This isn't H2 but IS correct mounting: http://kawatriple.com/kh400a5/0576.jpg |

Mine must have the wrong mount then. It fouls the frame gusset when I try to mount it upwards, or the right way. If I could find some sort of dimensions I could make the mount, actually three thin plates. A center to center and bend angle would do it. |

Can you read the numbers on it? Mine has TPAR 772 among others... |

I didn't see any numbers on the mount, the whole horn was in rough shape. I think I will position it where it should sit and just make a bracket. |

Got the head pipes done. Finished the pipe layout, will make the first test one in mild steel sheet, then if it fits how I like it and forms well I will make them in 304 stainless. Looks like the two outer pipes can be identical, but the center one will be a bit tricky. |

I got the first mild steel test pipe hydroformed today. I thought it went pretty good, considering I have never tried it before. None of my welds split. it has two peaks I don't like where the diffuser cone meets the belly, so I will blend those in more on the stainless pipes. It straightened out a little so I will add some more bend early in the pipe. Also I noticed that the smaller parts of the pipe, the first part of the diffuser, were undersized to what they should be, I think it's because there is less press area to stretch out. So I will increase that portion. I did not need hardly 1000 psi to do it, I think you could form .050" stainless ok if you needed that. |

Amazing work! I should just quit now. Any updates on that long 3d print a few posts back? Just curious as to how it came out. |

Thanks. The 3D printed air box didn't complete, I have had problems with the printer and that one was longer than most so it uncovered what was wrong, the filament was binding in the feed tube so I totally changed all of that. I will split the box up into 4 sections now and glue them together, it was going to be a 2 piece. See if I can get that going this weekend. |
