I reached out to you via email multiple times. if you are ever online please let me know, I'm very interested in this bike.

Brammo Empulse / Re: Empulse Front Sprocket
« on: January 30, 2018, 04:12:10 PM »
Following up on that, an eBay search for the part number yields several 14T sprockets in stock from UK vendors:

If that is the correct part (I don't know if it is), then a quick Google search of the part number yields several results. Finding a 14T looks like it might be tough but if you don't mind adjusting your gear ratio (or compensating with the rear sprocket), the 13T looks readily available.

Brammo Enertia / Re: Brammo Enertia Basic 2012 showpiece - reduced range

The voltage of the least charged cell is <0.65V? If that's true then at least that cell is completely borked.
However, from your picture it appears the high cell is 3.706V and the low cell is 3.521V.

That's odd that leaving the charger connected would cause a problem, unless they weren't detecting 100% SOC in the software and turning off the charger.
What is true is that keeping cells at 100% SOC has a significant negative effect on their cycle life, although "100%" is a subjective SOC number created by Zero, you would have to compare the open circuit voltage of the cell to Farasis specs to see what it actually corresponds to.

Happy New Year! I am hoping to contribute a lot more this year as I am fairly new to this forum.
Interesting to hear the anecdote about the Farasis cells, I wonder if it is a cell issue or a software issue. Farasis makes pretty impressive claims about their cell capabilities.

Brammo Empulse / Re: Motor Sound/Vibration during Deceleration

What have you done to diagnose/how familiar are you with motorcycle maintenance? Have you checked chain tension? The chain can rub underneath the swingarm if it's loose.

I would be interested in the service laptop if you decide to separate it from the bike.

Brammo Empulse / Re: Charger shows 0 Amps
« on: August 29, 2017, 08:14:10 PM »
Two other possibilities, one is slim and the other may take more time to diagnose.
Have you verified the outlets you tested have power? An unpowered charge cable shouldn't cause the bike to power on like it does but maybe that is an oversight.
Secondly, have you read this thread? http://brammoforum.com/index.php?topic=3085.0
It seems there may a known issue of faulty connectors in the onboard charging system. To verify you would either need to go to a service center that can work on that component or disassemble and check it yourself.

I'm still learning about the specific hardware Brammo used, but it is a standard SAE J1772 connector, correct? It sounds to me like this could be an interlock issue. The two small pins on a J1772 connector are designed to disconnect before the high current lines disconnect, to prevent arcing across the high current connection. One of those pins is the interlock, or "proximity detector", which is used to detect when the charge cable is connected. That connection is also broken when you press the release button on the charge cable. IF that connection is not made, no current will flow.
Normally I would think this would throw a code in the Empulse's onboard diagnostics, but I'm not sure if it does, can anyone weigh in?
Since you used 2 different charge cables, it's likely the issue is not in the cable itself. You said you individually charged each module? How did you do this? Have you disassembled/disconnected anything on the bike?

Victory Empulse / Re: Mine is Dead now too

I'm glad Victory came through with a replacement bike! At least they followed through on supporting their customer in the end.
Clutchless shifting shouldn't cause any significant damage, provided you use the right technique. Most motorcycles (and I'm almost certain the IET transmission in the Empulse is one of them) use a constant mesh sequential transmission. That means all of the gears are meshed all of the time, but not connected to the output shaft until a "dog clutch" engages them. The dog clutch is what you direct with your foot, and locks the correct gear to the shaft. This video has a good visual explanation, it's difficult to conceptualize:
As a result, these transmissions don't "grind" in the same way a car's transmission does. The force of the shift is to the dog clutch, a robust part, and these types of transmissions are routinely shifted without a clutch in performance applications. The key technique is to engage the dog clutch when the transmission is unloaded, i.e. off throttle, and shift firmly and quickly. Quick shifters can do this by cutting spark for the miniscule amount of time it takes to slide into the next gear. Humans have to do it with a flick of the wrist
Here's more info on the Empulse transmission if anyone's interested: http://www.ietspa.com/portfolio-posts/iet/
TL;DR Clutchless shifting is fine if you shift when there is little load on the transmission and you shift firmly. Shifting with torque on the transmission could cause damage to the dog clutches eventually. The clutch only makes sure the transmission is unloaded during a shift.
