The list doesn't include sliders ideal for the Vespa GTS 300. Standard Dr.Pulley sliders are SR2117. There is no equivalent in the Black Pearl series to accommodate that size and weight.
Anybody found if that is correct.

If Dr. Pulley doesn't offer a particular size or weight in the black pearl yet, it's because they haven't sold through the old color yet.

I just got in a big order of Dr. Pulley sliders for one of my South American customers. She ordered sixteen of one size and weight, and two of the sets are black pearl sets, the others were the usual color.

I think the new Black Pearl sliders answers the age old question, "how do you get someone to buy your product again before they need to?" Add a bit of color to the mix and it's something new that you need to have. I suspect it's also cheaper to make them in a sort of black instead of a pure color like the one they use now.
One of the things I like about Piaggio and am surprised nobody else does, is the different weights in different colors. Dr. Pulley could do each weight in a size a different color, and that would make it easy to market and sell, sort of like the companies do now with clutch springs. They could paint all the springs the same color and just label them as to what they are, but it's more effective to use a color system. If you're tuning and you've got a big box of Malossi rollers with the print worn off, you need to weigh each one to make sure you have six of the same weight.
I can't wait to see the mindless reviews online about how much faster, more powerful, more even better and other nonsense, the new black pearl sliders are compared to the exact same thing in a different color they are replacing.

Let us know when they have a product for a BV350.

I received my set of black ones last week. I haven't got around to comparing then size by side yet and as I don't have a durometer here I won't be able to compare hardness between old and new.

At the same time I ordered a Dr. Pulley variator. I haven't got around to examining it carefully but I did note it came with weights that are 80% of original.

Not much experience with manufacturing, then?

They would have to do different runs in separate colours rather than just one run in the same colour.

All 19x17 use the same mould regardless of weight. They have enough different sizes already. Unlike Piaggio, say? Who only have a few.

You feel very strongly about this, don't you? It's good to see someone who is very passionate about the folly of making variator weights in different colors.
And thank you for explaining how the manufacturing process works. I think a lot of people have no idea how something can be made in different colors, and this explanation really clears it up. I can't emphasize enough how very helpful this information is and how much it contributes to my understanding of the manufacturing process of things in different colors. Until I read this, I thought crayons were all produced in the same color, but when they put the labels on them, that's when they changed.

I installed the Dr Pulley Variator and rollers a few years ago on my Scararbeo 250ie. It was awesome, made a big difference. Except I'm not sure that it was a good idea in the long term.

Recently my Beo died while I was riding on the freeway. Lost all power, when I had it towed to the mechanic he took it apart. Somehow the drive shaft's teeth had been stripped bare. They suspect it had something to do with the Dr Pulley variator. Anyway, the Beo is basically a write-off. I've got it back from them as I'm going to go to town on the engine and do all kinds of fun things at some point, but I just thought I'd warn you about the Dr Pulley variator.

They could always be painted on the end or have a dab of paint on during the inserting of the "weight" part. If one is going to automatically paint then mights as well simply paint the wight on them. Because yes once they are out of the packet, all bets are off. Same with J Costa. Size the same, weight different.

I bought a small digital scale.


(Also used for my previous hobby of slotcars)
Maybe we should add "scale" to "tachometer" as equipment necessary to play with variators.

Passionate? Not really I just like common sense which sadly with others is not that common anymore and I have a technical bent something which in others also seems in general decline.

So the ramp plate wore away the splines on the crankshaft?

Sounds as if the variator nut was not tight enough allowing the ramp plate to move. Maybe other ramp plates are softer material and they would wear not the shaft but I believe I have seen pictures of your suffering on MV somewhere else.

I found one. http://modernvespa.com/forum/topic164227?highlight=splines+worn

They would appear to be out there somewhere. But correct they are not on Unionmaterials website.

https://drpulley.shopnix.de/Dr-Pulley-SR-TechPulley-FR-sliding-rolls/Size-25x16mm-8x:::47_101.html

You could always but some 2517 and a piece of sandpaper? But I can't tell you how much weight you will lose. Maybe 0.5 gram?

If they are not on Dr Pulleys website, I bet those ones are counterfeits.

Hmmm. They are not on Unionmaterial's website and the German website does say "if available".

So I was thinking nothing more than BV350 has weird weights for which Dr. Pulley make not make that size,

Yes they are on their website in 3 weight options.

Confirmed by Dr. Pulley they are available. Here is a copy of 2019 catalogue.

The selection of weights is not mentioned so maybe we can revert to the German site information. They say 13,14,15,16, but you may be right with your 3. Stock is 16 so you'll need 14g which splits the 85% to 90% adage.
