found creak the culprit was seat post. I took regular grease on a popsicle stick and put as far down as possible then cleaned clamping area then add carbon grease all over the seat post stem covered it put in post put lube on clamp and bolt tightened and no more creak. Before this i removed seat and post and took it for a spin. I would try this before anything else.
i also turned clamp around but not sure if i should have when i got it the bolt was closer to handlebars i just spun it 180.
