Hey guys I posted this here because a lot of us run Dr Pulley sliders regardless of engine size. I read on the Burgman site that they occasionally flip over. I think this happened to mine as suddenly today I noticed it was a bit sluggish off idle and though it ran ok it didn't seem the same. It took too long to reach the proper rpm and was stuttering as it climbed to it. Anyone know about this have experience with it? Any way I am going to disassemble and inspect this weekend in the mean time I guess the Jonway will get some miles. Any way what do you think? This is on my 400 Burgman
Thanks for your thoughts in advance

How much wear in the ramps? Just could be a sign that the variator is now past it service life.
You might try and drop Dr. Pully a note and ask them at:
service@unionmaterial.com < service@unionmaterial.com>

The variator looked good and it has only 18k on it. The sliders have been in for less than 2k and it was a sudden change not gradual its fine at most rpms just not right on the bottom for a few seconds.

Anything is possible but I've never heard or seen that happen.

Glad you brought this up Rob. I switched to Dr. P sliders last summer. Installed all 6, 7G sliders and everything went well. The 7g sliders where a bit to heavy for my liking and ordered a set of 6g. Before i got the 6g sliders in the mail, something odd happened and had a change in RPM vrs SPEED.. just not right. Got the 6g sliders in and went to work putting in 3 of them as to have 3,7's and 3 6's= 6.5g. Anywho.. i noted that one of the 7's had been put in with the brass core the wrong direction and i think it might have been sticking a bit even thou everything was clean. It happens, even to the best of us now and then when we leave our glasses in the house and attempt a surgical procedure  So far i have 3,7's and 3 6's and all is good and it's been about 5-6 months now. Wish i could give ya a better insight but cant.. but wanted to give my input and NO im not saying you did it wrong, just what happened to me.  |

Then I would indeed send a note to Dr. Pulley and see what their take is on it. Wouldn't be a bad idea to put a set of calipers on them and the variator and see how far they have worn. |

since the clutch contra spring keeps the sliders in place i would guess there is a problem with the clutch or maybe the variator itself is somehow hanging on the crank journal.
i would try a good grease job on the variator first.
if that doesn't help then you might want to give the clutch a going over.
i've never heard of sliders flipping over.
keep us posted on what the problem is/ was.
the only other possibility is that the sliders are worn really bad.

I finally got the variator a part today and just as I thought it was a mess in there. I have thought a lot about this in the last week and I can't for the life of me figure out how it happened but, one apparently did flip and when I got it apart they were starting to shred. Cleaned it all out and reassembled with the original parts and its all back to normal. Normal was never bad... Maybe I'll try the Malossi weights next, I had the whole thing apart and back together including an oil change in less than an hour and a half so changing them is no big deal at all. I did borrow my neighbor's shop this time though man it made things easy.
BTW I did assemble everything correctly I took pictures because I had some idea that this was possible and I wanted to be sure I could show it was correct just in case. I looked at the pic before I disassembled too all was right. Anyway I did notice right before this whole problem started I had hit a rock about an inch in diameter with the rear tire so there was a sudden jolt. If any giant brained engineers (or anyone else who thinks they are blessed in the gray area) have any idea how this could happen when the whole thing is spinning at 5,500 rpm I would be glad to hear some theories cause I need to get my mind wrapped around it. It's really bugging me...

It was something about the tire slowing suddenly when you hit the rock making the belt loose for enough time for the variator to open more than normal and the roller/ slider to spin in place...... but it was worded soon damn confusing I even got confused even tho I'm the one who wrote it!

That is my current theory though it doesn't work in my head just yet. Thanks

I have also read on maxi scooters that sliders can fall out . At 13,500 mine have not ever done so . I did replace the glides at 12,000

Have you tried contacting Dr. Pulley about this yet? They may have more insight to share and might send you a better matched set of sliders or possibly a set of correctly sized rollers to replace what failed. Give them a chance to rememdy what may have been a defective or mislabled product.

Didn't do that the first time around. Sorry if i kinda hi-jacked a bit rob, but hey, i think i found the answer to my odd flippin deal.. lol It's about the only thing that makes sence, as i kinda was in a rush, had someone chattin away at me while im trying to operate and im not one to just up and ignore them-- you know.. being the nice guy |

This is on my 400 Burgman Thanks for your thoughts in advance Rob Saw that with a set of Ninja and KOSO sliders. One the belt was stretched beyond its service limit....the other... the guy put in a 738-16.5-28 belt vice 669-18-30 in his GY6 50. The stock variators must have opened too wide allowing their sliders to flip?...  |

I can see that too the belt was replaced at the same time though...
