I bought my spare belt in April when AF1 had five in stock.  I just bought a spare to replace my 'spare' Lol.  Now they have one.  I wonder if COVID is affecting supply, in case anyone else wanted to hop on that last one.

I have ordered a few motorcycle parts and accessories recently from Amazon, Bike Bandit and Revzilla. About 50% of the items that I have ordered were said to be in stock on their computer systems and were later canceled because when they looked in the warehouse there were none to be found. In the case of Bike Bandit, I ordered two items and they never shipped. After waiting three weeks, I gave up and canceled my order. And so it goes during the Covid-19 situation. 

I have no idea what the situation is with AF1, but I bet they have a better idea of what they actually have in their warehouse than the big internet vendors.

I should also add that Revzilla's customer service staff was far and away the most apologetic of the bunch when they canceled my order. I received a personal message saying that the item that I ordered was not available in their warehouse and the vendor was not shipping any of more of their products at this time.

When AF1 found they didn't have the part I wanted, they reached out to me and Zero to get it.

So while they're a bit slower than modern online retailers, they're still pretty good.

My dealer was a little faster, but they don't keep stuff in stock and have to wait for Zero.  Which last fall was a little iffy.

A friend and I got the belt on last night.  It took over 3 hours.  Even with ratchet straps (per the video) it was impossible to compress the spring and lineup the swingarm to put those bolts back in.  We had to take off the monoshock bottom bolt to let it loose before we could put it back together.

Belt is on, but it's making a weird noise. Worse than when I first bought it. I'm not sure if the tension is correct because the Carbon Drive iPhone app and belt tension meter give wildly different results.  I'm also not sure it's perfectly straight as I spin the back wheel and I don't want to fuss with it anymore.  We were both exhausted after trying to muscle everything back together.

I'm going to take it to my dealer to get it all checked out.  This way if they make it perfect (hopefully!) I can take those measurements again and know what it's supposed to show.

The design of this bike to putting on a belt really sucks.  'Maybe it's easier with the S models.  For this reason alone, I'm seriously tempted to get the chain kit.

Maybe it's easier with the S models.

Only the SR/F and the SR/S have a new design that doesn't require to take the swing arm off in order to change the belt.

The belt have to be 1mm (a credid card thickness ) away from the lip of the wheel sprocket. The mechanical tool should give you the best reading.

And don't forget that new belts do tend to be noisy until they break in, which might take a few hundred miles. The belt on my 2018 S required almost 1000 miles before it finally became completely quiet and no longer made a "groaning" noise.

One other little factoid that I forgot about until now.  After I tested the new belt, my display is having a weird anomaly.

See the display LCD.  The top section of the time and bottom section of the battery percentage fades out when putting on the throttle.  At standstill, it comes back.  I'm fairly certain I put back any grounding wires attached to the back half of the bike, so this one is puzzling.

I suspect the belt of my 2020 FXS is way too tight, and reading through this thread has me worried. I bought a Krikit 91107 tension tester, and 9 times out of 10 the plastic piece doesn't deflect at all. Using the tester app I get consistent readings of about 46Hz, which is low, but in spec. I think the app is reading incorrectly because having watched a few youtube videos on tension testing, their belts seem to have tons of give compared to mine. Also, I don't know if it's related but my bike seems to groan a lot even at low speeds.

I'm fairly new at this, so pardon my ignorance. Do I need a jack or stand to change the tension? The manual doesn't say so, but it may be one of those assumed things. Thanks in advance.

Reading the comments im this post may help with the belt tension questions:

My 2020 DSR came with the tension a little low (38Hz on the app). I had some groaning and vibrations. I decided to adjust it by myself (very scary at the beginning). After a lot (20 or more times) of try and test, I found the correct tension and alignment (it was off also). Now the bike is very smooth with no vibrations and it accelerates faster.

I get consistent readings using the krikit and the app, but the measure changes depending on temperature and wheel position. Mine is now between 50hz - 65hz and 35-55kg.

I did ALL the changes without a stand, mostly because I was making some small changes, then trying, and repeat. I saw the dealer also doing it without a stand, but at least use a flat surface and don't forget to loose first and then tight everything before trying!

I am really scared about future belt snapping, because I had a very hard time adjusting mine and now it rides perfectly
I also want to upgrade tyres but I am scared as well of someone messing with my adjustments, so I will try to do both things at the same time when the belt gets old or the tyres too bad

I went back to the scene of the crime and found my belt on the side of the road.

[Crissa]

That picture makes it look like it broke across a tooth!  Definitely send that in to show them it was defective.  Someone else who had an early break said they asked for the belt.

By any chance was the belt lubricated?

The display problem is weird. I can't imagine it could be related. There is a ribbon cable somewhere in the dash not making good contact. People seem to be able to fix LCD problems like this by cleaning the connection with isopropyl alcohol and/or heat gun.

This is the one I use with my DS and SR to lift the bike off the ground to check and adjust the belt as well to do much other work on the Zeros.

For those how are in the same case, of a snapping belt on a FXS2020, you have since yesterday evening a new member of the club. Mine has also broken on a tooth, and I'm 100% sure tension wasn't the cause as a had verified it with a krikit last weekend.

If it could help others, I can make share some more pictures since I have the belt and except being snapped its looks as new, no degradation what's ever. Remark: the carbon fibers on the left part at the bottom have clearly broken internally in the belt.

I'm not a belt specialist but if this snapping would appear more spread, it do think it would help Zero if we try a centralise information on this forum.
