[Water Warrior 2]

Windshields, head buffeting and noise are all different to each rider and bike combo. A rule of thumb for the windshield is mount it initially in line with the forks. 2 parallel lines sort of thing. Helmet buffeting and noise is due to bike shape. rider shape, helmet shape, shield shape, and probably the phase of the moon. A full face helmet will catch a lot of noise from lower down on the bike(don't ask me how I know)so ear plugs are a must in most cases. Actually ear plugs should be mandatory when riding in my opinion. I did find a different helmet shape is sometimes quieter.
When we picked up the GZ I rode it home(probably 2 hours minimum)and never had a problem with buffeting or noise with a full face and earplugs, even on the highway. After a couple years and a windshield install I almost went crazy riding across town at lower speeds. The noise and lower wind blast was incredible. Lynda never had a problem. Go figure.
