  1. it's been a while but i thought incase anyone has the same issue i'd write the conclusion to the story.

    I finally bit the bullet and took it into my trusted Aprilia/Suzuki/Moto Guzzi/KTM/Seadoo/Spider shop and they got it going, electricals all good, just cleaned the injectors and a fresh tank of fuel and it's running again, i'll get them to do the valve clearances while it's there. Having a celebratory beer now, so happy to have it going again.

    I was reluctant to take it to a shop, a guy at work told me of a blackbird with similar issues and the shop took 30 hours to diagnose the problem. But after they found the obscure problem with my Aprilia in a morning i thought i should give them a go.

    So not sure if my replacing spark plugs, fuel filter and fpr contributed to the solution or not.

    Thanks everyone for your suggestions and support they are much appreciated.

  2. i was just thinking the same thing, brembo rcs master would be nice, just have to find out the piston size on the stock one.

    Best bang for buck though i would think for improving braking power would be new discs and xrac ferodo pads, my duc went from being worse than the bb to way better with this.

  3. I thought i'd replace the plugs anyway, it's been a while since the major service and pretty sure they weren't changed then.

    Looks like I've got a problem with the battery now, I cranked for quite a while last time I tried to start it and now it's down to 11.7 volts roughly, so i'll put it on the charge and replace the plugs and see how I go.

    I didn't think it was related but now i'm starting to wonder, the last time it was running, I hit the starter with it in gear and the clutch not pulled and I think I blew the headlight. I started it after that but only ran it for a few seconds and put it away until I got the headlight bulb replaced, since then it's played up.

  4. thanks for the input guys.

    finally got a chance to try the bb today.

    12.8 something volts before attempt, gas cap closed, hit the starter, cranked for a long time, really fast but nothing, checked voltage after cranking, 12.3 something, opened cap, volts back up to 12.7 something after a minite or so, cranked again really fast but still no fire. Volts after cranking 12.4.

  5. Put it back together, pressured up the fuel pump, and it started in the garage straight away, sounded a little rough but I thought it might be ok, switched it off before I suffocated, wheeled it out, it fired up straight away, went to 1500 or so, but then started to miss, I grabbed the throttle as the revs were dropping, got it up to 2000 and it seemed ok for a few seconds then started to die again, picked it up to 2500, ok for second but then the revs started dropping again so I let it die.

    Brought it back inside and primed the fuel pump again, pulled the vacuum hose dry as a bone.

    Checked voltage before and after each cranking over, solid 12.95 volts, (shorai lithium bat) plenty of cranking power there too. Couldn't really check the voltage while it was running.

    So I guess plugs next, wouldn't hurt anyway if they're still the originals.

  6. the day after filling the tank, of course, I went to start it and it started ok and ran for a few seconds then dropped to maybe 1 or 2 cylinders then stopped altogether. In the last 12 months it's spluttered occasionally so I've been running injector cleaner through it. So when it died completely I was hoping it was just the fuel filter blocked, pulled the filter and it seems to flow fine. Everything looks fine, no loose wires or fuel leaks, recently I've replaced the air filter and low beam headlight bulb but I can't imagine that i've caused any issues doing that. There is a breather hose not connected to anything but I can't find anything it would have been connected to.

    the thinner hose in the bottom of the pic.
