Like the tittle says after 50mph my front wheel shakes bad, I can see the front forks bouncing up and down, the tires are in OK shape, a little dry rott but nothing to bad, I have it set at 28psi per the sticker on the forks, they are Yokohama tires and I have spoke wheels, (like a bicycle) there is no play anywhere, like a bad bearing or loose parts. Also I plan on getting a new tire up front I understand if I have spoke wheels I also have an inner tube? Is there a way to keep my wheels and not use a inner tube? Where can I buy a tire and inner tube package, if I have to go that route, like I said tire is OK, plenty of tread just old..
