Reception got kano overwhelming buhari says

I think there may be a slight mistake in your sentence. It seems like you meant to say "Reception got Kano overwhelming, Buhari says" instead of "reception got kano overwhelming buhari says".

If that's correct, here's a possible interpretation:

President Muhammadu Buhari has said that the reception he received in Kano, a state in northern Nigeria, was overwhelming. This could imply that the people of Kano gave him a warm welcome during his visit to the state, and that he was impressed by the enthusiasm and hospitality shown to him.

Please let me know if this is what you meant, or if you'd like me to clarify anything else!
