thanks for the responses.
I tried your explanation Coconut, but it didn't work, I'll try again.

Now I have to wait for new front fork seals, because the left leg is leaking a lot of oil. I also ordered the Seal mate, but I think the sealing ring is already too worn because the oil is running out quickly.
So stop driving until this is resolved.
As for the battery, I will measure the battery and clean the contact points, then the battery will be out of the engine for at least 10 minutes.
