Just had an email from Paul @ unionmaterial.com (the manufacturer of Dr Pulley Sliders) regarding lubrication of their sliders and rollers. here is his reply:
"Since the material used in our SR or RR is self-lubricated composite so in my opinion, there’s no need to put any lubricant ( solid or liquid type ) ."
But I have 6 sliders graphite covered waiting to be installed (hopefully tonight).

I tried dry graphite on my regular rollers before. I didn't like it, after a while it seemed like the graphite was actually making the roller hang up in the variator ramp. Haven't tried it with Sliders yet. Also apparently some vendors in the US are no longer including the Dr Pulley (brand) V-sliders with the set. If this happens to you, you DON"T want to use them with the regular stock V-sliders. I put a set in with the Dr Pulley V-sliders and they worked FANTASICALLY! They were without a doubt the single biggest performance gain of anything I had ever done to the Scooter. However my variator went out a week or so after I installed them and ruined the V-Sliders. So I replaced them with stock V-sliders and was VERY disappointed with the performance. So I couldn't find anybody with just the V-sliders by themselves so I order a whole new set. Now I have them and no Dr Pulley V-sliders came with them and nobody has them separate. So I'm stuck with brand new Sliders I can't use! I hope you got everything with your set!!

I tried dry graphite on my regular rollers before. I didn't like it, after a while it seemed like the graphite was actually making the roller hang up in the variator ramp. Did you use graphite grease? Dry graphite  (like using a HB pencil like this) can never cause the rollers to "hang up" as any "excess" graphite just blows away as dust.  After a while the graphite surface shines up like this. These rollers did 13000kms. Haven't tried it with Sliders yet. Also apparently some vendors in the US are no longer including the Dr Pulley (brand) V-sliders with the set. I'm confused about what "set" your talking about.  By a set I mean a set of Dr Pulley sliders like these If this happens to you, you DON"T want to use them with the regular stock V-sliders.

I guess you mean by Dr Pulley "V-sliders" actually sliders and by stock V-sliders you actually mean rollers. I did get 6 Dr Pulley sliders just as I ordered. Hope you get your problem sorted. Have a good one  |

Well took half an hour to get those slider in and an quick run just to make sure everything is OK before a test. The manufacturer said no lubrication was necessary, but after seeing how shiny the rollers was after about 7000kms of running with graphite, I gave the sliders the pencil graphite treatment.
Did a take off test with stock rollers and these sliders. Pick-up @ WOT is quicker and at the same distance from take-off the speed was about 10% higher.
I noticed something interesting during this test. The RPM just pegs at about 6000rpm with the rollers until 80kph and then rises linear with the speed. With the sliders the RPM seemed to peg at about 4800-5000rpm and then at a certain speed it felt like it changed a gear as the RPM shot to 6000rpm and then rose linear above 80kph.
Tonight we had our pesky gusty north-east wind off the sea - not ideal test conditions. On the motorway the RPM seems to be about 150 - 250rpm lower for the same speed, but I need to do some further testing. It did feel as if the pick-up from 110kph to 125kph was quicker even with a strong head-wind, but we'll have to see under better conditions as I was buffeted a lot.
Tried to do a top speed run, but only saw 140kph. I'll test it again.
I thought the Citycom's variator picked up was perfect in comparison with the Xingyue XY150's, but with these slider the pick-up is as smooth as silk and very linear. Just a steady pleasant rise in speed, that is taking it gently to get a feel for it. I guess their feel may change as they bed in.
So far so good ;D - me thinks it will be miles of smiles further ;D ;D

OK now I'm with you. No they did not include them, but then I did not expect them. I only expected slider weights. My stock v-sliders are still in good form. I treated them and the variator guides they run on with graphite about 7000kms too. |

Hey 666 most of the time one does get them with the V sliders and I have a set of 3 v sliders and on your website it is part# SP2012-E!
Now on the linhai which I have it takes 8 sliders and 4 of the v sliders but when I got my sliders they only sent me 3 of the v sliders like on the GY-6 variator! So take a look at that part number and if they'll work PM me and I'll give them to ya!! On my linhai the OEM v sliders worked fine with my 12 gram sliders that I installed! JRR

JRR, Thanks a lot! But unfortunately mine are the SP1613G. I really appreciate the offer though. Have you tried explaining your situation to the manufacturer? I know when I worked Tech support, my company would send out machines sometimes missing some add on parts to our dealers. When the dealer called to alert us of the mistake, I'd make sure to send double the amount they were asking for and for free. I know when I recently put in sliders, the "V's" came with them and my variator opens and closes much better with them. |

On their website they have them separate. So I guess that's how it should be, but I may be wrong.

I did a 180km trip this afternoon in very different scenarios. Motorway
and open country riding. In my mind the 19g Dr Pulley sliders do the trick. Revs
are down by about 250-500 RPM, a bit hard to judge exactly. I had strong wind
for a bit of the way and the scoot did 140kph top speed without me crouching
behind the screen. Overtaking now is quick as it runs at 7000 rpm at about 125
kph (all speeds are speedo indicated). Interesting take-off from stand-still is
about 10% faster. It will be interesting to see if my MPG change.
Happy scooting.

Well JR - I must go with your & manufacturer's advice - put sliders in with no lubrication.
After a few 1000kms I noticed my RPM creeping up again. Well I knew the belt needed changing @ over 16000kms, so when changing that I had a look in the variator too. I put graphite (HB pencil) on the rubbing surfaces of the sliders on installation and this got compacted at the outside of the variators sliding path. This caused the sliders not not go the full way and hence the higher RPM. Wiped all the graphite dust off everything, blew variator out with compressed air and now all is sweet again.
I also noticed from my previous markings on the variator that the belt runs about 1-2mm higher out on the variator. There is still about 2mm to the edge.
Now here is a question (& I patented this if it works ;D). With the way the sliders work, could one buy say in my case (19g now) use 21g sliders and take a bit off (say 1mm) the slider where it meets the outer of the variator which will allow it to slide a bit further and press the variator closed just that fraction?? This should take the weight back to 19g then too. What's your view on this??
Another 250RPM reduction will be good. ;D
Kiwiscoot
all runs good now on a new set of Michellin Grand Tourings, New Mitsiboshi belt & cleaned variator with Dr Pulley sliders.

Interesting thought Kiwi? Question what is the size belt you run? If you could get lucky and get a tad longer belt you would acheive the same thing. For instance my Bali will run nice with a 835 belt but even a touch better with a 842 and they do make a special order 846 which would be 11mm longer than the OEM 835 that came on it. I'm running the prodigy variator on this scooter and the 842 is almost to the very edge.
Another thing you can do is order you another center shaft or boss and machine off or shorten it by say by 1mm and it will push the variator plates closer together which will push the belt out to the outer edge more. Oh and BTW I hate to say I told you so on the lubrication but
I TOLD YOU SO!! LOL JRR

LOL -  I feel told off now.  Anyway I'll get over it. Learned my lesson, graphite works well for rollers, but not for sliders. From my measurements my belt is 1000mm long 24 mm outside width 19mm inside width. Now the belt could be 1005mm long too? measurement accuracy. I've tried to look, but don't seem to find anything close to that. Do one need to measure the thickness of the belt too?? |

Time perhaps for a long term review of the sliders.
From my records I put them in at about 13000-14000kms. The scoot has 29000kms on now.
It seems like they + the belt has worn and the scoot is pretty much back to the same rev's as it used to be with the factory setup. I have been very happy with the results sofar. @30000kms I will open the CVT and check the sliders and the belt, but I think they will be good for another 5000-10-000kms.
Happy riding and SYM - Smile Your Miles!
