If it is mustahab to recite(from memory) withwudhu then would it be makrooh to do so with out wudhu?.

Praise be to Allaah.
There is nothing wrong with reciting Qur'aan in a state of minor
impurity (without wudoo'), and some of the scholars havestated that
there is consensus on its permissibility. There are saheeh hadeeths
concerning this matter which demonstrate that itis not necessary to do
wudoo' if one wants to recite Qur'aan and is in a state of minor
impurity. Rather the difference of scholarly opinion has to do with
touching the Qur'aan and whether one who is in a state of major
impurity (janaabah) can recite it; the majority of scholars are of the
view that both of these mattersare not allowed.
It was narrated from 'Abd-Allaah ibn 'Abbaas (may Allah be pleased
with him) that that he stayed one night with Maymoonah, the Mother of
the Believers, who was his maternal aunt. I lay down across the width
of the mattress and the Messenger of Allaah (blessings and peace of
Allah be upon him) and his wife lay along its length. The Messenger of
Allaah (blessings and peace of Allah be upon him) slept until halfway
through the night, or just before or after that. The Messenger of
Allaah (blessings and peace of Allah be upon him) woke up and started
wiping thesleep from his face with his hand. Then he recited the last
ten verses of Soorat Aal 'Imraan, then he got up and went to a
waterskin that was hanging there, and did wudoo' from it and did it
well, then he stood and prayed.
Narrated by al-Bukhaari, 4295; Muslim, 763
Imam al-Bukhaari included this hadeeth in a chapter entitled: Chapter
on Reciting Qur'aan after Minor Impurity and otherwise.
Ibn 'Abd al-Barr (may Allah have mercy on him) said:
This indicates that Qur'aanmay be recited without wudoo', because he
slept for a long time, so there isno question that he woke up without
wudoo'; then he woke up and recited Qur'aan before he did wudoo', then
he did wudoo' after that and prayed.

Al-Nawawi (may Allah have mercy on him) said:
This indicates that it is permissible for one who isin a state of
minor impurity to recite Qur'aan;this is the consensus of the Muslims.
