    Shit.
    Could've sworn you meant swivel.

    The swivel is exactly the same length as the banjo bolt w/ copper washer (as the pic show)
    My bad forgot to include the banjo and the second washer in the equation :fpalm
    The swivel is much longer than the bolt, but still doesn't bottom out inside the master.

    Yeah, sort of. Since the face isn't the same as the banjo bolt it doesn't really matter.

    That's what my mechanic buddy Yngve suggested as well. I've sent them (HEL) a msg asking for an adapter to start with.

    The rear pipe might have the correct face so the new rear hose with the same swivel connection will fit. Anyone know what the end of the pipe looks like?

    The planned trip this weekend has been cancelled due to Yngve's bike stuck in 4th gear mid day yesterday (R80GS), so my bike is going into winter storage next week and the hoses will hopefully be sorted before spring :D

    The red hose was the first one I ordered and that had the M10x1,25 swivel (wrong thread pitch).
    The new hoses have M10x1,0 (graphite colour)
    The red transparent hose is a different shade of red compared to the bars, which look pink when you route the hose where it's supposed to go, therefore red is not an option now. The hose is sexy though.

    Yeah, but he paint is not really bubbling either. It's like the bubbles are solid, not hollow, like it just expanded. Getting the paint to separate or come off is very difficult, even with a screwdriver (like a scab I had to try to pick at it). Guess that's a good thing.

    I thought the consensus was that we bought Ducati Brembo rear masters since the same complete new Brembo master is cheaper from Ducati than a repair kit is from BMW?
    My link to the Ducati masters is now dead, but there are lots on eBay.
    YOU HAVE TO CHECK THE CORRECT PART NO.

    Wayne has some info on it, of course: http://www.f650gs.crossroadz.com.au/BrakesAndABS.html

    I haven't checked but maybe this master one from the F800GS fits?

    Well i did the seal change, left the shaft that was there, since i don’t have a new spare. Changed the coolant, some fancy japan stuff the guy at the bike shop had. Did a 96km test ride tonight, seems fine.
    Something somewhere came loose at some point and the auxiliary power line (extra lights, phone charger, cigarette lighter, etc) stopped working, then i started up again. Checked what could be reached without taking the bike apart, couldn’t find it.

    This is a monument for Chinggis Khan, supposedly the biggest horse in the world.

    Thanks for all those links GS - I can find them all day long from Europe, but I was hoping to find one stateside. I ordered one that I thought would work, but it seems I ordered the wrong one.
    I'll order the duc equivalent - once I determine the right part number. There seem to be several options here in the us.
    When I find the correct kit, I'll post up that part number here.

    Thanks again!

    Yeah well, this has been an exercise in frustration trying to find a kit here in the US. There must be a thousand different models of bikes using the same 11mm mc out there, but I'll be damned if I can pin down one of them.
    When I talk to a KTM or Ducati dealer, they need a specific part # or model/year to search for. And so far, I can't find that info online.
    Shouldn't be this hard! By the time I figure all this out, I could've just ordered it from Italy and been done with it, but winter is coming! and I want to squeeze in a few more rides!
    Arghh !

    The only bright side of this story, is that when the mc failed, I was only a couple miles from home, and not on top of Prairie Mtn, which is where I was headed. Would not have been fun riding down without a rear brake. Good bike karma!

    I'm holding a Brembo 11mm cylinder rebuild kit in my hand right now. The part number on it is:1100436241.
    I got mine from Gowanloch. Great service.
    Pretty sure they say Ducati Monster 600 has that rear mc? Yep...
    Suits all pre 2007 Ducati Monsters with dual sided swingarm 600, 620ie, 695, 750, 750ie, 900, 900ie, 1000ie

    You can get the right side panel on/off with Heed bars fitted (Air filter access) but it's really tight and I did put a mark on the panel, not that I mind considering I just spent weeks repairing it from being in three pieces and it's not like it's 'new' anyway (Check the break/crack running through the "DAKAR").

    JB Weld Plastic Bonder 50133 epoxy works well on the polypropylene, reinforced with galvanized steel staples. I did sand it roughly with 80Grit Dremel wheel to give the epoxy some fine grooves to grip into. It's sets to a very "Tough/Chewy" density, not brittle at all. It has some 'give' and will flex a lot. I tested it by applying some to a bit of greased paper, then peeling it off once set. Couldn't break or crack it, just bent and wouldn't snap. I twisted it until it went 'white' from stress and it still wouldn't come apart. Tough stuff! AND it sticks to PP too!

    I've stripped the self tapper threads in my air filter / battery tray for the umpteenth time. Before I've managed to use bigger self tappers and grind the heads down to fit in the clamp part. But I'm out of room/luck this time.

    Has anyone modified their Battery Tray / Air Filter clamp to use metal thread bolts (say M4 / M5 thread?) instead of the self tapping screws into the plastic?

    I'm thinking about using "Furniture nuts", heated up and screwed into the plastic (drill suitable hole first) while hot, melting the plastic around it to hold it in 'better'.

    The other option was using the JB Weld mentioned above to 'Glue' in a 'uncrimped' RivNut, or even a Rivnut crimped onto a washer for larger surface retaining area. Drill small holes in the washer ("perforated") so glue can go all the way through front to back. Cut some grooves into the plastic for the glue to go into, creating a mechanical retaining system once the glue set.

    Anyway, if anyone has done it, what did you do? And more importantly, did it work? :-)

    Have been expecting to have to look at it but have not as yet, I would go the furniture nuts and use heat to insert, the hex fitting would make it easy

    FYI for the Oz riders, met up with Norman and Maggie Magowan of Adventures In Yellow for coffee today, they have survived FNQ and made it onto the east coast NSW, they left Sydney heading to Melbourne via the coast today. If you see the 2 yellow 650GS's buy them a beer or cold beverage, you could not wish to meet a nicer couple, they had a big thanks to Damian for organising the fuel pump assembly up to Darwin for them, it is performing well

    Well just a quick note. I finally had to give up and just get a new radiator for my 2001 F650GS Dakar, first year. Tried the fix but is still leaked. So after 569$ its all in place. I had changed out my oil. Cleaned all filters. Put on new sprockets and chain. I have a Renazco seat which totally changed the bike along with ROX risers and a tall C Bailey shield. Also have added a more powerful lithium ion battery. I was doing this as I was going to sell it and get an African Twin to complement my Stelvio. But then I took it out on a remaiden voyage and realized how smooth and clean this Dakar is now. Like most European bikes they take a lot of massaging but once there they are real nice. It has only taken me 17 years and 10,000 miles to have a bike that is equal to the Honda engineering out of the box.

    Today it is a bit hard to realize how revolutionary this bike is. With all the above done, and many miles on my 650 lb. Stelvio it feels like a Honda CRF250 in size. I think I will keep it.
    You absolutely couldn't find a machine near this good for 5,000$ which is what I would sell it for. Kelly Blue Book is so worthless for the well cared for machine. If I get a chance I will drop a picture though you can see it in my page. All that and it gets a solid 60 -70 mpg and can run 80 all day long one or two up.
