I bought Marcels new 31" Stingray windshield and love it. He sent me a set of lowers that hug the tank line and attach to the bottom of the windshield. The problem is a loss of airflow through the vents at the bottom of the "tank". So I get an overwhelming smell of exhaust. I'm talking "headache" here. So I took them off. Up here in Wisconsin help with keeping warm is at a premium. What should I do? Drill holes? Cut pieces out? Anyone else have this problem? Bob.
