Honda NSR50 carb spacer for original intake manifold with PZ16 carburetor

thingiverse

I'm on and off tinkering on my NSR50 project bike. I want it to be as stock as possible, but original carburetors are surprisingly hard to come by (or ridiculously expensive), so as a temporary solution I designed this custom spacer to allow a super cheap PZ16 carb (same inner diameter as the original one - 16mm) from AliExpress\* to be mounted to the original intake manifold. The bore of the PZ16 is slightly offset to the hole in the original intake manifold; this spacer balances this out. **Notes:** - The part fits, but I have not yet tested it! So … - … I don't know if it will hold up. I printed it in PETG and hope that the water cooling carries away enough of the engines heat. We'll see if this works. \* The quality of mine is actually really nice! **PS:** Fusion 360 source file included.
