Good price for anyone looking for these. I use the 28g sliders (close to OEM) and am happy with them.

I have the sliding rolls + The sliding pieces, but still miss more oomph for my SW. I've tried to descripbe this for the maintenance guy, but perhaps I didn't manage to do it correctly. This is how it is decried by DrPulley "if you want to get more power at start, choose a stronger clutch spring to increase the starting rpm."
I tried to solve the issue by changing the variator adjuster spring to the white Malossi spring https://www.malossistore.eu/white-variator-adjuster-spring-ext-81x130mm-thread-7mm-15k-honda-silver-wing-600-4t-lc-2912478_W0-hosi600-M-P. Think it got a bit closer what I'm looking for.Sorry, I'm not very technical person, so I need a bit advice.
If you have been installed the hit performance clutch? Is it worth the money spent on it?

Leena, I’ve been using an HiT clutch for several years. At the prices offered it is well worth the money. I know that I paid a lot more when I got my HiT set.

An HiT clutch is not going to give you more oomph, but it will certainly allow the oomph that’s already there to transmit more efficiently to the rear wheel.

It does take a bit of fiddling to sort the clutch springs (for initial engagement) and the “pillow” springs, which “lock” the clutch shoes to the clutch bell at whatever rpm you choose. I finally settled on Black 10 kg springs for the clutch and Black 14.5 kg for the pillow springs.

IMHO The downside of any CVT transmission is the fact the it is very inefficient at delivering the engine horsepower to the rear wheel. Because an HiT clutch locks the clutch shoes to the clutch bell that goes a long way in reducing that inherent inefficiency.

But more initial oomph might just be a matter of switching to lighter variator weights too.

Tim, I use 24 g sliding rolls that seems to hit to the sweet spot on DrPulley table. The point where I need more oomph is when starting a bit uphill, I think SW isn't very hungry to start the ride then. That's more obvious if you stop on steeper hills and I've faced this specially on every trip in Norway.
But on a minor scale I find this every time, I leave home yard and have to twist the throttle more than I'd wish for. There is no technical issues on my SW, I think it's the feature of the bike. But according to the DRPulley site and your reply, the HIT clutch might be the answer.
Anyways, I think the discount is on some U.S. site, as I inquired about it on www.drpulley.shopnix.de site, they were not aware of any discounts.

Email Dr Pulley (Union Material) direct for the sale prices. They are aware that we have forum members in many other countries other than the USA so will be expecting non-US inquiries and orders.

Inquiries and orders: Service@UnionMaterial.com

Just checked the seller the price. It doesn't bother to order for me. The price plus PayPal´s commission plus the duty is almost the same as at the German DRPulley shop. There is also the risk not to get the product due to whatever reason, the post may lose the package (it has happened to me). Insured postage from Germany is 21€.
The matter may, of course, be completely different in USA.

Dear members,

Dr.Pulley had stopped the business with www.drpulley.shopnix.de since 2019 (announced on www.drpulley.co and many forums already).
In Germany you can get Dr.Pulley parts from https://www.sip-scootershop.com/en/search/Dr.Pulley?page=2.

Dr.Pulley RR, SR provided are all changed

RJ, I note that Dr Pulley's SR’s & RR’s are now made of “Black Pearl” material.  What is the difference between these and the original material composition?    ... or perhaps it is just a marketing exercise?

Hi,

1. First, the heat resistance of Black Pearl is higher than the previous ivory
roller and its dimensional stability are also improved.
2. Secondary, for marketing segmentation,

Thanks for your quick response.  Are there any data or test results comparing the ivory with the pearl units?

Will ivory or pearl SR and RR’s be shipped for your sale promotion items?
