The hole fr the plastic trim may be strong enough depending on how much weight it needs to support. If it just has to hold something still it may be strong enough. You could always drill it out larger and tap it so it accepts a larger bolt.

Or you could drill them out and install a long hardened bolt all the way through the frame. I think you be supprised at the breaking strength (tensile strength) of a grade 8 1/4 inch bolt.

Having bent more than one frame in the same area, I would be really nervous about removing any material around stress points. That makes using existing holes and/or tapping them out sound a lot safer than making a new hole in a non-reinforced area. Safety before beauty. I'm not personally inclined toward farings, so for me it's a moot point.

Do you have the main mounting bracket from HD? That might be able to be modified to work or be a source of inspiration. BTW, that's some crack in your garage floor.

The next time you take the tank off it will be easy. Personally I dont think I would be drilling any holes in the frame. Cant you use the front downtubes or the crash bars to mount a bracket for the fairing ? The plastic covers are cosmetic, just there to clean up the look of the frame neck and protect cables etc.
I would think the holes that hold them on are small, 6mm or less ? |

While I think there is a bit of paranoia about drilling on the frame (think choppers, compared to these frames) I wouldn't use those little bolts, definitely get grade 8 if you use those holes. Can you fab up something to go across the backbone and utilize that large tank bolt? That won't go anywhere.

ponch --- I dislike the way risers look. I'll find some apes by spring.
My original intent was to drill holes through the frame then have someone weld steel tubing (I.D. same size as the bolts) in the holes thinking that would keep the frame as strong as new. Someone suggested I might be trying to over engineer it. I have no problem drilling out the holes for the covers. Actually a grand idea as then I would know that those 2 holes would line up. I had considered drilling a couple holes in the down tubes but they're round(ish) so I wasn't sure I could get a solid mount. The only problem with welding tubes to the frame is that I'd need to find someone to come to my house to do the work. I'll do that if it's necessary but if I can safely get away withOUT that, I'm good. I can unbolt something and bolt it back in place (generally without a lot of "extra" parts) but I'm not so good at fabricating stuff. cocheese --- Someone (krash?) already suggested utilizing the front tank bolt. I want to run the wiring inside the mount so the top needs to be covered. Not sure how I could get a bracket over everthing without removing the forks, triple trees, bars, etc. It's just not worth all that. If you (or anyone) can think of a suggestion, PLEASE let me know. I'd much rather use existing holes, bolts, mounts than drill anything (other than possibly drilling out the cover holes). Less work, less cost, less chance of mismeasuring, less chance of rust, less chance of......etc.

It looks like Kawa drilled the holes, inserted bungs, and welded them in there to tap. If you drill them I would not go too much larger. If you did drill, I would get one large grade 8 bolt to go through the whole assembly and put a nut on the other side so as not to depend on the the thickness and threads of the tapped frame.

I see what you're saying, cocheese. I think I need a center brace that will hold up the fairing all by itself which would require 2 points of connection. I could drill this hole out to 3/8ths or 1/2" and drill another behind it the same size. At least I'd know that MaKaw designed the frame for one of the holes. I'd like to think that once I painted the bracket black, it would be nearly invisible. Too many extra nuts, bolts, etc would detract from the looks. I'm sure I can get safety, functionality and looks all together.
The other consideration is wiring. HD ran the Tour Glide wiring down the side of the original bracket. I understand that most people won't even look inside the fairing but I will. HD got smart(er) on the Road Glide and ran the wiring inside the main bracket.

Not the Nomad . . . Previous machines. I've been riding since 10 y.o.a. not always responsibly. I'm not the only wreck in the deal.

I think I figured out a main mount today. Front/sides one piece with 2 bends then a top and bottom welded on mainly for strength. I'll drill out the top hole(s) for the corner covers then I'll only have to drill one more set of holes (one on each side) for a second bolt. (I'll put a bolt all the way through each pair of holes.) What do you think?

I don't think that corrugated paper is strong enough to hold a fairing solidly, and if it ever gets wet....
