It might mean there's a glitch in the firmware, which could be resolved by an update.

The last time I took the bike to the dealer they updated the firmware. After a bit of research, I discovered that this was back in July 2015.  Unfortunately, getting the SR to the dealer is not exactly a simple task.  I have to borrow a trailer to tow it up there since the closest dealer is 150 miles away from me.  The only day that they are open which I also have the day off from work is Saturday.  I'm not sure how long a firmware update takes to complete but if it isn't something that I can wait for them to complete, I'd have to leave the bike there.  Each roundtrip takes approximately 6 hours.  I've had to do this once before when I was getting the cluster, tank bag, and charging cord replaced under warranty.  It's not impossible to accomplish but it is a giant pain.

Have you thought about getting snow tyres and an Aerostitch so you can ride all year round? I'd hate to not be able to ride for months each year
No thank you. The DOT excessively salts the roads around here during the winter.  I don't want that stuff anywhere near the electronics.  Besides that, riding in the winter is cold and miserable, not to mention the potential to crash is exponentially higher.  I have done it before when I was younger.  No desire to repeat the experience.

You can email logs to zero and then change the email address to yours (from the app).  You can then decode them using the online decoder here: http://home.hasslers.net/zerologparser (provided by cecil_t if you do a search on the forum).  Download both the BMS and Battery logs, the parser can handle both.  Kind of interesting to look at.

I finally managed to get both logs to download to my phone.  For whatever reason, the BMS file would not decode.  I was able to decode the MBB file and read through that.    I'm not even going to pretend like I know what the majority of the lines in the file stand for.   The first thing that jumped out at me was "CAN1 BIT0 error. count=1".  This line shows up a few times but only during the period where I had no response from the throttle.  I also spotted these:
"SEVCON CAN EMCY Frame      Error Code: 0x4000, Error Reg: 0x08, Sevcon Error Code: 0x4603, Data: 00 FF 00, Unknown" & "SEVCON CAN EMCY Frame      Error Code: 0x0000, Error Reg: 0x00, Sevcon Error Code: 0x4603, Data: 00 00 3E, Unknown" Each of these was followed by a few lines that were still in hexadecimal (except for the timestamp). These lines only appeared once each but they show up around the time where I was experiencing the jittery regen.

More than likely, it's a consequence of keeping your bike in storage. It could be as simple as some electrical contracts becoming tarnished or slightly corroded from lack of use. I'd try twisting the throttle with the power off lots of times to give it some use. Put the kickstand up and down, use the brakes. Anything with a switch or contact might just need easing up a bit to get it working properly.  Try spraying a bit of WD40 where it might help too.

I agree that being in storage is most likely the cause of my issue but I don't believe it was a hardware malfunction.  Best I could tell, everything was working like it was supposed to. For example, the "ready to go" light would turn on and off based on the position of the kickstand.  The throttle worked fine on the way there and, once I got the bike to respond to my commands, worked fine the whole way home.  I believe my issue was software related but I couldn't tell you exactly how.  The way I got it to move again was a mixture of plugging and unplugging the bike in combination with turning the bike on and off.  Essentially, I tricked the bike into working like it should.

I also never received any letter from Zero.

I tried to download the logs when I got home but the app seemed to freeze at 67%. I left it there for a few minutes but then i cancelled it when it didn't proceed any farther. Perhaps I'll go out and give it another shot later this evening.

I'm not thrilled about the lack of communication about the new instructions either. I can't fault the dealer I bought it from though because they went out of business shortly after I  purchased my SR. Would've been nice for Zero to contact owners instead of hiding the instructions on a back page of their website.

As far as looking through the log data, I don't have any way of doing that. All the information I have is based off the live data that was streamed to the app when I had it running earlier.

I know the bike will not prevent pulling away with the brake on. I know this because one time I held the front brake and gave it some throttle, mainly to see if I could do a burnout. Turns out the answer was yes and it's very easy to do so.

I saw the post about this here and on the Facebook owner's group page. As I understood it, the new recommendations are supposed to increase the longevity of the battery. However,  those recommendations didn't become public until after my bike was already placed into storage for the winter. This was the third winter of owning my zero, following the procedure as outlined in the owner's manual. I had no issues come springtime the other 2 years. Also, since riding it is the only way to discharge it to 60%, something I had no intentions of doing with snow on the roads, I chose to leave it on the charger until I needed it again.

