(And no, I didn't crash.) |

| Je Fa Fa | was there a weld there? if so, poor welding? looks like it might be a 2 piece design (for engine removal), but that triangle piece is what is the issue....if so, it should be a much easier fix than you're thinking. |

| Licensed Joined: Dec 2010 From: Portland, OR I Ride: 1979 Honda CB750K | I've definitely looked over this bike in depth, several times. I check it every few weeks. It's an old bike. They need extra attention. Also, my friends with old bikes have looked it over. Also, the shops i've been to. Also, Tues Night Coffee people. There's no way we could have all missed it. There is no rust at the breakpoint. It's new. And no, it's not supposed to be like that. It's not a 2 pc frame ;o) Here is the other side, one solid frame pipe: ![]() The engine mount is on both sides of each downtube of the frame (Aka: 2 mounts per downtube) Then the crash bar mounts onto the engine mount. There was no welding there from before i bought the bike. I mean, there's a slim possibility that i never noticed a critical weld on the frame of my bike. But, i've examined the bike over and over. :o\ Either way, to fix the frame, replace the frame, or part it out, i have to completely teardown the bike. {sigh} Might go for something a little more modern. |

Edit* can you shoot a pic of what it looks like from the front? If anything, have it welded, between the weld and that fancy get up holding it together I'd ride it. Last edited by 1shinysideup; 08-23-2011 at 03:39 PM.. | |

| Je Fa Fa | piece 2 is the piece you think is broken. but piece 4 the piece you should make sure is fine. if it's fine, it's fine. |

But, at the same time, the engine mount isn't supposed to be bent, and the pieces should probably be lined up, not offset the way they are. You can't see it from the angle of my pic, but the two frame pieces do not line up at all, when looking straight on. |

Nothing there looks bent other than factory bends. Maybe you should take it to a proffessional, one who knows what kind of "special care" your bike needs and let them make the assertion as to whats bent. | |
