    Apparently the go is to get one off an R6 as lot's of people upgrade those, and we can use the original R6 one with some slight mods... might do this myself at some point. Anyway, if you get a reasonable blue slip place, they shouldn't pick on your shocks unless they're really stuffed.... hopefully you can get some word of mouth where a sensible bike blue slip place is....

    'Un-servicable' shocks are made 'servicable' by cutting the top of the shock off and welding a machined collar into the tube that has an internal thread. This had a threaded plug screwed into it to make it 'servicable'.

    Yeh I've got another place up my sleeve, should have gone to them to begin with but lesson learned.

    Thanks Murdo, didn't know that. I think I'll get the other shop to take a pre-emptive look at it and I'll innocently ask for an opinion...

    I was playing with the idle screw today and I think I went backwards. After a 20 minute run I noticed a few things:

    1. The bike doesn't like taking off quickly after riding slowly (and cuts out when it has been sitting still and you try to take off).
    2. The idle seems... a bit too inconsistent. It doesn't seem to settle, but it's not going up and down massively in the rev range.
    3. The temp guage was at about 2/3 (on the hot side) after the run. Given it's a warm day, I've never really seen one go above half before so that made me a little nervous. Coolant is new (Nulon) and I'm pretty certain everything works... maybe the CR8E's make it run a little hotter, I don't know.

    My gut feel is that it's still flooding in the low rev range. It can get a bit boggy under 4k but throught the higher revs it seems to go fine. I got it home and it cut out, and I couldn't get it started again. It wanted to start but it wouldn't kick off. Hmm....

    Yeh... I'm toying with leaving the pilot screws and putting all the needles up a notch instead. A good 20-30 minute run should test whether that's an improvement or not. My gut feel is the richness is what is causing it to cut out, because when it starts and gets through the bog it goes very, very well.

    The only problem is that I did the bottom end on my car today, so I may have to put this project on hold for longer than I had hoped... :headbang:

    Any recommendations on rear brake pads guys? I've heard to steer clear of cork but I've never actually done pads before.

    I used metal gear pads on my Ninja 250R, no complaints, suitable stopping power for the rear and quite capable of locking the rear

    Thanks grey I had read all that, it seems kevlar may be suited for "everyday" riding and that's normally the type of use I would start with so I'll go with that. Metalgear ones look pretty good too.

    Ok so leaned her up today, 2nd notch from top and wish I'd done it sooner. Runs like a dream. A bit of fine tuning to go, but no more flooding (yes, there is another fizzer out there that doesn't flood!) which is the main thing!!

    Next on the list fork seals, rear shock, rear brake disc and pads and if someone doesn't pass this bloody bike I'm going to go Pyro on their ass!!

    So after ringing a few places to get prices for fork seals I was a bit gobsmacked that some were $250 while others were $400!!

    Reading up on the subject I decided to give it a go, but I have a slight problem. Can't seem to find a way to prop up the front of the bike. I can't hang from the pergola as the crappy wood is not liking the load (have to rebuild that too at some stage). Any tips on securing the bike to get the front wheel/forks off? I was thinking about putting a bar of some sort between the exhaust and the engine but the angle of the engine doesn't help much, and the exup cables get in the way. Hmm...

    Take fairings off use piece of wood under frame on flat spot and use car jack mate or make or buy a front wheel stand image.jpg

    "some were $250 while others were $400!"
    WHAT? For real?
    I am going to produce fork seals if this is true.

    Where would you put the wood exactly? I thought about spanning something between two car wheel stands and putting the bike onto it but I can't see anywhere on the bike that would support it. It's a pretty awkward bike to try and get a flat surface.

    Yeah I couldn't believe it either. When I spoke to wreckers as well I thought they would be cheaper too. I even said just would supply the forks of the bike with the seals!! Robbers!it's like an hour's job with the right tools...
