Vul, I just looked on the Cruiser Customizing site at 1600's with the fatty's and the upper end of the guards terminate into the frame. On the 1500, the guard tubing runs continuous across the frame downtubes just above the radiator. So, there is more clearance on the 1600 for the wind deflectors. Anyway, I had already ordered the deflectors when I started this post and I received them yesterday and installed them. They do touch the engine guard by just ever so slightly when in full lock. When riding the bike I never really get into full lock so this slight bit of contact won't matter when riding. I think over the winter I will try to elongate the holes in the deflectors to move them just a bit forward to eliminate this contact. I wish I could find an engine guard that dead-ended in the downtubes of the frame like the 1600 Cobra does. I really don't care for the look of the chrome tubing of the guard running across the frame from one side to another.