I apologize in advance for the length but I feel that its better to be overly descriptive whenever an issue arises

Here's what happened:

A group of motorcycles from my area (all  ICE except for mine) decided to gather for a group ride. Since I hadn't ridden yet this year, I decided that I would join them for the first time. The meet up point was the local mall. Up to this point, my bike had been in the garage plugged in for the winter for probably about 5 months. I unplugged it, set the tire pressures, and set off. Made the 8 mile ride to the mall without issue.

After talking and waiting for others to arrive, we set off for our trip. Not even one mile in, I noticed that I wasn't getting any regen while braking (I primarily ride in custom mode 100% torque, 0% throttle regen, 100% brake regen, top speed 102).  This isn't the first time I've had this happen, a key cycle has always fixed this in the past. So I figured that I would cycle the key quickly while we were stopped at a red light to reset the system. This turned out to be a mistake, or a blessing, depending on how you look at it.

When the bike turned back on, I no longer had any response from the throttle.  The display was still showing 87% battery remaining but i couldn't get it to move. At this point, the warning lamp on the dash began flashing, one blink then a pause then three more flashes and then repeat.  I was now powerless at the red light and it of course turns green. So I coasted it onto the sidewalk and began troubleshooting, my fellow riders pulling off into the distance. (Not that it's pertinent to the story but they did notice my disappearance within a mile or so. I told them to go on without me)

I attempted a few more key cycles, I tried putting the kickstand up and down, even cycling the kill switch, all to no avail. When I switched the dash to display error codes, it read 0001 (which i was unable to locate what this meant).  As a last ditch effort, I removed the cover on the BMS and pressed the reset button. Still nothing.

I eventually decided to push the bike back into the mall and up to the building. (This is the possible blessing I mentioned earlier. I was still next to the mall instead of being stuck in the middle of nowhere on the side of the road)  At this point, I was hoping that a quick plug in to an outlet would bring the throttle back to life.  My newest issue was locating an outlet to use. After searching around and finding nothing, I went into the information/security office to request permission to bring it into the mall to an outlet right next to the door. They refused to allow it inside, but they did direct me to the ONE outlet they knew of outdoors. Of course it was at the other end of the mall from where my bike was because that's my luck. Nonetheless, I pushed it around to the outlet and plugged it in.

After just a few minutes of charging, I decided to try the throttle again. Still no response. So I left the bike turned on and plugged it back it. After a few different combinations of plugging in, unplugging,  and key cycles, success! I got the throttle to respond again. So I put the kickstand down to put the cord away and put my gear back on. When I put the kickstand up to leave, the green "ready to go" light came back on the dash but I had lost throttle and the warning light began flashing again, same pattern as before.

At this point I plugged it back in and began searching this forum to find if this had happened to anyone else. I found a couple other instances where other owners had the same problem. The fix seemed to be charge to 100% and magically it'll work again. Since I wasn't going anywhere anyways and I was already at 88%, I figured I'd give it a shot.

After about 40 minutes, the display read 98%. Now, a new interesting symptom emerged. The charger was now turning on and off, verified by both the dash and the app. The charger would activate for a few seconds, then off for a few seconds,  then back on. During this time, the charging indicator was remained blinking at its normal pace. However, the time to full display would cycle between 12 minutes and zero minutes in sync with when the app showed charge coming in.  I decided that this was close enough and decided to give the throttle another go. Still no response even with 100% battery.

I messed around with plug and key cycle combinations and managed to get the throttle to respond once more. This time I carefully held the bike up and got ready to ride again without using the kickstand. I got on the bike and everything seemed to be working. I immediately got on the highway and rode home as fast as traffic would allow.

The one malfunction I noticed during my ride back was once again the regen. For lack of a better term, it was "stuttering". Basically, it felt like it was activating ABS when regenerative braking. (When I say ABS, I'm equating it to the pulsation felt in the brake pedal when ABS activates in a car) I'm aware that my 2014 is not equipped with ABS, this just the best analogy I can think of to describe the feeling. The power/regen display on the dash confirmed that it was being caused by the regen. It would basically flicker whenever it went until regen. I decided to switch to sport mode since that employs the least amount of regen and managed to make it the rest of the way home.

The bike is now in the garage charging once more. I have no idea what the problem was/is. The only thing i can think of is that the pack is unbalanced. Before I unplugged it at the mall, the app showed a cell balance of around 50 mV even at 98% charge. I'm hoping that this was a one time fluke caused by being in storage for so long.

