So a few people talking about the 600 mile (and subsequent) recommissioning supposedly required for our motors. I never did mine, but will probably try it myself when my ixxat comes in. Going to the dealer is a major hassle, and they are kind of incompetent, so I don't trust them with the bike.

The rest of you?

Around 7,500 miles on each of my Zeros. And both of them have had zero service anywhere other than minor stuff done by me. They both run as well as ever.  Both are many versions of FW behind.

I don't think recommissioning is something that you can do yourself. I think you need to be on-line with Zero on the Zero website to use their program that only dealers have access to. And the Zero dealer here in Reno doesn't even know that much. They know zero about Zeros, but still sell them.

I had my motor recommissioned  when the 600-mile service was performed last year on my 2018 S.  I was charged for 1.75 hours of labor, which included a lot of checking and inspection of the chassis and other random parts on the bike. No parts were needed.

I had my 600 mile service done shortly after buying. They did it while I waited, about 90 minutes. The manual section 6.2 says "the initial maintenance is vitally important and must not be neglected." It's reasonable to assume commissioning is needed and the warranty could be impacted. My dealer is top notch.

Now I'm going on 3 years and 8000 miles, having maintained nothing but the belt tension, tire pressure and brake fluid. While 4K service does not call for commissioning, 8K does. I'll take it in soon for 8K, and will also get new tires (same ones) and fork oil. The tires are great and have lasted unbelievably long.

I insist on no firmware upgrade. Everything is perfect. From my perspective, flashing it can only make things worse. How can I prevent accidental flashing? Can I make the EPROM read-only? Can I tape off the connector, or is the same connector needed for commissioning?

That doesn't make any sense. Commissioning is only between the motor and controller so you'd think sevcon's software can do it. I'll find out in a couple days.

[MVetter]

Sevcon's software suuuuuuuuuuuuuuuuuuuuuuuuuuucks

Did you want to explain why?

[bergercurtis]

Give us your take in a couple of days. Our demo SR/F is coming up on 600 miles, so I can see what I can find out on it too.

[alko]

Bought my 2017 dsr with 1200 miles on it. 8000 on it now. How can I tell if the 600 mile service was ever done? Call Zero? They never mentioned it when i transfered ownership.

The part you're missing is the wheel has to be spinning off the ground as the bike is logged in to a website that somehow shows the controller  pulses in relation to the motor rotor position. I hear it is done on a monitor, kinda like a video game. The good news is that it is hard to screw up when once set up.  Something like match up a bunch of dots, save it to the bike and it's done. Simple, be we cannot do it ourselves. I would love to be wrong on this!

I have never seen it done myself. But some others here have who can probably tell you more.

Getting the wheel off the ground is trivial and according to the Gen4 manual commissioning is part of the Sevcon software. This isn't a special zero thing as far as I can tell.

If you discover there is a way for the owners to do it, please post the info. here.

I had mine done at 600 miles, it was a small bit off at that point. Dealer charged me an hour of work.

From what I understand its the sevcon statically understanding where exactly the magnets are in the rotor in correlation with the angle of rotor rotation. I guess a fraction of a degree can make a big deal. But.. I dont understand why it cant figure this out dynamically and periodically update itself.

That and why does it drift?
I can understand the precision to which the calibration must be made but being this is electronics, why does it change overtime? What wears out or moves to cause the need to re calibrate?
This sounds a lot like the old ignition systems on ICE vehicles in days of yore, where you had to use a timing light to adjust the spark to near top dead center as the ignition points wore out.

Just bizarre

I've got 600 mile service scheduled for 8/12 for my SR/F.  I'll see if I can watch (planning on waiting for it anyway).  I'm at 1300 miles (oops).
