What was the state of charge (SOC) of the bike?
When you key 'ON' the bike does the battery LED turn on (blue led)?

Hello

The battery was 80% full charged... no the led
doesn’t turn on, nothing happens...

I blame @Rashid510 personally

ACM battery replacement....

Is that the little 9v battery?

Is that the little 9v battery?

Yes. And you must replace it with exactly the same Li battery or you will be replacing it again very soon.

 

[Mat Rebeaud]

No it s not the v9 battery! It’s main battery problem
The bike don’t even have 1hour ride

 

[Rashid510]

Checking the 9V allows us to see whether or not its a BCU problem (within the battery) or a ACM problem. Sometimes the 9V acts up. Hence the post. If the voltage is at 9V on the ACM battery then thats out of the way.

Most likely the BCU board in the battery has failed. There are ways to fix it. But being in Europe makes it more fun.
Could you provide the last three digits in the VIN?

(Also your picture is rotated the wrong way. Dunno if its the bike ahead or behind...looks like you did a battery swap)

There are BCU boards (v2) suitable for the MXR through Ebay. I would purchase one ASAP.

I had the same problem (assuming it is in fact a BCU failure), and it was quite an ordeal.
Luckily, had a lot of help from this forum's experts.

 

[Mat Rebeaud]

Yes the 9v was fine. And I switch battery from my old bike. And the new bike turn ON fine.
It s a battery problem...
And the bike don’t even have 1hour ride... lucky didn’t cut wen I was jumping...
@Rashid510 what is VIN number

 

[Mat Rebeaud]

[Rashid510]

It's a 17 digit s/n on the headtube.

That rear sub frame is really nice - do you have any information on how you made it, what plastic and seat did you use etc. I’ve been wanting to do the same thing

Since he has the battery out, do you want the battery serial number too?

Wow that’s a cool picture - I only can do that when I get bounced off in sand whoops - thanks

As others have stated you should by a battery BCU off eBay from liquid performance and you will also need new battery contractors from Gigavac as its is too hard o salvage them from your existing battery as they are epoxied in. I have a quote from Gigavac if you end up needing it

This KTM subframe look right
