    Default Lazy starter motor

    Hi all. My Africa twin rd04 has a lazy starter. When you first turn the ignition on it behaves like the battery is flat. Nothing. Then you try to start it again and it sounds like it's trying. Then you try again and it turns over a bit but won't catch. Then again etc until it turns over fine and eventually starts. Battery is clearly fine and holding charge. Any ideas? Tia

    I'd try jumping it off another vehicle to be sure, if you haven't already. Batteries can be funny things.

    Starter solenoid past it's best. Well, it should have been pensioned off by now.

    And check the earth connections for corrosion, particularly the big connections to the starter motor - electrons are frightened of rust and won't go anywhere near it.

    I think connections are ok but will check. Solonoids seem to be fairly standard. Or does it need to be model and make specific?

    Could be a bad cell in the battery. You'd get volts but not amps.
    Could be time to service the starter. Just open it up, blown or brush out the dust, and check there's some brush left.

    Battery is fairly new so hopefully not that. Never had a starter off to clean etc. Easy job?

    Could be a number of things, I had a GSX750 that behaved a bit like that and the problem turned out to be a couple of failed big end bearings, though I very much doubt if this is your problem.

    Prime culprit has to be the battery, replace it, they're not expensive and easy to change, charge the new one before fitting.

    Starter solenoid is unlikely, they usually either work or not, easy to test, just short out the two big terminals with something fairly thick, the starter motor should spin like your pressing the button.

    Starter motor is a possible, starter clutch is more likely, but could be a tight engine.

    If it was mine I'd replace the battery and then see how it was.

    The starter solenoid is not model specific. According to CMSNL, this particular part fits 1452 models. Part number: 35851MF5751



    Later models have a different shaped unit which is a rectangular block rather than this "round" one.

    It's only a solenoid. As used on almost every vehicle since time began. My old z550 wore a 'mini' solenoid I bought from the local motor factors - the only issue is making it fit neatly in the allotted space.

    As for the starter motor, twat it with big hammer.

    Usually two bolts holding the parts together, take them out, split it, and clean.
    Careful with the end plate as there are springs in there but not too hard to keep together.
    There will be an O ring so it may resist pulling apart a little
