Intake manifold Rotax123 - VHSB 34

thingiverse

For 2 stroke engine Rotax 123 with Dell'Orto VHSB 34 carburetor. This is my design for the intake for 2 stroke engine Rotax 123 with Dell'Orto VHSB 34 carburetor. I needed it because the original one had some leaks and buying it would have cost over 50€. In this way I've only spent 3.3€ and I can modify the design to optimise the efficiency. I've used a TPU filament which resist at temperatures of 100 degrees and I must say, till now, it hasn't gave me any sort of problem in my go-kart. The total weight is of 80g and I've printed it in two parts which will then be glued togheter with some special silicon thanks to the appropriate channels you see in the sections. If you have any suggestion please write them in the comments! Also if you would like another particular intake design write in the comments and I'll see what I can do.
