Though I believe drilling is required, then insert the rubber grommets from the standard hood. Then put on whatever windshield you would like that fits the G4
I put this on. U have to drill the holes. Was little nerve racking to drill holes in hood. But would guess u could do the same but with windshield and whatever base plate it takes.
Hope that helps. Can get install instructions, templates for holes, etc.
I was told the medium which fits after drilling and installing grommets is back order till like march. I run the tiny windshield and I also have one of the old not available anymore 1 piece ones.
crappy pic of the windshield but this is what I run when its cold
Part Preparation for Light Hood Equipped Models
NOTE: For installation on lightweight hood equipped models (one-piece hood), you will need to order three (3) grommets (P/N 517303756) to perform installation of a low windshield OR wind deflector.
