501fe 2001 fails after changing stator

The first hello everyone and thanks in advance if anyone can help me. I bought a 501 2001 for a year and I am in love. but a month ago I stopped giving spark and looking with a friend (I don't have much idea of ​​mechanics) we saw that it was the broken stator. I bought one used here in Spain and it looked different in the hand (in the old one the coils were not seen or the copper was all covered with a black plastic) but in which I bought everything is exposed. We have mounted it and now the motorcycle in first, second and third goes well to any revolution, but in fourth, fifth and sixth to open gas and want to be revolutionized ... fail, go fatal ..
I am trying to read your threads but I have no idea of ​​English and it costs me a lot even using the translator.
Could you help me a little, tell me x where should I start looking?
Thank you.

The stator carrying the motorcycle was like this.

used stator to buy and mount.

Thanks for answering! I asked the seller what resistance measure he gave him and he said:
red-black 2,910 oh / green-black 160 oh / yellow-blue 0.9 oh. Then I looked here in the forum and thought I understood that with those measures correct for my motorcycle, that's why I bought it.
So, a 1989-1998 stator also gives those measures?
Or the seller lied to me?
I mounted it without checking ohms because I have no device, but I did measure the charge that came to the battery and it was only 6.5v. I miss myself, but I thought I would have connected some wrong cable.
But if you tell me that it is not correct, I will have to throw it away and start over.
Again, thank you so much.

Hello! It is already solved, in the end it was not the stator, which is the right one and now the bike is going perfect. The problem was that I had clogged one of the carburetor's breathing tubes, so the motorcycle failed. I wanted to ask you another question that I have not seen in the forum, what is the "acceptable" consumption of oil on my motorcycle (fe 501 2001)? It consumes me about 150ml every 100km driving strong. I use motorex crosspower 10w50, would you recommend using another one? Or do you think I should open the engine and check? I am sorry to open it because the bike is perfect, fine, it sounds just like a clock and kicks at the first both cold and hot, and although everyone says yes that motorcycle, that year, if it is a ****, that if it gives problems ... I love it. The only bad thing is that I'm worried about that oil consumption ..
Thank you very much again, I thank you for wasting your time answering the questions.
THANKS!
