Question Removing the 919 midpipe?

I want to get some work done on my exhaust but need to remove the midpipe. How do I do that?
Can it be removed without taking off the swingarm?
How about if I remove the rear shock to get it off?

Thanks for any help.

Removing the rear shock should allow just enough room to get the midpipe out, but you might want something to hoist the rear of the bike up. The shock should pivot up enough to get the y-pipe free. Upon reassembly, centering the shock so that the lower bolt can be fitted may be difficult. If you can hoist the back of the motorcycle by the rear tail section it makes the job much easier.

There may be easier methods, but this is what I experienced when I switched to the Hindle 4-1 exhaust.

It's a pain, but it'll come out.

I went through this a couple of months back and I dont care what anyone says, I had to REMOVE my shock to get it out!!! I tried all kinds of ways to work it out with no easy way! Read my plight at this thread, lots of good thoughts on this also!

OK, thanks guys.
Removing the shock doesn't sound so bad. I was hoping I wouldn't have to remove the swingarm.
I don't have any way to suspend the rear, will putting it on the centerstand work?

It should work, but like I said, re-installing the lower shock bolt can be difficult. Having someone help lift the tail section while I aligned the shock made it possible for me.

I installed mine by taking the lower shock bolt out and jacking the bike up by the engine. If you don't have a way to use a bike jack (I made an adaptor out of 2x4) it's going to be difficult.

I've covered this before. I used an articulated ladder for an "A" frame. Placed it over the rear of the bike. I don't have exposed rafters in my garage so the A frame was a necessity. I attached a dirt bike tie down (ratchet type) to each side of the A frame and to the rear portion of the bike frame (seat off, do not use the grab rail). I lifted the tail till the shock was unweighted. I unbolted the lower shock bolt and swung the shock up. Then I ratcheted (is that a word?) the tail up a little more, rear wheel still on the ground, till the Y-pipe could just be twisted out of it's little hole! Then lower the tail by the tie-downs back to where the shock bolt will go through, tighten, and lower back to the ground. Once you get the tail up in the air, it's pretty easy to see what has to be done in getting the Y out. Hope this helps.

Put it on the center stand.
Remove the rear tire.
pull the shock bolt.
The swing arm will drop out of the way
Remove the "Y" pipe.
Simple.

When I install a new chain, I rivet the master link on, while it's still off the bike. At the work bench with the help of a vise.
Then I pull the swing arm to put it on.
It's a lot easier than messing with it on the bike.
To pull the swing arm:
Pull tire.
Pull hugger.
Remove lower shock bolt.
Pull the swing arm pivot bolt.
Remove swing arm.
Done.
Pull drive sprocket cover.
Sling chain around sprocket.
Put it all back on after cleaning.

Oh... I use the PHOBMAN stand. That thing rocks!
It's basically the same as your center stand as far as function goes.
