Damn, for a new company they sure had old equipment. Probably just used for prototyping anyway. I'd give them $6k for the Haas VMC with the 4th axis. Having owned CNC machines from this era I can tell you they can be a major pain if you have electrical/electronic problems. The iron is...

Nope, just the items listed. Essentially a fixtured free-hand! I should have taken a picture.

I guess I didn't state it clearly. Yes, I machined the HUB, not the rotor. The counterbores you are probably seeing are for the rotor screws, that's the way this rotor comes. Look at the HUB and you'll see where I cut the hub (which is a flush surface stock). I used a counterbore, V block...

I can't believe (understand) how the cells could have self-discharged THAT MUCH in a couple of months. In general, Li-Ions are pretty darn good at holding charge when no loads are applied. Are you sure there are no sneak paths that the BMS couldn't circumvent? Anyway, I can't remember where I...

This is a pretty good source of information. The "white papers" are quite good. Li-Ion BMS - Lithium-Ion Battery Management Systems and large battery packs Pretty soon we'll be changing out cells like it was no more complicated than doing a top end on a two stroke (just more dangerous!)...

It's not the fact that the part failed but that it failed on a new bike. Contactor "welding" or sticking is typically a degenerative condition caused by repetition. If the vendors infant failure rate is 3/1000 then they're performing to spec I guess.

I got tired of buying KTM front wheels when using KTM triple clamps so I counterbored 3mm off the rotor ears. Now it'll work with both triples (using 3mm spacers with the Alta clamps). There's still plenty of thread engagement.

The fact that there's history of similar contactor problems on other electric bikes (not sure if it's the same part) is even more disturbing as Alta "should have known better". Also, even a proven part will be unreliable if it's mismatched to the system it's incorporated into. I'm no EV bike...

Why the heck would a brand new bike have a problems with the contactor? Packs yes, as we know there were some quality/process problems on the line, but this is a spec part. Contactors take a lot of abuse over time, but again it's a new bike! Bad parts from the vendor? If so, I suspect we'll...

When are you going to disassemble and see what they did?

That's a pisser, brand new bike. Based on a few other owners I'd say you have a bad wire bond inside the battery pack, possibly two! (a positive and negative fuse wire). All that means (if true) is that the electrical connection to at least one individual 18650 cell (out of over 500) is open...

What does gross sales have to do with providing a secondary source for parts, wouldn't you just need the unit sale numbers to determine demand (if any)? The bikes were expensive relatively speaking, but not enough to skew any forecasting model based on this market. Parts is parts.

Those step-ons step-offs were gnarly. What can you do with only 3/4 laps? Hardly any practice, short races, everyone riding down two classes, long day, guys crashing, bad gate pick, probably very frustrating. What surprised you the most and/or was the most enjoyable part of the experience?

Services like this open up whole new opportunities CNC machining in Los Angeles | 3D Hubs. You no longer need to invest thousands in machines and machine tooling (like I did) or learn to generate tool paths via CAM (like I had to). All you need is a desktop, a good CAD program, basic...

I'm only interested in the Laptop, throttle and a complete rear subsection (all 4 pieces). I need the laptop to complete my battery pack cooling mods and cell changeout procedure development work. TCMB371 and I are neighbors, so it's a double win as he can do the reverse engineering on the...

I'm confused! Other than that initial "window" for ordering parts from Alta, who's selling parts? I gather that Poskitt says he has parts but I've yet to see his inventory and asking prices. What am I missing?

The site of filming "supercrossed" the movie.

My main concern regarding anything electrical/electronic would be interchangeability. Specifically, would you need the Alta laptop to "reset" the system or get it to recognize a new component?

Just looked at this tread for the first time. I'm good for a race in Oct as it should be a bit cooler up there compared to SoCal that time of year! I've been racing since the late 60s so nothing should be new to me.

I'd probably replace the SDI upper cap with a very low profile cap and add a remote tank to re-establish proper gas volume. Might be able to add a tapered needle valve between the two to adjust the pressure differential somewhat like the Enzo subtanks do for forks. Another thought would be to...
