Anyone had similar experiance or a way to fix it? Let me know!

Did you replace the stem when you did the build...or is the stem very short? Sometimes, a short stem - which puts the handlebar clamp behind the front hub can cause shimmying motion when you ride. If this is in fact the problem, you may notice a similar shimmying when you get th bike up to higher speeds - 20mph or so.
