    Stark weird noise and no crawl/ reverse... Drive train not reacting to throttle inputs

    From what I've understood and from your pictures above, your system should be the type which self bleeds: New genuine water pump kit for self bleed If I were in your shoes, before reinstalling the body kit, I would keep the bike on for a minute and then I would check the coolant level again.

    How Do You Plan To Survive (Battery) the Winter?

    TLDR: I think that we shouldn't be worried about condensation with low temperatures, but I'd like to share my thoughts to support my statement. A thought occurred to me today: when temperature drops, air can hold less moisture and therefore, if a space has been sealed at a certain temperature...

    Firmware not updating

    Read the description of the VCU in the spare parts list of their website then: VCU

    Firmware not updating

    Typically, according to the videos I've seen. when they overheat they start limiting power but they don't cut it. If you live where the temperature in these days don't exceed 70F, like I've read on the internet, it would really take someone at pro level to overheat the battery anyways. I'd...

    Firmware not updating

    Again, that's how it works now apparently, but up to some months ago it was the bike that needed to be brought to a place with 4G reception, since at least the gen 1 up to some time ago did have mobile service, and the phone had 4G connectivity, too. Back then, this topic was discussed multiple...

    Firmware not updating

    From what I have understood, now the updating process can happen through the phone, but initially, for example when I received my Varg, it was independent and the important thing was to bring the bike an not the phone to a place where there was a good 4G reception. If you have an older firmware...

    Stark weird noise and no crawl/ reverse... Drive train not reacting to throttle inputs

    That's true!!! I've just noticed, from one of your pictures above, that the connector of your gen 2 looks like the one of the gen 1. In their video tutorial, @9:25, they say that you are supposed to install and slightly tighten the front shaft but they don't say when and how much to tighten it...

    Throttle Stop

    It's not the first time that I hear something like this, for example an engineering professor once mentioned that some companies skip the last quality control step and just readily replace the product in case it malfunctions, because they have assessed that overall they save money in that way...

    Throttle Stop

    You can't demand that a company replaces a part only because you suspect that it's going to fail. So far they have been handling problems under warranty with a policy which is the most expensive for them, so personally I don't suspect that they will treat us badly after the warranty will have...

    Ryan Hughes talks about electric MX motorcycles

    Some years ago he said he had some fun on a Freeride: Half a year ago he didn't show hatred at all for electric MX bikes, he just said that there are cons with them: It sounds like recently he's changed his mind: Here is my comment to that last video, BTW. Sorry of the length of my comment...

    Ahah I like the pun. I agree.

    General Rawrr Mantis

    Last summer, while I was charging my Varg in between sessions in the parking lot of a track, I chatted a bit with a guy who was there with his son, who was riding a fuel injected 2 stroke KTM and he told me that there were some problems with updates of the ECU. I've also read, in some other...

    NEW! STARK VARG EX is here!

    A certain amount of power applied over an hour is just a way of expressing an amount of energy but it doesn't mean that the equipment that delivers and uses that energy is able to do that so quickly. If you have an amount of energy of 7.2 kwh, then you can produce, for example, 7.2 kw for an...

    Brembo 10mm LHB - Flex lever

    I have always been having the Formula master cylinder, installed inward on the handlebar and used only with my index finger, pulling the lever at about 3/4 of its lenght. I am a slow motocross rider. I do train my index fingers a bit using grip strengthener in my routine. Here is my review: •...

    Stark weird noise and no crawl/ reverse... Drive train not reacting to throttle inputs

    I suggest that you make sure to know how to properly disconnect the battery power plug. Remembering that I am not a professional techincian, here is what I know: Since people with a gen 1 battery should use a conversion kit for the gen 2 motor, I suspect that the High Voltage InterLock...

    NEW! STARK VARG EX is here!

    Same voltage, but not same power. 50 cells in parallel will produce 50 times more current than a single one, so in theory, given the same conditions like work duration and temperature, the maximum power that you can get from those cells should also be 50 times higher, since power depends on both...

    Outside warranty window

    Another thing that occurs to me is that Stark has stressed how they care about the environment multiple times and in multiple ways: according to the very first pages of the Varg manual, their main goal is to change the motorcycle industry by showing how it can be sustainable, the circle in the...

    Outside warranty window

    What you are talking about is basically planned obsolescence, which I believe is something real and implemented by many companies, even the reputable ones, but I think not by Stark, that I trust. Since our bikes are connected to the internet and can be remotely controlled and updated by Stark...

    NEW! STARK VARG EX is here!

    Still assuming that the EX uses P50Bs, here are the datasheets of the two cell types: P50B P45B Some interesting improvements: • Maximum charge current before 70°C cutoff: from 13.5 A to 25 A: if there will be fast chargers, I guess the 50s should charge faster. • Minimum charging temperatures...

    Redline Arenacross in Florida (e-bikes) + John Hill on a Surron

    Well, there has been some excitement after all from the not so many spectators. I would still like to see world class riders racing electric MX bikes; surely there would be more excitement, unless the stupid hatred of some people wastes it. It also seems to me that the e-motorcycles race showed...
