    Managed to escape the office a little early this arvo, so had a little bike time.
    With the new tyres, the original paint was starting to chip a bit, so I got my Tamiya model paints out (enamel which I'm also using to touch up the fairings) and gave the chips a coat.




    Will probably take 2-3 coats.


    My chain tool arrived so I could now tick that off, all the cogs are cleaned and derusted as best I can.


    Comparing the last chain to the new one, I had one extra link on the new one, not sure why, but so be it.




    So I dremeled the pins off, and it's now one link shorter.


    She fits




    Lock and load.


    Using this chain with the lock pin is pretty easy, no worries with riveting pins.




    I also painted the chain cover, ensuring to keep the tyre info intact to make sure rego people are happy.




    I was finally working on the left side, so I had a few bolts to take off and de-rust. Good as new.


    Tomorrow we work on the front brakes.
    Carbs maybe next week,
    then finish the fairings, and put it all back together.

    And it continues. The plan was to have the front brakes on today.
    I started by taking apart the calipers apart and pulling the pistons out.






    The bike lived in a coastal suburb in Sydney, there was a fair bit of surface rust around.
    Once I got the pistons out and cleared the rust of, they were pretty well pitted.




    I reckon these are dead. Thoughts? it's $128 for 4 new ones.




    Cleaned up the rest of the bits and will leave them to soak a bit more.




    The handle bars were a bit worse for wear too. I wasn't sure what to do with them, I gave them a coat in matte silver, and didn't really like it.




    Stripped them well and I like the raw metal look, if it doesn't last long I'll get them powder coated black I think.




    Both foot sets are now done, the left had the shifter adjusted and feels all good for now.


    With the brakes needing parts I thought I'd play with the fairings a bit.




    There are a few cracks here and there, so nothing like a big of Q-bond to make them rock solid.


    I have white and red touch up enamels, which should be ok, but finding that metallic/pearl purple/blue is proving challenging.
    Anyone have a good touch-up paint mixer guy?




    They come up ok with a bit of a polish, but there are quite a few chips which need paint.






    the fun continues.

    Brake day. This was always going to be a bit time consuming, but that's fine, brakes only slow you down.


    The new pistons arrived and it was time to assemble the calipers.




    The key part is right where the seals are, so there was no saving the old ones.


    Firstly had to rip out the old seals, and as the diameter of the pistons is pretty small, this was quite tedious.




    4 seals each side.


    I was planning on painting the calipers myself, so a preparation is key.




    nothing beats a good wire wheeling.




    This is the stuff.


    I taped up all the screw holes, the bleed, the fluid feel, but thought the piston chambers would be a big hassle to tape up properly, then I realised I wasnt going to be using the old pistons again, so they made the perfect mask.








    3 coats with at least 10 min between and they are looking good.


    Then I gave them a good 3 hours plus to dry properly before taking them down.


    and then bake for an hour at 100 degrees C.




    and ding..




    look almost as good as powdercoated.




    ready for assembly with new hardware



    the new seals were a bit fiddly to pop on correctly, they kept twisting on me, but finally got there.




    pistons in and brackets on




    Don't forget the spring




    I went for organic pads, some say they feel better, I'm not planning on tracking this bike just yet.




    all new hardware in ready to mount.


    tomorrow we mount, and then rebuild the master cylinder.

    Put the brakes on.
    It's quick and easy when there is no fluid.





    But, that sound that I always dread:





    Something was grinding. Wasn't sure what, the pads were well off, there didn't seem to be any part of the bracket or caliper itself hitting the disc.
    I thought the disc was a bit warped, spinning it, the disc looked rock solid straight, so I thought maybe it's a little egg shaped as it was only really grinding on a certain spot.
    I thought of grinding the disc down a bit, which wouldn't really affect it's performance. But I took the calipers off and had a good look.
    Nothing seemed out of the ordinary.
    It did look like it was grinding on that spring spreader thing shim, which was a little weird.
    Looked that part up online, and realised it's meant to go half out.



    Like that.
    That'll do it.



    Now silent. The sound is rain pouring on my garage this arvo.


    The other thing was to fit the triple top clamp.
    I was thinking of DIYing this again and using the caliper paint, but I figure this part tends to get pretty hammered , and you are always looking at it, so powder was the way to go.



    wired



    Boom.
    Joe at Forza Performance Coatings did a stellar job. Just the way I liked it, not too matte, not too glossy.





    Putting this back on was fun, it's like the icing on the cake.

    Carb kit arrived.


    Question is, do I just strip them out and spray the crap out, but leave all 4 linked, and fit the new parts:





    Or take them all apart and soak in a bath to make them all super clean:





    My concern is putting them back together will be much harder to balance.

    She's ALIVE!


    Running sweet.
    Phew.


    Took my time doing the carbs, doing one at a time to ensure parts aren't mixed up or forgotten.



    Good idea to take a pic as a reference image, cus it's very easy to stuff up the other of things.



    Each carb was emptied, the old jets and valves filed under B for bin (well no, I'm going to keep them as a do not use spare)
    Wurth carb cleaner seemed like the best stuff, and a good spray inside and out did it.



    this tiny pin holds the entire tune. I like this carb business.


    shiny gold, new parts are in and adjusted to factory specs, 1 and 3/4 turns open.


    Popped the carbs back on, hooked up my dodge fuel system, and....





    Started pretty easily!
    Running fine. had a litlte bit of smoke, reved it out a touch, let it warm up, and she was cleeeean.



    Before the carbs went back on for good, I had to clean up the thermostat housing.
    When I first had it running badly a few weeks ago, water was pissing out of this, and looking at it, it's not difficult to see why.


    My favourite wire wheel, a new OE seal:

    and we are leak free.


    Playing around I also snapped the connector on the Thermo switch for the radiator fan, so popped the new one one

    and filled it up with fresh coolant.


    Popped the tank back on and gave it another test.
    Hmm, ran for a second, then died, hmm must be a fuel thing. Let me check the petcock tap. Nah all good. Try it on reserve, same same, half kicks, wont run. Hmm, could it be busted?
    Took a look around, saw the vacuum hose to the petcock popped off from the engine side. That'll do it.




    Success.


    More work tomorrow.
