SEi muffler removal

Postby Rusty Bike » Tue Jun 07, 2016 8:23 pm



I have two leaky exhaust gaskets. These are the rear most ones that are between the muffler and collector. I would like to replace these without dropping the four pipes at the heads. I have a burning outfit so getting the bolts out of the clamps should go ok, plus I have new bolts. :roll: . I am removing the rear wheel for tire change, clean and lube so that will be out of the way. Any advise as to how to get the muffler assembly free of the pipes without destroying the other gaskets or causing any other damage. I feel this job may be a SOB!
Back yard engineering suggestions welcome. Thanks folks...Rusty

OK, no replies. After doing the required research I find that the best way to replace these gaskets may be to remove the header pipes only and leave the muffler assembly alone. Is this the way to go? Also, will I need to remove the crash bars? I'll be working on this today. Thanks folks, ride safe...Rusty

Haven't done this, but that might be the easiest way, or you have to drop rear wheel out of the way. Only reason to remove crash guard would be to get the pipes out or get to a bolt. By the way did you find replacement gaskets? When mine leaked the bolts had broke off, replaced bolts and used anti-seize (in case I ever want them off again :)

I've had the pipes off a few times on mine or another 1200, yes, you'll need to drop the front guards as I recall and loosen rear bolts above the mufflers, one each side and loosen those clamp bolts .... then lay down and remove nuts from studs under cyl heads, likely some studs will come out with nut. That's OK. When both sides are loose, front of pipe set will come down out of head and you can rotate and remove head pipes from muffler. The pipes seal to the head with copper rings up in the head, I've reused them several times.

Go easy when reinstalling the nuts and those studs with nuts on them as they do not have to super tight! Goood snug is good 'nuff.
