I didn't even know it was happening, until Rock mentioned something about it in a thread I made about a variator failing. I went and looked at them a couple of days ago, and it is crazy how much those belts have grooved the variators. I will post pics this weekend, but the belts just wore grooves in them that I'm not sure pics will be able to show.
I had issues with the guide rails shearing on a couple of variators. Do ya'll think that was due to the kevlar belts?

Do ya'll think that was due to the kevlar belts? Do you mean the plastic v-slide guides broke and the guide rails on the. Variator were cut into ? What belts do u use ? I had a problem with v slides breaking , but it was due to bad tranny bearings causing too much tension on the variator . |

Check out the guid rail damage from the plastic v-slides breaking !  . Even with this much damage and tension causing the v slides to break , I had no grooving on the variator or drive face . If someone has groves wore into the variator or drive face , its either caused by very cheap belts" made with who knows what " and or very cheap variators and drive faces. |

I switched the variators I was using. I am using the DLH variator now, and I will update on how it is holding up. When I say the rails sheered off, they sheered off. I don't know if the guides broke first, or not. They sheered off right at the edge of the "wall" on the variator, so they were even with the "wall". I will post a link to the belts I have been getting lately. I cannot find a Gates "premium" belt in the 729 size, just the standard Gates. I have a 52mm BBK, and a regular belt will snap in there in a couple of days. I found these belts on ebay, and when you hold them, and compare them to regular belts, they just appear to be such a better quality. Performance, especially top speed, is increased greatly with these, also. RPM at top speed is 1500 RPM less with these than with a standard Gates belt. Anyways, here is the link to the belt. www.ebay.com/itm/KEVLAR-729-17-7-30-PREMIUM-CVT-DRIVE-BELT-GY6-49CC-50CC-139QMB-LONG-CASE-BELT-/271082023182?hash=item3f1dbf690e:g:n1UAAOSwo6lWMBu7 |

I would def pay attention t the new one. If it happened again I would possibly replace the tranny bearings ! That was the issue I had . |

When the variator starts going and the initial strumming of the belt begins so does the collateral damage to clutch shoes, the clutch shaft and the gear box bearings along with damage to the rear body and exhaust. I have seen a number of bikes going through this and most start patching mufflers, replacing snapped exhaust header bolts and replace the body parts that fracture or simply fall off instead of fixing the original problem caused by the poor quality or old failing belt.
