This would actually work, and here's why: Stark limits US-spec bikes to roughly 1,500W when charging on 120V. But if you step up to 240V (which is the actual US standard, not 220V), the math changes significantly — 240V × 10A = 2,400W before losses. Even accounting for transformer inefficiency...

If it’s the charger that comes with the bike, it absolutely does not use a neutral when it’s plugged into 240. If it’s the original MX, then they use the green wire on the cord for one of the hot legs and they use the black wire on the cord for ground ha ha ha ha so just keep that in mind. The...

I have a 2018 YZ250F QS138v90 and an Amorage 21S 75AH. And a Votol EM260S? (I think) controller which is the weak point. The EBMX V9000 barely fits behind the rear shock. A little too long. I have the EBMX x9000v1 installed on my Sur-Ron with a EBMX 20S 42AH 72V battery 6AWG Battery wires and...

I have a YZ250Fwith a QS 138V 90 and a 75AH 21S Samsung50E battery L shaped; yes it is top heavy. I also have an Alta MXR and a Varg MX. All three are heavy to pick up. but the YZ is smaller than 30 pounds lighter and easier to throw around for sure on a trail. I could be imagining things, but...

I need a working display. Mine does not toggle miles/hours

Got my kickstand on Ebay from Liquid Performance. Message them if you don’t see the listing, the kickstand is super nice quality compared to a Varg. It uses coaxial springs within the kickstand leg. As if a bunch of California engineers thought about it for a long time :)

the 6-pin connectors and pinout are different (Stark is a JST-JWPF and the Alta is a connecter I don't recognize they use on their harness) - I am hopeful and it seems logical that Hirschmann would make the same throttle for both. I documented the Alta pinout. Plan on testing the Stark throttle...

Not well. Heart rate reached 200BPM. I thought i was dying. The worst part was receiving a polyester T-Shirt from the contest sponsor a month later. I hate polyester.

did 99 laps (1-1/2hr constant) in 105degree heat (LitPro contest) The bike acted normally.

In my experience, that aux power outlet has a super narrow window of min to max power and if outside those points the ACP will shut down the bike. Short answer after a ton of aggravation: “don’t touch it” :) But if u insist then definitely change the super crappy connector they chose, the...

Excellent documentation. I hope that helps somebody. I made my MXR street legal by adding the front and rear wiring harness and installing stock rear lighting and brackets. Never found the black plastic decorative “tail” so was forced to fab one out of carbon fiber. Used a Baja Squadron...

If I recall correctly, my Varg charge monitor consistently displays current power at 3100 watts even though I set it to the max 3300 watts... so unless they do not include other things that get power like the computers and the cooling fan, etc... 3100Watts / 240VAC = 12.91 Amps.

I got the Briggs & Stratton QS6500 lots of Alta owners recommended (not sold in CA so I bought it used, had it shipped, and threw a few hundred into it to bring it back up to factory specs and added a mechanical hour meter). ~100bs and charges the Varg at full power at 50% load. If I ever have...

Update- disassembled the throttle and the potentiometer is sealed plastic with the wires glued in Silastic. I’ll call them and ask if these parts are sold separately (would be stunned if yes) before buying another throttle.

It’s more a question of: who didn’t receive an improperly wired cable and plug. Seems that all of them with hand wired cord caps used the wrong color code wires and improperly attached cord cap. The chances of Alta allowing that nonsense were probably zero.
