Noticed a few members have changed the windshield from the original on the 07 Serk. Still waiting on word when mine will be built...
. but I am interested if the original shield was too small or if it caused buffeting problems? I also would like to know the correct HD part number for that , if needed , I could install using and retaining the detach mounts. Also what may be needed to add driving lamps that I believe I saw on Hoist's beauty
Might as well get a start on ideas just in case I see a bike this year.

The original is a wind screen and not a windshield. The hardware that comes with the OEM windscreen has 7 horizontal mounting holes. The windshield with hardware from HD has 5. You can use the OEM 7 hole hardware and order a Clearview windshield but you will need to specify to them that you want the 7 hole windshield. A lot of people are buying the 5 hole hardware with windshield from HD and ordering the 5 hole windshield from Clearview because of problems fitting windshield bags on the 7 hole hardware. Hope this helps. jj
