Could you post a pic of what you have added?

I just happen to have the seat and tank off mine. This is what my dealer added and then I added a Shorai battery and haven’t had an issue one.

The first photo shows the new ground cable attached to the stator housing.
The second shows the other end of the cable connected up by the coil.
The 3rd is the “new” battery.

Thanks for the pics! Going to have to do that to mine next.

Mine was having a little trouble starting in gear on hills after stalling - spinning but not starting - so last night I put in a Skyrich/SSB 220cca battery & ran a dedicated earth from the starter mount to the battery -ive terminal.

Starter worked super-strong in gear on hills today - appears to be fixed.

How good is the suspension on these bikes? Superb.

So it is seeming that the starter cable upgrade, battery 220 cca upgrade and possibly the CDI re-map is fixing the problem. Is the e-start button now starting the bikes when cold or are you using the kick starter for the initial start and the e-start button for subsequent starts?

-5c bike was not started for a week. This is after the upgrades. https://www.youtube.com/watch?v=Gwu4ZiTYpf4

Thanks for the video. My 2018 spins the motor really well but it will never fire up when cold. I see you replaced the rotor too. Maybe that's the next problem to address. I will contact my dealer tomorrow.

I have a 18 EC250 and my dealer sended me a Skyrich 4Ah 240cca battery and a ground cable that runs from the battery to the startmotor bracket. And also a positive (red+) cable from battery to the starter relay and now it starts both hot and cold.
Before the upgrade it only started when the engine was hot and the battery was fully charged.

Is it a ground cabel the black that come with the battery?
I thought that it was a replace for the thiner + cabel to start engine.
