Good evening all!

Wanted to stop in and give some info on something I've been working on. I have a 1982 kz550 ltd, and I was working on the carbs and noticed some of the float bowl gaskets needed to be replaced.  The only replacements I could find were either a full rebuild kit, or $18 or so per gasket.  Not feeling like spending that much on gaskets, I decided to spend almost that much on TPU filament for my 3d printer that is fuel resistant and hopefully would withstand the heat and compression of the carb.  This was about seven months ago, and i have been running gaskets made with this filament on two of my carbs since then.  Just this week I swapped the other two so all four carbs are now running with these TPU gaskets.  Also I printed a gasket for my fuel cap that i have been running for the last seven months as well. 

Anyway I figured I would share my experience and see if anyone else has done something similar!  I am also attaching some photos of the prints.  If you have any questions just let me know!

Here is a video of the material:

My wife had a KZ550 at one time and I remember having a difficult time finding carb gaskets.  Your solution is elegant.

I have several restored bikes along with a 2006 Goldwing with a sidecar. My wife has a 2019 Suzuki DR 650 for on and off road.

Welcome to KZR davidthejr nice job and a quality first post. You could probably make some side cash from some members here.

Indeed, 3D printed float-bowl gaskets are an alternative!

On my recent 1000R "Tribute" build, I too printed the gaskets for the Mikuni BS34 carbs, and also the pilot jet caps (not many carbs have these)
I used a slightly softer material called TPE, Thermo Plastic Elastomer.
I have also printed a petcock seal for a friend and the gascap seal on my bulid.

I am in the process of designing the seals for tips of the four choke plungers, and the little "concertina" type external seals on the plunger shafts.

Oh, and welcome to the Forum!
