Hey you experienced Concours owners, educate me about windshield upgrades. I just got a new 2006 Concours last April and I love the bike. However, the stock windshield just doesn´t work for me unless I lean forward/down into the pocket. My back (53 yrs. old) begins to hurt if I ride in that position very long. I´m considering an upgrade approx. 3-4 inches taller with no curve on top. What is the consensus on a windshield upgrade?
