had all the wheels balanced (stock cast wheels) still have vibration on handle bar @50mph.
I really question your "balance". The word "Balance" is Very broad.
My question is How were they balanced. If I was fighting a problem like yours, I would find a local gas station that has an old Hunter wheel spinner. Just jack the bike a few inches off the ground and engage the spinner. You very well may be surprised how "balanced" your tire/wheel really is.
Most of these motorcycle shops use static bubble balance machines. They are hit & miss at best.
Track down a local Hunter or Bear spinner. Back before computers, that was state of the art. Those spinners were sold by the thousands. By itself it wont be able to balance your tire, but it will tell you under dynamic conditions how balanced your front wheel is.
Trust me on this.
