Title: Dr Pulley sliders NO GOOD!
Post by: zevsdad on September 13, 2016, 08:22:17 PM
Well I wanted to like them what with all the loose talk around these parts ---but.... here's the problem: THEY DON'T LAST!!!!! I changed out the factory rollers after around 2 years of happy, paper crunching noise -free riding. Well I can report that after a mere 7 months of riding the sliders that the paper crunching noise is back - and its WORSE THAN EVER. sorry about the caps shouting but I'm a little frustrated that after all that work the sliders only lasted 1/2 a year.

I ordered OEM rollers, brake pads, and a key spare from this place, with FREE shipping:

Chaparral Motorsports



I highly recommend it over kymco rip-off monster--where they actually have the balls to charge 20 bucks for shipping

Why some people have good luck with sliders and others do not. Most say the washers have to be installed in a certain way to prevent problems.
I installed Dr Pulley sliders about 3000 miles ago. So far, no problems.
Knock on wood.

2011 downtown 300i       30,000 miles on one set of sliders and good for lots more 20/12   15 grams    if I can get my scale back from the pot smokers, I will weigh them next oil change,.  KILL THE KIDS!!THEY ARE IN THERE 30,S   I TELL THEM ITS MAKING THEM DUMB,.

    I installed stock weight Dr sliders and couldn't be happier. Can't say how many miles ago that was, but 2-3 thousand anyway. Yes I know, not a lot of miles but when you have 5 bikes licensed the Kymco has to wait it's turn to run up miles. I have hard numbers to show a marked improvement in acceleration, not just seat of the pants. Did the same with my  SYM HD200 but had no change in performance.

I've had mine in for about 3500 miles with no problems. The increased performance made it a no-brainer for me.

I have tried sliders and rollers. I went back to rollers. Sliders felt better but in real world tests did not perform better. The ramps are designed for round things. The scooters were engineered for round things. If you disagree with me that's fine, just don't be dissing my motor oil!  ;)

Strongly agree. The Dr Pulley sliders work better with the Dr Pulley variation.  Matching shapes!
I ordered the 14 gram 20×12 round rollers. Can't wait to see how they perform with a Zard exhaust.

Yep. If you look at the Dr. Pulley video, the variator is not a stock one. It is a Dr. Pulley that is designed for the sliders. Kind of misleading.

I guess...but have Dr Pulley sliders in my Kymco and new Burgman 400...with stock cvt parts....work just fine.
Have not seen a dealer selling these sliders that mentions a problem using stock cvt parts.  Nor recall any forum mentions in Honda...Burgman sites stating the need for buying Dr Pulley variator in order to make the slide weights work without problems in a stock cvt.
Most just add these weights and button it up with good results.
I have.

They worked fine for me too Stig. Just not overall as well as the Dr. Pulley round weights I put in. The sliders "felt" better but in objective testing did not perform better, for me anyway.

Heck, I put some stock weight ones in my S200 and the difference was notable.
Just going to get around to pulling them for a peek and a housing cleaning in the next week or so, but they went a long way towards killing the dead spot in acceleration along with fatter jetting.
Overall I'm a fan, at least on the S200, the other similar scoot I've worked on was the HD200 which was fine with the stock rollers, so can't say there.

I reported elsewhere on this forum that my sliders melted, and the outer variator face on my 500 stripped it's spline, so I will be staying away from them from now on.
I have ordered a malossi sports variator instead, and I will report my findings after a bit of a test.

Let's us know how you find that Multivar 2000. I would be interested to see the performance difference.

I cant seem to find the thread anywhere. How did the Multivar work compared to the OEM?

I've been using this particular set for the last week. I have been pretty impressed with them. Faster acceleration, higher RPMs, midrange power and is the same, and top end is about the same.
Pretty much same effect as the Dr Pulleys. I got them just to try and I can report that I'm quite happy with them. I am going to install a Mivv exhaust soon and hopefully this will be the perfect combination.

I have put the DP Sliders in my 2011 downtown 14gr and they are fantastic. From the line and mid range much improved. Top end about the same. 15 would drop the rpms some on top end and probably give a little more speed at the detriment of low end performance.

Having said all of that I want to speak up on the topic of Sliders versus rollers and the comment about ramp geometry not being congruent. THAT is not true 95% of the time on all scooters. Sliders are an awesome and a no brainer improvement that almost without exception provide improvements in a couple of ways. I don't mean to take away from anyone's opinion or preference but this has been the real world experience I have had.

I have had sliders in my Downtown 300, Burgman 400 (30k miles), HD 200 , majesty 400, BV 500, people 250, Honda Helix, MP3 250, MP3 400, MP3 500,  ridicuous amounts of Chinese bikes and had excellent results without exception. Some of these bikes for 10-30 K miles. Some of these were group members bikes. More info avail upon request.

I now own a People 300 and am about to put sliders in it. Don't fear the sliders they are ROCK solid...in the one catastrophic failure mentioned on this board there could have been extenuating circumstances that could have caused it. Again not trying to tear down anyone's experiences or comments but rather calm any fears and set the record straight on Dr pulley sliders ...don't by clone slider IMHO.

Hello guys.

So....I decided to do a belt change, variator, and torque driver inspection. Removed the entire drive system with belt. To my surprise I found that 2 of my Dr Pulley sliders had shifted it's position in the variator housing.

I decided to go back to the OEM rollers as I feel that it's a better fit and runs better.

Please guys, when inspecting your sliders make sure that they have not shifted in any way.

So I would like to give an update on a couple of things. Sliders have been known to "Flip" as mentioned earlier. When installed some dry lube can help and insuring you have a properly lubed drive boss is important. It is also common for people to allow the sliders to flip during installation. I did this more than once the first time I installed them on my Burgman. After one flips it is more likely an additional slider can flip. You can usually tell it happens by a change in rpms and reduction in performance. Don't worry just take CVT apart and clean everything and put back together being careful.


Since my last post I have installed the 14 gram sliders in my People 300. (Yes I have a DT 300 as well, )
I have only put about 100 miles on this bike since installation  but the performance increase is terrific. From a dead stop it gained, from the middle it is a beast now and on the top ending is more responsive. It gained about 5-6 mph on top end.

Thanks guys, my opinion is that the OEM rollers deliver more torque on the low end and just as much torque and speed on the top. Better for pulling hills. Just my opinion.

I have a set of 14 gr rollers which I will try as well. Should get some good results.
I will post my experience.
