Coming along nicely ... Wog made a set of headers to get the carbs moved forward out of the way of your knees ...

I have the regular carbs on my gl1100 and do not like the seating position with the original seat either. I am 6'3, long legs and flat footing the bike with my knees bent. Sitting upright, my spine takes the force of every pot hole.
I am considering a little more sporty position like in a Ducati Supersport, slightly leaning forward and elevate the seat.
Perhaps using the deck of a long board skate board with custom cut foam, or a piece of marine board.

Thats nutty! I love it though.

I've sourced the intakes from Randall, but worst case ontario I'll have to do the same thing. Obviously not quite as ridiculously, but an extra 2" of forward (While sitting on the bike) would make all the difference.

While spooling through Pinterest, I found a radiator guard which incorporates highway peg foot rests... That might be the solution for highway travel. In-town, it'd be slightly annoying but its manageable.

I'm going to be plopping K&N air filters to the carbs. I am unsure as towards how it will change the way my knees hit. I have a funny feeling it will resolve itself, as the tips of my knees hit the top of the velocity stacks... I think the angle of my knees will hit the tank before it hits the filter...

We'll find out once Canada Posts finds my package with my filters... :IDTS:

I've spent (most of my spending money) and the last few months building a 3D printer capable of printing high-strength demanding materials such as nylons, HDT nylons, carbon fiber infused nylons, polycarbonates, carbon fiber infused polycarbonates, and most importantly PEEK.

I've been designing my rim spacer along with an airbox for the weber 40 IDF carbs.

Weber 40 IDF Airbox
The airbox integrates a new trumpet design right into the box eliminating the need to source smaller trumpets, and shorter jet holders. In the photo is the design previous to the one I'll be using, but it's just small diameter changes and quality of life updates. In the photo as well I'm only using cheap crappy prototype material. The final print will be out of high-density nylon with about 14,000 PSI tensile strength. I originally opted for carbon fiber-infused nylon, but for this particular application, that material is way overkill.

The airbox design is meant to utilize the same air filter as this kit:

Between the integration of the trumpets to the box, lack of need to change the holders, and overall cost of production - the price has been dramatically reduced for what I'd consider a better product.

Rim Spacer/Brake Adapter Prototype
In the photos, these look a bit rough. This was one of the first proper 3d prints I tried, and didn't even consider the dimensional accuracy difference between CNC milling and FDM extrusion. Needless to say, FDM is quite accurate, but nowhere near as accurate as a CNC mill. I had to do a bit of rubber mallet hammering to get everything to fit, and although I'd consider it a successful prototype I'm going to be playing around a bit before I send off to get machined. So far - looks very good.
