As always Don products from F4 Customs windshield are excellent. I have a quick question for someone that installed the windshield in their F3. When I removed the original screw, it had a black rubber washer. Do I use the black rubber washer with the white bushing the windshield came with? Any suggestions will be appreciated. If I dont get an answer, I will contact Don office to ask. UPS delivered the windshield so late in the evening, and Don office was closed. Btw the tinted windshield looks great on my bike. See the pic below.
