Hi. Like most of us i have this problem : https://zeromanual.com/wiki/Common_Problems#Groan_Sound
Can anybody give reference of acceptable lubricants (if possible available in Europe) ?
Are these fine : (Facom special plastics lubricant) :https://www.amazon.fr/gp/product/B00B7INIMQ/ref=ask_ql_qh_dp_hza
(WD 40 - plastics & caoutchouc polish) : https://www.amazon.fr/WD-40-33021-Sp%C3%A9cialiste-Lustreur-Silicone/dp/B00P0YLYCY/ref=sr_1_1?s=industrial&ie=UTF8&qid=1549265897&sr=1-1&keywords=wd-40+caoutchouc

I wouldn't use that product since it is designed as a silicone polish. I would use this stuff on your drive belt to help reduce the groan sound.

Not sold in Europe :-( Any other reference ?

I suppose you could go to an auto accessory store and look for rubber a "belt dressing" spray. ??? ICE cars seem to use lots of rubber belts to drive their engine accessories so there are bound to be products to keep their squeaking at bay. However, I have no idea if these products are a good idea to use on Zero's drive belt. They may have other silicone lubricants that might work too.

This one looks good "pure silicon oil, no solvent or grease" : https://www.esska.fr/esska_fr_s/Silicone-Spray-400ml-E-COLL-907284349390-16560.html,shoptype_set=b2c

Is candle wax harmful?

I think the "dry type" silicone spray is the best because it doesn't leave any residues that can attract dirt and gum up over time. If you can't find that, then the spray you provided in the link should be fine. I would not use a belt dressing as this stuff can be very sticky and will surely attract dirt in addition to making a mess.

I will make one comment about the groaning noise: My 2018 S groaned loudly when new. But after a while it quieted down and around 1000 miles the noise went completely away. Either that or I got used to it. ;)
-
That's my experience too. Time will make the groan much less noticeable, but I would still spray the belt with silicone every few weeks. It helps make the belt roll a lot easier too.
-
I only have this sound after the bike has been under the rain for dozens of minutes. it disappears after 1 hour or so.
I did not find the pure silicon spray. I find "belt sprays" (for marine applications), "pure silicon spray" (for home use like zippers fluidity).
Unfortunately this does not ship via air transportation. I'm still looking for a reference available in Europe (Uk/Germany/France...)

That is quite normal.
-
I know and except for the noise I did not experience anything bad, but the unofficial manuals tells that spraying pure silicone will avoid this for some time.
-
FWIW, this is the spray silicone I had on hand at home that I use on my belt.
-
Thanks ! I found this on ebay: klosterman belt spray https://www.ebay.fr/itm/282212092406
-
For what it's worth, the manual doesn't specify the silicone spray more precisely, partly because we're not certain what really works in the long-term yet, and partly to avoid endorsing a specific product or linking to a page on (say) Amazon or EBay or such that expires too readily.
-
Well klosterman is sold specificially for belts, so we can assume they would be dead by legal claims if it damaged the belt...

I have to think that it's the belt & not the bike.
Just this week I changed the belt on my 16DSR after shearing off many clogs.
My fault. About 19k miles on it & it happened.
Zero recommendations is to replace at 16k mikes.
Anyway, it's been quite wet here in SoCal & I had noticed that the old belt was making the notorious browning noise while wet from the rain yet silent when dry (I wear earplugs so silent is relitive).
The new belt is VERY noisy however and it hasn't even seen rain yet :P
I noticed that this new belt was vey glossy as compared to the previous belt when it was new so perhaps there was a change in the manufacturing process?

Are you sure you have the new belt aligned properly? About 1 MM (or at least a credit card space) on the very left side of the wheel sprocket. I know the belts can make noise if they are out of alignment.

The belt is not rubbing on the rear sheave/pulley edge.
There is adequate clearance.
It's the groan of the stretching of the belt.
The older one did it wet.
The new one does it dry.
It rained today & I was on the road soon after it stoped raining but the roads were still wet.
The belt actually seemed to quit groaning while wet.
Just the opposite of the previous belt :P
I check/adjust my belt around the first of each month.
Here is my notes on belt adjustment...
(This on a 16 DSR)
20-30kg tension via Gates krikit https://www.amazon.com/Gates-91107-Belt-Tension-Tester/dp/B000MUTAGS/ref=sr_1_1?ie=UTF8&qid=1549857086&sr=8-1&keywords=krikit+belt+tension+gauge (https://www.amazon.com/Gates-91107-Belt-Tension-Tester/dp/B000MUTAGS/ref=sr_1_1?ie=UTF8&qid=1549857086&sr=8-1&keywords=krikit+belt+tension+gauge)
Jacking left screw(bolt) out (adding tension) moves the belt to the right.
Best to get the belt in the correct position (left/right) then adjust tension.
NOTE: Position belt with a right side biases as it will shift to the left when the axle bolt is tightened.
Must use rolling head prybar to pry the right side towards its jack-screw (or just Smack the tire/rim in the desired direction)
Spin the wheel several times after an adjustment to allow the belt to settle down & find its new position.
NOTE: 1/6 turn of Left jack screw appears to cause a 10KG difference to tension.
Use 1-1/16" socket to tension axle nut to 102NM (75#/') when compleat (I don't have the correct Metric socket but found that 1-1/16" is close enough to work).
P.S. Recomend first removing each Jack bolt & grinding down the raised print on the heads to prevent digging into the soft aluminum of the swing arm.
Also apply some anti-seize to the threads before re-installing.
-
I think keeping the belt tension at the low end of the range also helps make the belt quieter. I keep mine a little below the low end range. I've never had a problem with keeping the belt on the looser side.
