ok so i took my 05 S40 out last night on the freeway i got up to 60 ok but once i got to 65 and a little faster the front started to shack alittle on me. So im trying to find out if just something is out of aliment or if there is a design problam with the bike to couse this

Wobble can be real freaky.  What is different about your Savage40 from stock?

I really hope that you have experienced high speed wheel wobble.  Nothing like being forced to slow down, while feeling like you have absolutely no control over your bike or bowels.

It's that good!
8) ??? :'(

no the wabble is a side to side motion like the wheel is being turned as far as i know my bike is stock its also my first bike it has 1400 miles on it i dont know if it has or needs wheel weigths.....is this something i need to take to the dillership to get fixed....and i want to make sure this problam is not in the design of the bike cause i want to go on some bike runs with this thing

The "classic wheel wobble" which is even discussed in the MSF training program, is a side to side shaking of the front wheel and handlebars.  

It usually occurs only at a certain speed, and you can not steady the bars with your hands.  It is like some invisible gremlin is fighting you with the bars.

It starts slowly and picks up frequency if you continue accelerating.  Your only recourse is to slow down.  It is very unnerving.

My Yamaha 850 was prone to do this at about 70 and it was due to the dealer installed Windjammer fairing that was on it.  If I got caught in a particular kind of cross wind it could start.  But there are a few different reasons for woblle

It really is more related to the steering and alignment than the wheel.  It is not inherent to the Savage40 design, which is why I asked about changes to the bike.

Here is an interesting discussion about it.  Might give some ideas for where to look.

I haven't experienced wobble with or without my windshield on the Savage at 80 (which I know would be unnerving).  But that's not the point.

The wobble we are talking about is not induced by road conditions but the feel and effect is very similar to rain grooves.  The only difference is that rain grooves are obvious.

??? The only high speed wooble I have felt on my 06 S40, was when I would come up on an 18 wheeler, or when one would pass me.  But this was at around 65-70, and a Superbrace solved that.  It may seem as stated earlier, maybe a wheel weight or loose spokes.  For a very light weight bike, the Savage/S40 is a pretty stable bike.

That's called plain old buffeting.  It ain't the same thing.  At least when passing a truck, acceleration gets you through it.  

Wobble is another animal...and luckily not very common with the Savage either...or we'd be discussing it all the time
