Keep an eye on it . when you get the new belts in , don't use the Kevlar belt until you found out what is going on. It would suck to mess it up. Also have you checked the plastic v-slide guides for any stress cracks ? That will also let you know if you def have a CVT issue.

Here are just a couple of my broken slides .  . The slides will show stress cracks on the right side " if looking at the variator as it sits in the CVT. |

i been having issues with my cvt also and just opened it up today. i thought my clutch was the problem. got it off but it didn't have any noticeable issue. i wasn't going to bother taking the clutch apart today, i had a new one to install. i did notice a huge worn spot on my belt. i guess since it was having problems disengaging on idle it was flapping around and hitting the bottom of the cover.
took my Koso variator off to install a used spare belt. as i was cleaning up my variator i noticed one of the plastic guides missing. OK, no big deal i have a few from my stock variator.... well, now i'm wondering why would one fall out. on closer inspection the thin piece of metal those guides slide on was seriously damaged. all 3 were worn down so bad my performance variator is now trash.
i'll post a pic tomorrow if i didn't explain that well enough. anyhow, as geh has said, it's likely something caused that belt to break so closely inspect everything before you put the cover back on.

I understand you perfectly. Those "v" guides suck. Some of those perf variators are expensive and because of those guides, I'll probably never order one of the more expensive ones unless I changed the guides out once every month or two regardless of wear. I will be changing mine out here early this week, once my belt, rollers, and guides come in the mail--- making a total of 5 guides I have. It's one of those things (the guides) to where there isn't much middle ground--- they're either broke or they aren't. There's been a few times I've checked them to where only half of a "v" guide was on the back plate. I've damaged at least 2 variators from metal to metal contact. |

I got over 4K km on my V-slides,,guess I better order some new ones soon huh?
Anybody know if the Dr.Pulley V-slides are any good,,they are only $1 more than the stock stuff at gy6store??

Tom I have quite a few miles on mine, also. I'm surprised yours aren't cracked yet on the sides, lol. Honestly though, I wish I had kept track of how many miles approximately I got on each set. I usually only change them twice a year, or once if I bought a new variator that came with them. I saw those Dr. Pulley ones when ordering the stock ones, but I have never tried them. Do they fit the stock variator back plate? On a side note, evidently my order came in on Saturday so I have it (rollers, belt, "v" guide/slides). I ordered the Dr. Pulley roller weights (not the slider weights) for the first time to try out. |

Have nothing to compare with, but have been using the Dr Pepper glides since the scoot had about 400 miles (now 2700). Because i was mucking around with variators I put a new set in that have been lying around forever - but the old Dr P ones didn't show any wear other than the normal blackened surface discoloration. Wish I had not tossed the old ones or I'd take a photo.

The only problem I've found with our Puerto Rico supplier is that for cheap items he does NOT ship Priority. So, for BBKs and the like you get used to really fast delivery (2 days to san diego, door to door) - but then he sends out a gasket set (or this time a pair of belts) and it seems to take forever.

I was pretty certain it was a clutch issue ,but because I also replaced all the tranny bearings the same time I replaced parts on the clutch , I'm not sure exactly what was causing the issue . after the v-slides break you have metal on metal contact, I'm surprised you had metal on metal damage even on the guides that did not have the broken v-slides. Actually I think it was 2 Koso's and three stock variators I destroyed. |

I lost many of them considering my CVT cover is opened up i n a couple places. |

There's been a few times I've checked them to where only half of a "v" guide was on the back plate. I've damaged at least 2 variators from metal to metal contact. I found that the red v-slides seem to be the strongest. Also if you are having issues with them breaking I would expect a problem with possibly the tranny bearings. The v-slides are pretty strong and will last a long time , even with a scoot that is modded to the max with a heavy rider. When it comes to our scoots and the mods we have the v-slides should never break within the life span of a good gates Kevlar belt . mine were breaking within 30-60 miles . the only thing wrong with my clutch was my pads were wore down to where it wasn't engaging until 4000 rpms. I bought new pads and new tranny bearings , replaced everything and the problem went away. Now the more I think about it the more I suspect the tranny bearings being the suspect. Even though the clutch wasn't engaging until 4000 rpms , it still slowly locked against the bell , it didn't all of a sudden grab the bell and lock up. Right now my clutch engages at nearly 3500 rpms with no issues what so ever with the v-slides. |

When I noticed mine "at the beginning of last summer" I bought a new koso. Not long after I noticed I messed up that koso , so I put in an old stock variator and took my clutch apart , cleaned it up and greased the bearings , however I ended up screwing up all but one of my stock variators until I changed the tranny bearings and clutch pads. I'm pretty sure you have an issue within either the clutch or tranny bearings . If you think about it , as long as the clutch isn't grabbing at takeoff I would think it the clutch would not be the issue. Once the clutch engages , all of the energy is transfered to the tranny and axle bearings. As the clutch is not engaged the energy is transfered back to the clutch pulley bearings as the pulley is spinning freely. Even if the clutch bearings were going bad I would not expect them to cause the broken v-slides, because the only time the clutch pulley is spinning freely is at lower rpms before the clutch engages on the bell. This is why I'm leaning towards the tranny bearings being bad. |