However, this incident has severely diminished my trust for my motorcycle. My bike only has a little over 3000 miles on it and only sees the outside on warm, dry, sunny days (a rare commodity here in upstate N.Y.). The length of my rides is already limited by the size of the battery since I don't have any form of quick charging, only the onboard charger. Admittedly, the SR has never failed me before today and I bought it brand new. But the 2 ICE motorcycles I owned before this (also purchased new) never left me stranded and I put many more miles on those, even through inclement weather.

In case anyone was curious, I dropped the bike off at the dealer on Saturday so that they could replace my tank bag & charging cord and update the software on the bike.  They got back to me on Monday saying that everything had been taken care of with the exception of the clock.  The dealer got in touch with Zero and said that the only way to fix the issue with the clock is to replace the entire cluster.  The cluster is on order and I am leaving the bike with them until it is fixed.  My bike is still under warranty so this will not cost me anything, just letting others know.

Mine also does the magical key cycle recharge. I think the largest jump I've seen it do was from 89% back up to 100%.

I've only ran my SR down to 00% one time and it was still moving under its own power. Power was severely limited but I wasn't pushing which was fine by me. My display never read 1%, instead it jumped from 2% to 0% and then back up to 2% when I gained some back going down a hill.  Also, according to the dash, I still had 2.4 miles of range, even after riding for a couple miles at 0%.

Zero Motorcycles Forum | 2013+ / 2014 SR Clock Malfunction
« on: June 26, 2015, 11:06:16 PM »
My 2014 SR has developed a non-serious and yet interesting issue.  I discovered it yesterday when I unplugged my bike and went to go for a ride.  The clock in the upper left corner of the dash will no longer display a time other than "00:00".  I tried to go in and reset the time but it will not respond to inputs. I can adjust anything else on the dash except the clock. It won't let me add hours or minutes or change between 12 hr & 24 hr modes. 

Also, when the dash runs its self-test at startup, at the very end the dash shows "EEE" where the speed is displayed but only for a second. Then the dash works as normal, with the exception of the clock. I'm assuming that "EEE" denotes an error of some sort and that the two are related. However, there are no error codes displayed on the dash.

I already have an appointment with the dealer to replace my tank bag (zipper broke off), my charging cord (3rd prong broke off but still works to charge the bike), and to perform a reflash on the computer on the 11th.  When I drop it off I'm going to mention the clock and have them fix it while its there.  Like I said at the beginning, its not a serious issue, everything else on the bike still works as it should.  Just putting my story out there in case anyone else has run into this.

Ooo good info ... Is that at all speeds? Like if you could check at 70,55,45,35,25,10 etc?

Rain finally held off long enough for me to get some riding time in. Due to traffic, I was only able to get up to 85 mph so I don't know if there is less regen at 90+ mph. I performed each test by pulling the front brake lever enough to activate the brake lights and regen but without involving the mechanical brakes. Here's what I found out:
~80-85 mph = -10 ft/lbs
~70 mph = -11 ft/lbs
~60 mph = -12 ft/lbs
~50 mph = -14 ft/lbs
~45-15 mph = -16 ft/lbs
15-10 mph = -10 ft/lbs
10-8 mph = -4 ft/lbs
<8 mph = 0 ft/lbs (no regen braking at these speeds)

Other interesting things I learned:
-The regen does not taper on but it does taper off at lower speeds. For example, I slowed from 81 mph to 50 mph (without releasing the brake lever) and the entire time the app showed -10 ft/lbs. My super accurate butt-accelerometer confirms that there was no increase in regen. It wasn't until I let off the brakes long enough to deactivate the regen and reapplied them that the regen would increase (also confirmed by app and butt-accelerometer).

-During a full battery, cold motor, full throttle pull from 0 mph, the app shows a peak torque of 144 ft/lbs at approx 35 mph. That's well north of 106 ft/lbs all the marketing materials claim.

-The speedometer on the app does not show the same speed as the dash. It consistently reads about 10% slow. For example, dash claimed 77 mph, app 70mph, dash 40 mph/app 36 mph, dash 30 mph/app 27 mph. This was the case at all speeds and was not due to lag or refresh rate of the app. Maintaining a constant speed confirmed this to be the case.

I didn't ride the bike to work today but if I remember I'll take notice of it next time I take it out.  Been raining a lot here these last few days.
