    Hillsy bought another Divi

    Hey guys - I've been mucking around doing non-motorcycle related crap but time has come to get another XJ900s.

    This one was too cheap not to buy - I got this one for the same $$$ I sold my old FJ1200 for and it's easily twice the bike.

    This one is a 2000 model which has been pretty well looked after.


    I had a 97 model about 15 years ago and whilst I knew it was a great bike, I still had a bit of crotch rocket left in me at that time. Fast forward to now and its ticking a lot of boxes again....














    Pretty low K's for one of these....





    Rides sweet....

    So the bike is pretty solid but the front brakes left a bit to be desired.

    The Internet told me the R1/6/FJR blue spot calipers are a bolt on fit to the Divi front. The 01/02 R1's had gold spot calipers (essentially the same) - which are the ones I found locally.


    This is the reason why the caliper swap made sense - upon closer inspection pitted pistons would mean about $150 plus in refurbishment v $100 for two complete R1 calipers:





    So, the magic of eBay made these suckers turn up at my door within a few days:





    Pads and all:



    And ceramic pistons - so no more pitting:



    No wear on the pad pin so probably off a low mileage bike:



    Now another advantage here is the R1 caliper is about 340g lighter than the Divi ones.


    R1:



    Divi:



    So, let's see if they bolt on....



    Oh yes they do - pad area lines up beautifully as well.


    So a quick bleed and here they are:



    And fuck me they are magic! Heaps better stopping power .... lighter lever action.... just ACE!

    Four piston callipers instead of two piston callipers, yes I should think you made a Major upgrade there.
    ... but you are going to find that monoblok design just a little harder to service in the long run.

    Nope - I already slid the pistons out and they are ceramic coated - slide like butter. You can pop them out without having to unscrew the gold spots. Can remove the pads without taking the calipers off as well. Seals are cheaper, pads are cheaper....it's just got win written all over it.

    I have one set that is the same design so I'm going to find out sooner or later
    One of the guys I ride with tried servicing his last season and reported that he messed up the seals,
    apparently had a heck of a time finding individual component parts and ended up replacing the entire calliper ymmv.

    Four pots are an incredible performance improvement over two on the same side highly recommended upgrade.
    You will not only have better braking performance but will also find feedback through the lever is greatly improved.

    Nice clean find!

    Hey, stay safe there. The fires are all over the news here in the states.

    OK so I thought I would play around with the ignition timing. Most bikes are timed quite conservatively with the idea being they will be able to run OK on any crap fuel that is available wherever you are on the planet. The reality is most fuels (over here at least) are pretty good and you can advance the timing to make the bike actually run better.


    So, I could have bought one of these suckers off eBay for about $50:





    But where's the fun it that? Also, I cant adjust it - it's fixed at 4 deg.


    So, I opened up the cover here:





    And discovered the backing plate is screwed in place with 2 screws (the black ones):





    Which means I could slot the holes and rotate the plate which will adjust the timing.






    So, first thing to do is to find a suitable spot to mark the current (stock) position timing:





    This way if everything goes pear shaped you know where you started from...






    Then take the pick-up off and remove the backing plate (that green shit is Mr Yamaha's thread locker)





    Now scribe some degree marks on the plate in the direction you want to go (OK - it's not that tidy....):





    Now drill two holes beside the existing mounting holes:





    And file them out to create 2 slots:





    So here it is back in the stock position:





    And here it is advanced about 4 degrees:





    Button it all up and we're done. Probably took about 30 minutes all up - and the benefits were immediately obvious. Started first hit, pulls much smoother through the low and mids and generally runs sweeter.


    And it cost nothing to do but a bit of time tinkering - which is good for the soul....
