This is mine.  Yours.   This says your header sits too high for the rear for sure.  Mine for reference. They sit flush with one another.  | ||

Yep that's what I recall it looking like... Sadly after heating it thuroughly and bending it back into nearly the right place. Verified by installing and inspecting the ends being dang close to flush I let it cool naturally and it retracted back up | ||

Loosen all 4 flange nuts, try rotating it some since there's a tiny bit of play there and see if it will line up that way. Another possible option is to open up the flange bolt holes a tiny bit for more rotation. (Message edited by d_adams on April 24, 2012) | ||

Yeah I thought about opening up the holes | ||

I've heard of termotape warp pipes in XB | ||

I think this was more related to me modding the OE can and not supporting it correctly putting upward pressure on it. | ||

This is what I told you about the other day. Stock header at the flange is 1.25" (30 mm) so I'm going to up it a bit. It looks like it will be entertaining trying to make this size fit. It's 1.5" or 38.1 mm.   | ||

Looks beautiful. I'd offer a test bike but.... | ||

it'll be tight dean, but that's the challenge  this one was 1 3/8"  are those do-nuts from pro-werks? (Message edited by albert666 on April 25, 2012) | ||
| D_adams |
Yeah, they are and I think they'll work ok. The tightest available radius I found so far (besides the donuts) was 2.25" or thereabouts. I'd like it a bit smaller if I can get it. They're a little pricey at $100 a pop, so I only bought 4 for now. Should be enough to make a few sets if I get carried away with this. I looked for mandrel bent metric tubing a little, but it's not something widely carried over here I guess. I kinda wish I had my own cnc mill here, the guy I asked to make the flanges is taking his sweet time. I almost think I could have done them on a manual mill by now and I'm not a machinist. | ||

DA - for mock-up find someone with a H2O jet - then if need be go to the CNC | ||

dean i had 4 header flanges laser cut over here for £8 each the first ones i made manually i have £500 worth of bends sat here since january waiting for time to get on with some more, too many other things to do, be cool to see what you come up with  | ||
