I would put the saddle back where it was ... if you need a handlebar / stem adj, dont try to take a short cut and move the seat to make up for it. you will just create more problems ...

Ex.: if the stem is too long, instead of getting a shorter stem, you move the saddle forward.

I would ( re)center and (re)level tha saddle, and go for another ride ... if you want a stem riser (30$), it IS, an option... if it looks like you will need a longer front brake cable (3$) and longer housing (2$/ft) its totaly doable ... My LBS charges 10$ for re-runing cables and adj the brake.
