The bleeder at the MC is almost always under pressure, so simply cracking it you should here a "PFFFT". Once you do, its bled. The ABS is not involved in the bleeding. You won't be bleeding the ABS pump, just the lines and caliper. But you shouldn't need to bleed anything just form it sitting unless you rode on low fluid.

It could also be the pad is worn  ;)

There are only 1,300 miles on the bike, so that is unlikely haha

the reservoir looks like it is filled to the brim (above max) im not saying that as a good thing, just something I just noticed. It always felt fine except one day after sitting for 3 weeks or so there was just practically no feel in the lever when I squeezed it at start up...

Do you have a pic of the threads? 200 bux would have gone a long ways toward a solution, when I had the shop..
If this is targeted at me, its a plastic reservoir and cap. My lathe and mill can't fix that, doubt yours could either.

Yes, it was for you..
If I can see the parts, I cant say that..  Let me say though sometimes there is a clever solution.
I made a nice billet reservoir for one guy on here..wish i had a pic or the details..

My mom's '01 Subaru Outback had shredded its serpentine belt Thursday. We bought another belt and I installed it where it had broken down in the dark by flashlight.  The tensioner felt OK. Only problem was within 3 miles it ate the new bet and the tensioner had lunched the bearings and the bolt securing the bearings and tensioner wheel was missing. Had the car towed to a shop near where Mom lives.  Found out today they weren't able to fix it and ordered a replacement tensioner out of Knoxville, 100 miles away, and it would be here Monday.  They quoted her $200 for the work, $75 for labor, $30 for the belt we paid $25 for a Dayco, and looks like $100 for the tensioner. The Advanced Auto in Bristol quoted it for $76 and they could have it in 20 minutes, about as long as it would take to drive there to buy it.
So, they made some markup.  She's not a happy camper and requires hand controls in the car due to an accident about 15 years ago.

So, given the usual Brembo runs $200 at least and more like $250 your $450 is a little high...wonder what the dealer pays for the part shipped to their store?  Wonder what they would charge to install it?

Crazy thing is they are charging $75 for the work and I have the beauty cover off so it is one bracket and then remove a 10 mm nut and loosen a 12mm nut to remove a guard and then a 8mm hex to remove the tensioner.  20 minutes work tops.

I'm presuming $75 is an hours labor.

Time to get this monoshock mounting business wrapped up...

I decided to make a mock up of the monoshock with an adjustable section so I can set my desired ride height.  Here was the workflow:

Make the ends based on what I am having Racetech make for my spring ends:


Didnt spend much time making it pretty, but it should work!



If anyone needs this when I am done, you are free to use it as well!

Bryan,
That is brilliant.  When I get to the 550, I'm still thinking I want to do a mono-shock on it with that CBR600 rear end I'm going to be using on it.

Keep that around because I just might want to borrow it.  Very cool.

I officially approve of how the new subframe looks, so I sealed it up with a couple welds  ;D



I also mounted and welded in (top and bottom) the plate where I will mount the top monoshock mounting plates:

"There are some things nobody needs in this world, and a bright-red, hunch-back, warp-speed 900cc cafe racer is one of them — but I want one anyway, and on some days I actually believe I need one.... Being shot out of a cannon will always be better than being squeezed out of a tube. That is why God made fast motorcycles, Bubba." Hunter S. Thompson, Song of the Sausage Creature, Cycle World, March 1995.  (http://www.latexnet.org/~csmith/sausage.html and https://magazine.cycleworld.com/article/1995/3/1/song-of-the-sausage-creature)
