How's it going? I was wondering if anyone else has belt wear issues like I do ? I always run a gates Kevlar 842 belt, and when it wears to a certain point my rpms begin to raise. I counter this by using heavier roller weights . Since I've been using the K&S variator I haven't noticed this issue , however the last couple times I tried a stronger main spring with heavier weights , then go back to the stock main spring with lighter weights , the belt seemed to wear considerably. I tried a 1000 main spring with 17 gram roller weights , and the rpms were just a tad too high, so I went back to 15.5 gram weights and the stock main spring , and the rpms were now also too high and I had to put the 17 gram weights in with the stock spring so the belt would climb fully on the variator. It seems as if the 1000 main and the 17gram weights wore the belt to a certain point. The problem isn't with the belt becoming thinner , it seems as if the sides of the belt are kind of glazed. Even with the koso I always had to fight this with upping the roller weight . would a belt dressing bring these belts back . its like the rubber has become hardened and the variators cannot grab them like they should. Any suggestions ? I have a ton of extra belts that I replace after about 2000 miles because of this . my recent belt has really close to 2k miles on it right now, but just like all of my other belts , its still over 18mm wide actually still pretty close to 19mm .

Just wipe the sides with a rag and a little warm water fast to wear the glaze off. Just did it today myself. The friction rubs the glaze off easy with some force. It's safe enough to not damage the threading or sides.

It's safe enough to not damage the threading or sides. I did wash it off with dish soap , but I really didn't scrub it. I wonder if I would lightly sand the sides with a medium grit sand paper , if that would help ? |

I took my belt off and scrubbed it with on of those cheap sponges with the green scrubbing side. I used the green side and I got the glaze off , so I imagine I should be able to go back to the lighter weights. Thanks lain !!
If this works , I'll have a bunch of good belts waiting to be reglazed !!

This is probably why the 1000 main would not work right with even 17 gram weights !

I avoid using anything but water. Don't need the belt absorbing soap. Scrubbing always seems to be good for any parts. Just scrub everything lol

How hot should the variator get ? I'm sure a hot CVT is normal , but what would be too hot ? I have problems with glazed belts. I have a fanless drive face , but my CVT cover is opened up in a few places to allow some of the heat to escape. If I go on a short trip , my variator is still so hot that I cannot touch it , at least not for more then a second or so. Even wearing glove I cannot hold it all that long. Is this normal ? Its been like this since I can remember.

A small electric fan on the CVT cover would be a good idea , however it would be wise to filter the air entering the CVT. We don't want and extra dirt in the CVT.

or water either. Mine has a washable foam element on it like a lawnmower would use.

I've been wanting to buy one like in the top pick. Those are pretty nice , but if I'm not mistaken they are a little pricey.
