I'm installing the corse system on my 1078. It's all going fine but I can't figure out the fasteners at the cat and frame.

I only have a 910 manual and they are standard bolts on that bike according to the manual,
but the 1078 is different, the fastener just spin in a rubber grommet
Anyone know how to remove them?

yeah, that much I can see...

Sorry I didn't figure this out before I posted.

There is a two part fastener that spins in a rubber grommet, the outer fastener stays in the frame boss and the inner fastener screws into it with a pin that protrudes into the bracket on the cat.

You have to hold the outer piece with a 19mm open-end and loosen the inner pin with an allen.

Weird set-up that had me scratchen my head.

carry-on :smoking:

Hmmm, did you put the O2 sensor back in? I was going to leave it out, there is a plug where it goes.

Is the new ECU closed loop or open loop?

On further examination it doesn't look like you installed the ECU that came in the kit. It should eliminate the O2 sensor - Right?
If it's like the corse kit fitted to my 1090 the race ECU doesn't need the 02 sensor, should be plugged.

Yes I have put into the O2 sensor.

But I do not use the ECU that came with the unit. Since it belongs to a 1078 and will not work properly on my 910.
The purpose of the new ECU is that you disconnect the O2 sensor. Then you will pollute a little more, and have even more fun when you're driving.

I finished the exhaust system yesterday - it was quite the project but now that it's done I'm glad I did it myself instead of taking it to a dealer.

The second picture is the fastener that started this thread - never seen anything quite like it - it is held in the grommet with a snap ring.

Third pic is the location of the ECU (red connectors) - I was able to change it without too much trouble without removing the airbox or throttle bodies.

I decided to give the pipes a quick polish just to give them a more finished look.
I didn't polish them to look like chrome, just to clean them up. After a five minute ride they already started to turn gold.

I left the O2 sensor out - I'm really glad because it was a bear to remove from the bike.

The new system is a nice puzzle - fun to do really and the fit, when done, is really nice.

I was able to lightly polish over the laser-etched Corse logo without removing or damaging it.

The finished bike looks good. It's not too loud and it retained that sweet intake roar that I love about the Brutale.

It's been snowing out today (that's why I'm here writing this instead of riding) so I haven't had a chance to ride the bike but around the block.

I'll get a better impression of how the exhaust system works later in the week.

Nice work and nice pictures mate, but did you replace those plastic fuel fittings with metal one's while you were at it. ??
No, I thought about it but I didn't have any on-hand and I wanted to focus on the exhaust and ECU.

It's not too hard to remove the tank if you have a helper. I can do it another time.
I do need to get a set so that I have them on-hand if the stockers give-up on me.

Flynn, that looks just great! Let us know how it rides!
I got it out for a ride today - over a hundred miles.

The sound is not too loud, the raspy Ferrari sound is still there just a bit more pronounced.

Gone is the roller-coaster surge ride in and out of town, the bottom is smooth and comfortable now.

The bike also grew a pair of big hairy balls! :jsm:

Seriously, it's like a different bike - I'm amazed at the difference - not only does it have more power everywhere but its smoother, easier to ride, and more refined.

I can't get over the transformation.

I needed to sell one of my bikes and this was very high on the list of candidates to let go. Now I'm glad I didn't. I think I'll get along with it much better now.

The pipes are already turning gold - I like it.

(PS; I also checked the millage and I got 31 MPG on this tank)
