+1 ! When I first heard it in videos I thought "omg, no way!", but after experiencing it in person I'm hooked. It's like riding a frantic cartoon robot. :)

Thanks for that! Always great to have a real-world positive review, especially of a mainly-dirt-bike dealer. I live near Danbury, used to drive up to Portsmouth to the cable depot there - not a bad drive, looping north around Boston. Yeah, if the sales tax is avoidable I'll do that in a flash.

I'd rather have Stark give me the ability to diagnose the issue (i.e.. documentation; yeah right, jk!), then I'll decide who should do the work (i.e., shoulder the responsibility for the repair and its outcome). The Stark will be my 5th e-MC rodeo, and I've got a pretty good idea now of what I...

Around the time the Stark site first appeared, I remember reading the features paragraphs and thinking, "I really should save this in case it disappears", but of course never did. :( I recall the features being separated into an upper-paragraph 'standard' group (mostly bike adjustability / ride...

Sometimes that first 'word' on the LV circuitry can be a real day-ruiner, if it's a charged-cap spike or similar. :) I wonder if Stark will provide even block diagrams of the electronics.

Exactly what I do with my Alta's charger. And remember... smart things are stupid when they're dead (no power applied). :) I love these things, use several different-switch-location versions of them all over the house now.

When I finally get my Stark, I'm planning on buying a KTM p/n79202030044 9mm-piston clutch lever, from a place that accepts returns. :). I finally found the following on TT: "the 79202030044 lever replacement piston kit is listed as REP. KIT PISTON 9MM, probably a 9 mm)", which is as close to a...

For every power-supply type device I use, I always connect the load (unit to be powered/charged/etc.) to the device, then the device to AC power. A few instances of small bzzaps! followed by dead load units was all it took. :)

How Oh OK, now I get it - thanks for the clarification. Wow, I guess bad firmware updates could maybe fry a lot of stuff on the bike.

How exactly does this happen? The battery firmware is faulty, and then cannot be overwritten or rolled back after updating? This happened to at least one e-MC manufacturer I know of.

If your Stark AC-power plugs had their ground wires connected to the US-120V neutral (longer US-outlet slot) but were otherwise correct, you'd get the symptoms you describe (no 120V operation, 240V OK except for 'tingling' on charger chassis). Idk about the Stark's, but some plastics are very...

Maybe the entire cooling system comes off as a unit, and is then disassembled? I have 3 photos to guess from, none of them good.

Magnesium is kind of a reactive metal, and doesn't always play well with others. Many of the first Honda liquid-cooled CR mag. RH side cases/pump housings were eaten away fairly quickly, and apparently it doesn't really like ethanol or any of the alcohols much either. There are various...

I think the motor too. 600cc coolant (Alta is 720cc).

Thanks for the suggestions! I was thinking mainly of targeted heat reduction focused on the Stark battery case only, using compact pre-assembled 'cooling stands' that could be moved quickly into place each side of the bike. The Peltier units would be pre-installed on the battery case with a...

I added this post looking at various cooling options to the 'Battery Cooling' thread in Electric Powertrain.

I was going to start a new thread of this name, but there already was one w/lots of good info. It's cool the title's all-inclusive, lots of different batteries in use here at EDR/AOF. I'm no thermo expert, but having twice slogged through the 1.3K+ pages of the Heat Transfer Handbook...

My post was aimed at improving the Stark battery's cooling, not hi-output electric motors or anything else. And I'll take 'ok' over thermal limiting at 7m any day of the week. :)

It's too bad the soak-it-or-smoke-it mentality has completely dominated MC cooling methods. I remember forced-air cooling working pretty damn well on all sorts of stuff from Volkswagens to CPU's, guess those days are over (BIG delta-T or nothing!!).

Yes! and it worked perfectly after charging
