Do not let that laptop out of your sight! I'm sure there's many of us here on the forum that would love to make a copy of your hard drive. I can make a run up anytime you're available!

I'm pretty sure Alta incorporated safeguards to prevent damage from anyone running the pack totally empty. The BMS will shut off the pack at a voltage specified by Alta to prevent damage to the cells. The only "extra" battery in the bike is the little 9v battery housed inside the main ECU...

There are plenty of open source EV displays available from a simple pack SOC indicator to full on computers. The problem is that all the sensor data is encoded via CAN. And although the displays mentioned have CAN capability it's worthless without Alta's CAN database. I suspect if someone...

I'd suspect a combination tight chain and mud pack between the chain and sprocket. A tight chain can mimic those symptoms.

I haven't looked and as far as I know nobody's has figured out that plug yet. Look closely for a manufacture code or part number and google it. Might be pretty easy. If you find one (and it's mating part) you can build a "break out" box and have very easy access to all those circuits for...

I'm not totally familiar with euro standard wiring, but in the US you should have approx. 230v between the (white wire) and output side of fuse (black wire). Should have approx. 115v between white wire and yellow/green wire (or case) AND 115v between black wire and yellow/green (or case)...

Brian, Sorry I didn't make it yesterday, I noticed my fork seals were leaking pretty bad. I had done some "anti-stiction" mods and while they certainly did not stick apparently they didn't keep the oil inside either, LOL. Was later that night while reassembling that I realized I was out of...

Brian, I haven't made plans with anyone. I just wanted Phil to know Milestone wasn't closed. Having said that, I'm planning on going there tomorrow. I usually arrive around 10/10:30. I'll be trying a new bike carrier on my big ass van so I'll be hard to miss (silver extended length...

That's my plan. I didn't see anything about the main track on their website, but it'll just mean the vet track will be a bit more busy.

Milestone is NEVER closed! LOL. I'm thinking of going tomorrow to break-in the KTMaha.

Wow, Honcho's comments got me thinking . . . . . . that means late nights researching for at least a week! LOL. Thermally coupling the negative cell ends (the one area of a 18650 cell that's can support halfway decent heat transfer, relatively speaking) while maintaining electrical isolation is...

My Alta's still apart but my latest project is almost done. YZ167 with WP/KTM swingarm/wheels/suspension. My KTMaha I call it. Just finishing the machine work on the cases and it'll be all simple assembly after that. Hope to have it running so I can join the fun Weds.

You better have lots of money! I contacted the ABC manager (via LinkedIn) and said I had a quarter Mil to invest. Crickets . . . . .

Some paragraphs from my 2017 technical review. Although I've revised my detailed assessment regarding a few specifics my investigation opened my eyes on just how far electric motor and motor control technology has come in a relative short period of time and it's also absolutely clear that we've...

I didn't read (comprehend) the entire application, however, I've noted the following in my previous posts. The "emergency overpressure vent" located at the negative end of the cell (which basically ruptures the cells canister) is exposed to a small open area which is then open to a small...

I spent about three months running ANSYS transient thermal simulations on my CAD model of the Alta battery pack. First a few caveats; There's little data on general thermal transport properties of the 18650 cell, particularly at or near maximum discharge rates (non-steady state). The required...

A class action preventing Alta from disposing warrantee related parts or IP prior to making warrantee claims whole might be appropriate. Those with claims should get something going and I'd be willing to support ($$$) that effort.

On the flipside, IF you were the principles at Alta AND discovered/developed/utilized some new tech that eliminated many of the main complaints (range, weight, thermal limiting) BUT said tech was incompatible with much of their production platform making them essentially obsolete AND you were...

During the Slam Fest at Milestone it was over 100 degrees. Matt Cerami (the A rider racing my bike that day) reported that he smelled something strange during the last practice session. He even pulled off the track twice to investigate but couldn't isolate the smell. He said it wasn't like...

I ran into one of EV West's projects at this years Slam Fest at Milestone raceway. He had a converted YZ or CR something in the back of his truck. It looked pretty cobby compared to the Alta but he mentioned that the owner of EV West just started tinkering with full sized motorcycles and was...
