Bending the exhaust hanger

[PeoriaMac]

Bike: 1986 R80RT. PO had a tip-over, as we have all had at one time or another.
Result: RT fairing gouged into the tank and the left muffler gets pushed closer to the
rear wheel. It's not an operational problem, but I'm being anal about things lining up
the way they should. Besides, it might someday affect rear wheel removal.
My feeling is to use a dead hammer and pound (carefully) the exhaust carrier under the
left footpeg back into place.

Bad idea?? Other possibility...heating it with a torch before pounding/bending...

i have been told that some metals get weak when heated and bent

So you have Marty Feldman Pipes?

Heat it and bend it. Slow and easy. It beats the heck out of yanking on it. Can of Rustoleum will hide the burnt frame paint.....

Yes, yes I do. Thanks for the thoughts. Certainly cheaper than a MAC two into one....

Say, when you wash a bike, you REALLY wash it don't you?

I crashed my RT, right pipe bent badly outwards. A blacksmith used heat, but impossible to get it right. Metall weakened too.
So I got a new pipe holder ?¿ear?¿. A local welder took the old one out, put in the ?¿new?¿ used one. I sprayed on black paint. You can??t tell the differance.

This was a post crash wash after I removed most of the broken/bent things. I was one-armed at the time. In this case, my header pipes were squished and bent along with the support brackets between the frame and exhaust. Support brackets are cheap if that's what you are fighting.

Lesson learned: Never tear down a motorcycle when hopped up on pain medication. It's really difficult to remember how to put it back together.

The hanger gussets are probably already cracked, but pounding on them won't help matters. Cracks tend to start from the "battery vent tube" cut-out (nice of BMW to provide a "sensitivity notch" right from the factory).

Top arrow is pointing to the gusset where it is welded to the crosstube.
