    I fitted a Magura one to a WR250 Yamaha, and I don't think there was that much difference to the cable for the cost. I prefer to extend the arm or use a lever with different pivot centre to get the same effect.

    Finished the R6 rear shock conversion and fitted the freshened up ass end on my fzr250. Also put all the fairings back on after a tidy up.

    @Andych Do you like the way they feel? My experience has been that cables give much better feedback. Durbahn in Germany was doing cable conversions for hydraulic clutches. Don't know if he still does because his website is such a maze.

    I haven’t used one so far Blair. I think I am going to need to put a 350 clutch into the SRX and it needs a new cable. This system is about the same as a new after-market clutch cable. So I might give it a go just to see how it works.

    Tinkering today mostly as I needed paint and Bunnings etc were closed.

    I decided to cut the end of my SS engine pipe so I can sort out the correct size piece to go on.
    Pulled out the trusty Ryobi cordless grinder and thankfully grabbed my safety shield / helmet.
    This was an old cutting disc but still quite usable.
    When it let go the piece that broke off hit the shield.
    After a few expletives and a new disc I finished the cut

    Always remember children, wear your safety gear, doesn’t matter if is just a quick cut etc.

    I should add that the face shield is perfectly fine... I did buy a good quality Polycarbonate one though... I dont go cheap on Safety Gear.

    I try to keep the direction of rotation away from vital body parts. Safety gear or not, it is an extra measure to keep safe.

    Does anyone know if you can but new SS pistons for FZR250 3LN calipers?
    They have been butchered previously and won’t budge with compressed air.
    Part of the seal on the small piston was protruding as well.
    Looks like it might be a grease gun effort to move the pistons.

    This one was separated to fit in the Ultrasonic Cleaner.

    Wow, those are absolutely butchered.

    Usually, corrosion sets in behind the dust seals... also, most brake clean products will swell rubber seals... brakes should be cleaned with warm soapy water and an old toothbrush as you probably know, sometimes the people working on your bikes at a shop are not the brightest (and I've had my moments)

    Suggestions... heat gun, flip over, and wham the thing against a block of wood until they fall out.

    A good machine shop should be able to make them for you, but they may be more expensive than new.

    Hmmm I will need to get tham out and measure them.. The Titan Classic items are much cheaper than getting SS ones from the UK.. that kit for both brakes is A$336 but I already have seal kits for them.. It will depend on what condition they are in when I eventually get the pistons out.

    The outer edge's where your's are damaged is usually just where the outer dust seal run's
    When you get the piston's out you should be able to see where the fluid seal sit's deeper inside the caliper

    Wonder how much it'd cost to have the piston's lightly machined and re-hardchromed ?

    The guy from Titan is quite responsive to making them if the part is shared across multiple models. Might be worth sending an email when you get them out. I was going to make some for my Honda but have had trouble getting them TiN coated.

    Probably not worth having these ones machined and hard chromed.. If the sizing is right the Titan ones would be good... I even looked at Calipers on AliExpress but they all seem to be 40mm mounting spacing.. and I couldnt find adapters to go from 82mm spacing to 40mm.. .

    Managed to get 1 caliper fully stripped. It took the butane torch to almost burn the seals out to get the pistons out and they are really mangled.
    However, they may well be salvageable.
    After a good 30 minutes in the Ultrasonic at 60 Celsius with a nice mix of Simple Green (Orange) concentrate, Vinegar and water the bores look ok.
    There is a machined groove in the bottom where the brake fluid comes in. I don’t think the pistons are meant to go all the way down and that will keep any damage above the main seal.
    If they do leak I will have to find another good set of calipers I think as the piston kits for these are just too expensive.
    OEM kit or the titanium work kit well over $300 for both sides.
    If you ever were knocked back on register and told to do a full brake overhaul on an FZR250 you wouldn’t be getting any change out of $700 odd with new discs.
    Crazy prices.

    This was the other half after removing the pistons. About to go into the Ultrasonic cleaner.

    This is how it came out

    You can see the lower recess in this pic and the one after has some old sealing ring in the bottom to show where the piston should sit.

    I finished the forks then took the KDX engine out of the other bike and returned it to the original bike. After all that progress, I decided to drag out a different project: zxr250. Started cleaning the carbies, until this:

    There was a leak in the can, probably fell and damaged the valve, or rust - that's coastal living for you.

    Took the t500 for a spin , needed fuel so I stopped and filled her up, after 5 mins of riding , I had to stop at some lights my fuel cap fell off , spewing

    Ride home with one hand holding it on, I need to find a replacement pin

    Every time I brake, fuel would surge out. My poor old flabby became a fuel rag
