Juergen, great mini Genisis (lovely pipe too, I never had a real one) but I'm a bit confused:
The main tube for the genisis is 12/10 alu, with some 10mm rod press fit, yes? That is the yellow and orange in the pic above respectively?
Then the green is from the mouthpiece end and in this pic looks bigger:
What size is that tubing, 15/13 with a gap between the two? All sorts of inspiration here, sorry to pester
edit: I'm slow and oversizing LOL. Still curious about the mouthpiece tube size.
