    As a few of you will already be aware, been having issues with Kerry. Keeps losing the spark and the only conclusion I can come to is a faulty stator/pickup.
    So bought a new one and flywheel only to find they sent me the wrong one, twice, and now I'm really struggling to find a new replacement.
    Now, my train of thought is this. If I'm struggling to find this part, new, not an ebay jobbie, how is any other potential owner going to get on?
    So, although I will keep battling on with this, I'm thinking it might be better to change the engine completely for a more part friendly one.
    Anyone have any conclusive info as to what would fit without too much hassle?

    Surely it's a Minerelli engine so any minerelli engined scooter stator should fit?

    Its the suzuki engine. Morini. All the stators I can find have a 48mm bolt hole centres, this one has 40mm centres.

    could try shouting at it? have you tried that? i bet you havent tried that (he hasnt tried that)
    shouting works....
    im all out of serious ideas now.
    also could it potentially be the ignition switch, sometimes the "fuzz up" over time, you know the moving copper bit? try just bypassing it to rule it out 100%

    No, no room, looked at that, and an adapter plate but flywheel wouldn't fit after.

    nrg has the aircooled piaggio motor, but maybe there are some with the morini lump (early models maybe?)

    The Mojito is actually called the Habanero in some markets e.g. the US), so you are both right. The Mojito does indeed have the Morini engine.

    Well then, 5 1/2 months down the line and I found the problem with the lost spark:D
    I've had the last 2 weeks off so have just been able to get around to it.
    Turned out the wire from the pick-up had a break in it that only broke sometimes. Hence the lost spark.
    Wire replaced and nice strong spark.
    It still has an issue with not idling nicely, I've been playing with that all day. But it picks up nicely and pulls off very well, as long as you keep the tick-over higher than normal, which I'm not happy about...........
    I also fried the cdi in-advertantly, so had to replace that.
    But after sorting out the spark issue, and getting the jetting near normal,took it out for a little spin and..........................I've only gone and blown the friggin' piston innit!!!!!
    Damn thing bellied up and sucked wind. Rolled onto the drive and into the garage, done a compression test, 70psi.
    To say that I am now utterly pissed off with this is an understatement.
    I have another top end on the shelf, I think I'll stick it on, get it running again, and then e-bay the fucker.
    I'm done with it.
    I know I'm going to loose a bit of money on it with all the stuff I've done, but I no longer care.
