I am too cheap to replace a good variator so they are ready to give up the ghost when I do so a new drive face is required. If they are already showing even the beginnings of grooving and the surfaces have already started to wear and arc why put a new flat true varitor face paired with an old drive face that's no longer perfectly flat.

I think the reason I've never had any grooves " or even any hint of grooves " after 20k + miles , is because the ncy finless drive face I used was made much better then the stock type drive faces. I did run my first koso variator for nearly 3 years with no grooves. Considering all the 125-150cc gy6 koso variators are all fake junk , I'm surprised it didn't show any type of hard wearing from the gates aramid belts. |

Some may think that if they eyeball things and do not use a steel rule to check the drive faces. What may look good the the eye can still be rippled, dished, arced, wavy and way out of spec when examined with a steel straight edge. Gates Aramid is good while Kevlar belts especially the cheap stiff ones with raw cord at the surface ready to grind drive faces away is very bad. Yes the softer bargain and fake drive faces will wear faster. |

Yes the softer bargain and fake drive faces will wear faster. I'm not sure if the cheap kevlars are real " Kevlar " or just aramid like all the name brands like , gates , Athena , mrp, and so on . I would not be surprised of the cheap knock offs are made of some kind of other material . I doubt its actually Kevlar. If so they could not sell then for $8 a belt . the Kevlar would be a little more expensive to actually make. They probably use some kind of hard a-s rubber that doesn't flex much . I have one of these belts in my arsenal " never used and never will be used, lol " it is so stiff and hard . I'd like to have someone take one and have it canalized to see what its made out of. They also usually snap really quick. I had 2 of them , tried one and it exploded into pieces in under 300 miles , actually it may have been 30 miles lol, I can't really remember. I made a post a few years back about it . but yeh , if they where Kevlar or aramid , they would not snap so easy . I'd bet money they are nothing but a very cheap hard rubber with cheap nylon cords. |

I actually still have everyone of my variators and drive faces I've ever ran , and no issues with grooves or waves, but I do agree that some may not catch it just by looking at them . wait I lied , I no longer have the k&s variator .

The Bando Branded one I dealt with was hands down the worst and most abrasive however it could have been a fake or even made with some old steel tire belting. The sides snagged at you and felt like small needles,

The sides snagged at you and felt like small needles, Wow , really ? These belts , even the aramid belts should have no material that would poke you like needles! Just like the metal threads showing on a wore out tire ? If this is the case , then this solves everything. A belt made of that type of material would def cause some big issues and def put grooves in the variator ! |

I know we all look at Kevlar as being stronger than steel , but first off , these belts are not made of Kevlar . they are aramid . if some of these belts are running metal in the belt , this is the reason for the grooves. Even if there were a true Kevlar belt , I'd expect a belt with metal threads will cause grooves before a true Kevlar belt would . Kevlar may be stronger then steel , but the steel is much more abrasive then the smooth Kevlar fibers.
If someone is running a true gates aramid belt , and it causes grooves , I'd look at a CVT issue or a very cheap variator or drive face.
