Angry Mufler Removal Help

I did the 900rr head pipe swap on my 919. I put a Leo Vince can on the bike. Today I was trying to remove the can to rework my bracket mount and I have a problem. The can has the bolts attached to it, and nuts are used to screw on and attach it. Whatever was holding the threated part (I assume a bolt) has come unattached. So I now have a partially unthreaded nut that cannot be removed or retightened.

Anyone got any ideas? I am waiting for the Leo Vince reps to call me back and I figured this forum is a better source of knowledge.

Thanks for anything you got.

This is the best I have from my cell phone. It appears there is a bolt with a flat head on the mufler side. I imagine that it was once attached with a weld.

Sounds to be stripped. wedge a large flat Screw driver between the flanges to apply pressure to the nut and bolt and then try to back it out.

Ripper,

+1. Thanks for the idea. It worked, with a lot of effort. Now I gotta see if the company I bought if from, or Leo Vince, will do something to make this right. What a pain in the butt.

Is there enough room for a nut-splitter, the one with the flat head tip, not the one with the point?

That cutting torch in the picture seems to lack the focus necessary for the job.

My trusty Bic doesn't do much towards cutting. But with my phone at the right angle, it makes a decent flash.

Turns out that the bolt has a flat head. There is no stripping of the threads, although they looked better before I got the nut off.

For what its worth:

I would recommend staying away from Leo Vince. The mufler was bought of Ebay from Parts411.com. Leo Vince wont deal with it at all because of the ebay issue. Thankfully the Parts411 place has made a deal with their distributor to handle the warranty swap. It'll be awhile before I get it back, but at least the company is trying to help, where the manufacturer won't even discuss it.

I bet I buy another can and sell the Leo Vince when, and if I ever get another one in the mail.

FWIW: Most manufacturers will not deal directly with the general public. All warranty issues/defects are handled through distributors or aftermarket sellers. I would not sell Leo Vince short. I'm betting Parts411 will make good with a replacement can.

Aw come on man! It's a simple stripped thread. Happens all the time. Learn to deal with it and get yourself some taps, dies, PB Blaster and Helicoils.

I plan to die young, as late as possible.

Its not a stripped thread. It's a broke tack weld on a flat head bolt. The head of the bolt is sitting between the end of the mufler and the flange welded on the mufler.

I can deal with stripped threads, and tapping a hole. I am not capable of removing a welded flange, replacing the bolt, and rewelding bolth the bolt in place and the flange back on. But otherwise I bet a die and helicoil would work well.

Oh, my bad!
Still, I find myself re-engineering all sorts of things. Of course, it doesn’t hurt that I'm a machinist with an engineering background.
Point is, most things are sub-par if you look really closely. All too often, you don't have to look, it finds you.
Use the experience to shore up your skills. Many times, you only learn to do a skilled task when the option is to deal with manufacturers (or sellers), pay someone else, or pick someone’s brain (or all of us) to gain the know-how and tackle these things on your own.
There's no feeling in the world that compares to the enjoyment of out-doing the so called "professionals".

I plan to die young, as late as possible.

I agree with what you are saying, to the tee. That's half the reason I did the 900rr header, just to see if I could. As far as the can, if I knew a welder where I live, I might be in a position to tack the bolt in place from the front. But it would have to be perfect not to interfere with the fit to the head pipe.

Now lets pretend I had access to the tools. I would cut the flange off, shorten the can, weld a an inch long pipe between can and flange and use regular bolts. But that would cost me way more than the $15 to ship it back to the supplier.
