Trying to remove exhaust so I can take rear wheel off for new tire. Exhaust flange is stuck on studs. It moves to a point about 1/4 before the end of studs and gets stuck. I've wiggled, tapped, cussed and sweet talked it. Any ideas?

Are the mounting bolts for the exhaust removed? If not, loosen them to get more wiggle room. Maybe even take them out since you need to to get the exhaust off. Other than this, maybe squirt it again with Skunk Piss.

I've never had this problem, so I'm just guessing. Somebody who knows more will chime in eventually.

have you moved the flange as far down the down pipe as you can-- ie to where the weld is? from there it'll be clear of the studs. then you'll need to angle down the rear and pull down the front and twist it around to clear.

to be clear, it is a pain in the ass. but the flange has to be clear of the studs to even get started. I know it sounds counterintuitive but sometimes lifting the rear of the exhaust will tip the head pipe down and help clear the flange off the studs.

good luck!

The pipe isn't stuck. The flange won't come off of the studs. It will slide until it gets stuck about a 1/4" from clearing the ends of the studs. The pipe would come off if the flange would clear the studs.

angle the rear of the pipe up or down while gently pulling down on the head pipe and manipulating the flange. once the muffler securing bolts are removed the pipe wants to bind up on the studs due to the angle. a little shimmy shake usually does it.

It's a bit fiddly...

...you'll get more wiggle room if you remove the fan cowling (four philips screws) which will allow you to angle the rear of the exhaust up and down (to help get that flange off).

Also, the threads on the studs can stop the flange from sliding down (the studs can get splayed outwards after tightening), so it's a gentle fiddling act.
