Alhazred Posted July 16, 2014 Share Posted July 16, 2014 The 2bros header I recently installed on my 4th gen is rubbing the swingarm ,when the suspension compresses I can feel it rub the header tube( I think it's the no.3 cylinder).I can't get even the smallest feeler gauge in there and I'm not sure what to do about it.Does anyone have any suggestions?

Member Contributer JZH Posted July 16, 2014 Member Contributer Share Posted July 16, 2014 Rubber mallet! Those headers can be tricky to install. Odds are something is not fully seated somewhere. This is my RC36 (3rd gen). Right-exit TBR. Ciao, Link to comment Share on other sites More sharing options...
Alhazred Posted July 16, 2014 Author Share Posted July 16, 2014 Wow that's a lot of space there,something is definitely wrong.I double checked everything today I guess I'll have to go through it again. Link to comment Share on other sites More sharing options...
Alhazred Posted July 16, 2014 Author Share Posted July 16, 2014 Can anyone confirm if the center stand mount needs to be filed down to fit a 3rd gen 2bros left exit header to a 4th gen? Pics coming... Link to comment Share on other sites More sharing options...
Alhazred Posted July 16, 2014 Author Share Posted July 16, 2014 I couldn't get a good shot here but this is where the header is rubbing the swing arm. Link to comment Share on other sites More sharing options...
Member Contributer Switchblade Posted July 16, 2014 Member Contributer Share Posted July 16, 2014 Does it have a bad exhaust leak ? If not I would have to say bad alignment in the jig at the factory. Link to comment Share on other sites More sharing options...
Alhazred Posted July 16, 2014 Author Share Posted July 16, 2014 No leak,if I put my hand over the outlet it will stall within seconds Link to comment Share on other sites More sharing options...
Member Contributer Switchblade Posted July 17, 2014 Member Contributer Share Posted July 17, 2014 Bad pipes I think ... Link to comment Share on other sites More sharing options...
Alhazred Posted July 17, 2014 Author Share Posted July 17, 2014 That would be a shame. I wonder if I could heat it up and bend it just a bit to get enough clearance. My other option would be to take some material off that center stand mount. Link to comment Share on other sites More sharing options...
Member Contributer Rush2112 Posted July 17, 2014 Member Contributer Share Posted July 17, 2014 I'm assuming you got them used... they could have been in a wreck and bent... or bent in storage. I'd try to ensure everything is installed correct and straight and if that didn't work some creative encouragement of the pipes with heat and force would be my next step...

Member Contributer gll429 Posted July 17, 2014 Member Contributer Share Posted July 17, 2014 did you replace the gaskets? loosen all bolts..shake the pipes like they owe you money .. tighten in a rocking pattern ..a little at a time on the rear headers. check if its better,, if not,, either shave the stand mount for whack the pipe with a ball peen hammer( pipe off the bike) to make room.

SEBSPEED Posted July 17, 2014 Share Posted July 17, 2014 Pelase review the pipes for any dents/dings and report back. They can definitely be moved around, let's determine if you're fighting any unusual circumstances first. I fitted a set to my 4th gen, after wrapping with DEI wrap, and they still have room.

Alhazred Posted July 17, 2014 Author Share Posted July 17, 2014 Bought it used,PO took it off his bike and sold it to me. Installed with new gaskets. I inspected it before buying and didn't see any damage,also took a few good looks before installing. I have it loosened up now,I'll give it a good shaking and see if anything will seat better. Right after I got it. Link to comment Share on other sites More sharing options...
Member Contributer Rush2112 Posted July 17, 2014 Member Contributer Share Posted July 17, 2014 Nice looking exhaust system... I'm jealous might be a silly question but is it possible to switch the rear header primaries? Could they be installed on the wrong cylinder?

Alhazred Posted July 17, 2014 Author Share Posted July 17, 2014 I don't think it would be possible to mix them up they are far too different in shape.But just for the sake of being thorough I have the one with the big bend on cyl no.3 or the right rear. I just took it off then re installed and came up with the same result. I'm going to file that mount down before trying to bend the header,I only need just a tiny bit of clearance.

SEBSPEED Posted July 17, 2014 Share Posted July 17, 2014 That said- you can shift the front tubes if you loosen them as well. Link to comment Share on other sites More sharing options...
Alhazred Posted July 17, 2014 Author Share Posted July 17, 2014 Well I took it off 4 times today trying to get it in place and it's better now,not perfect but better.I noticed when I tried tightening the offending primary with out the rest of the header on it would slowly pull into the swing arm as it tightened. I guess the only thing I can do now is heat it up and try to get it in shape that way. Link to comment Share on other sites More sharing options...
Member Contributer JZH Posted July 17, 2014 Member Contributer Share Posted July 17, 2014 Mine is a right-exit, so a completely different header, I'm afraid. TBR always said that the headers would not fit on a 3rd-gen with a center stand, but I'd never heard anything about having to modify or remove the mounting lugs. Pulling in one direction while being tightened says "bent tube" to me... Good luck. Ciao, Link to comment Share on other sites More sharing options...
Member Contributer gll429 Posted July 18, 2014 Member Contributer Share Posted July 18, 2014 look, these pipes are SO strong and everyone gets whiney about them.. even if you heat the sucker with a torch to orange hot and try to bend it . you wont do much. place a pry bar or a screwdriver in the offending spot and tighten the pipes.
