'94 900 Supersport: Cleaning, Small Repairs Etc.

Discussion in 'Builds & Projects' started by doublehead, Oct 15, 2018.

  1. That would be great, thanks!

    That seems to be the right one! The stuff I ordered was used by the previous owner (or his workshop) so I looked up the most similar looking parts. The anti-rattle stuff fits the brake fine, but the retaining pin is too small in diametre.

    The brake is almost the same as on my Aprilia which also has the circlip.

    As I'm planning to register the bike in April, there is still some time left to make sure everything is properly set up. :blush:
     
  2. Someone I know had some Brembo brake spare-parts and he had a set of the parts I needed:
    New parts on top, "old" parts below.

    As it was sunny outside I took a few pictures outside.

    Needs new Agip-stickers. :)
     
  3. Top ones are correct. The circlip is a pig to fit when the caliper is bolted on. I added a small R-clip by drilling a 1mm dia hole close-ish to the circlip.
     
  4. Yes. Yes, it is. :laughing:
    My RSV has the same circlip, it never fell of, even after changing the pads a few times, so I'll leave it as it is now.

    The pins on both sets have the same diametre, 4.8mm, so besides the groove they are identical.
     
  5. Looking at those pictures, the top set of parts are what I have fitted on the front calipers plus the addition of the hole for the R-clip. The lower set are what is fitted to the rear caliper, the retaining pin is in rock solid and I normally use a pin punch to knock it out. The pin is kept in place by the pressure of the anti-rattle spring, which tends to suggest that the spring is not applying enough upward pressure if you are getting movement on the retaining pin.
    Pictures to follow shortly
     
  6. In the pictures of the brake pins and springy things; the correct parts for the rear brake (Ducati Part Number 612.4.013.1A) are those in the clear plastic 'tray'.
     
  7. I Agree with AL.
    I've had 3 (still got 2) 900s and they all have the arrangement as per the top items in the photo above.
    I have never seen any items similar to those in the bottom of the photo.
     
    • Thanks Thanks x 1
  8. Perhaps you have a different caliper??

    Idiosyncrasy of Steine-dinse website - always use the parts diagrams for the 900SL - there you will see which are the correct items (like wot I have already mentioned).

    I cannot find any reference to that part number being superceded.

    But as I have said previously; maybe your parts are just an alternative for the same caliper (as fitted maybe to Aprilias) and if they work, then probably OK.

    The brake pads all seem to have a small dip / recess either side of the tags for your version of the springy thing, regardless of pad manufacturer.

    AL
     
  9. Hey this is Ducati we're talking about, given the age of the SS and how this relates to Ducati history and the parts they had to hand, I'm not surprised that something as small as an anti-rattle clip can be so different.

    As you say AL it works, and at some point someone has drilled a hole to put a split pin through the pin probably because they were worried about the pin coming out.
     
  10. Thanks a lot!
    Perhaps those parts have been replaced with the sheet-metal as it's an easier manufacturing process and therefor cheaper - the functionality is the same. Both setups seem to work in my caliber, the sheet metal has the same points of contact as those cone-ish pins. The pin doesn't really sit rock-solid, it wobbles a tiny bit, but with the circlip it should be good.
     
  11. Done a few more minor things and - after I install a final seal tomorrow - it'll be ready to go:
    20190320_152618_HDR.jpg
    Agip stickers where put where the original ones probably were.
    20190320_152635_HDR.jpg
    Rubber tubes.
    20190320_152651_HDR.jpg
    After refilling and bleeding the brake I noticed there is fluid leaking out of the seal when there is pressure to the pedal so a new one was ordered.

    Routing the brake lines etc. took a while but worked out well. the Triumph accelerator cable seems to fit in nicely.
    20190320_152730_HDR.jpg
    So clean. Won't last long.

    Cable ties for the idle screw. I'll fabricate a proper solution in the next holidays. Probably.

    The 90s tank pad got re-installed with fresh sticky stuff.

  12. Great work, love all these details. Now you deserve to some Springtime riding. Enjoy!
     
  13. I made a remote idle screw adjuster from a spare trip meter knob and cable, plus a spare idle screw.

    You can see my knob below.

  14. Great idea and I see I’m not the only one to polish my frame.
     
  15. Great idea. And that's one shiney knob. :laughing:

  16. First ride, roughly 5 miles, drove half of them. :motorcycleduc:
    Bike started stuttering, engine went out and wouldn't start back up.
    After walking the thing back home I took a closer look: One of the jets in the carburator which is activated via the pump didn't let any fuel out (sitting on the bike it's the left one). Took the carb apart, again, cleaned the jet and put it back together. Cleaned the spark plugs as well - they where wet and black.

    More stuff checked:
    - Both Spark plugs have bright sparks
    - Fuel system works, took the hose off the carb and turned ingnition on ->
    Plenty of fuel comming out, seems to work properly, don't have a pressure
    tester
    - Cambelt didn't jump or anything

    After it was back together it almost started. There seems unburned fuel in the engine (judging from the BANG!!!!11 while trying to start from the right exhaust) that will hopefully vent out until tomorrow. I removed the Spark plugs so this might work better.
     
  17. So it was the fuel filter between within the tube between tank and carburetor. Changed it and now she runs pretty shmooth:

    Clutch is sqeaky when taking off, besides that I really have to say
    it's the most comfy touring bike ever.
    Srsly, it's much more comfy than my RSV and quite a bit less noisy. I like it. A lot.

  18. The clutch on my M1000Sie does that occasionally, I think it may just be a bit of friction material dust that hasn't found its way out of the little vent hole at the bottom of the cover! Doesn't cause any problems and the clutch is quieter with the solid cover. I hated the extra noise when I had an open carbon cover on it, so I put the OEM one back on.
     
  19. That's good to hear. I'm totally new to this engine and still have to get used to it and the noises it makes.
    Would cleaning the clutch with brake cleaner help? Or is that a totally bad idea?
