Monza/Le Mans-inspired V9 Project

Reading this article and seeing a video about this build they had to modify the rear drive somehow, which is not clear, but it wasn't a bolt on job.

Yeah, I spoke with him briefly yesterday. He said it was the only part they had to make from scratch for their builds.

Great looking bike, really love how it came out!

What did you do regarding the fuel pump etc? Is everything external now or did you modify the Monza tank?

I bought a used external system off an early 00s EV big block. The one I bought had the regulator that runs inline with the pump and filter, but then I bought a tank-fitted regulator and placed on the right side petcock fitting. Using a high-flow manual petcock on the left.

I’d love to install an in-tank setup. Maybe one day, but I don’t know if I can avoid the internally welded nuts part. Might have to bite the bullet there.

BTW, big shout-out to Charlie @ Antietam Classic Cycle for helping me LOADS with the fueling system.

I wonder if pop rivet captive nuts (blind rivet nuts) would be a good alternative - easier than welding? There are versions with an integrated seal.

RIVET NUTS ARE A THING!? With a seal, that could indeed be an enticing option.

I assume these ones are expensive:

Shop around. 

IF the fuel pump flange seal fits around the perimeter, outside the retaining bolt holes, then you'd likely get away with not needing the sealed rivet nuts. You may get dribbles of fuel sitting in the flange void though. YMMV
A while back, I bought a boxed assortment from AliXpress, for my various farkles. Non-specific/generic rivet nuts tend to have a larger minimum contact area though i.e. the material thickness that you want to attach them to.
