it. L/38mm Kg.34 |

spaz12 Looks like you were right. The Polini factory really fucked up. The shop didn't open the product box so Polini not only put somebody's finger prints all over the drive face but also added 2x the same roller set.  I am glad that this kind of unprofessional behavior did not happen with my Polini Sport cylinder. It does leave some bitter taste though and I will think about it twice before ordering something from Polini again. Imagine, that Variator suppose to be their flag ship, top of the line. I cannot imagine to pay a large amount of money for an Evo crank or Evo cylinder only to find something missing, damaged or wrong with the product. If that is how Polini treats their products then....  Well I will get a partial refund for the rollers because, as I thought, shipping to Japan for a roller set is too expensive. Kinda feel sorry for the shop since it was not their fault but they have to deal with it now.
