Ok I bought a 93 GL1500 and it has a MPA tire on the front and is running in reverse order. What I have noticed is a real bad buzzing in the handle bars almost feels like a bad wheel bearing. Took tire off and I see the out sides have some cupping and the wheel bearings were bad. So I replaced the wheel bearings and rebuilt the front forks and put the front tire back on and still have that annoying feeling and noise out of the front tire. I was wondering if I replace the front tire with a BT-45 130/70-18 will that buzzing go away. Thanks for any input on this.
