    Success.... slipped the Starter out this morning and had a look inside. It was pretty sad to be honest.
    So I ripped the one off the matching Numbers motor, wriggled it into position (without disturbing the starter gear so no generator cover removal) and bingo... she winds over like a trooper.
    Spun her up for a bit until I could see oil in the cam bearing caps. I then removed the new loom and I am soaking most of the connections in Cleaning Vinegar to make sure all connections are clean and corrosion free... As it was alread 32 in the shed I have now retreated to the house... rearranging my Office with the cooler running, at least till the Cricket starts lol.

    Mine should get a bit better power than that.. being a 350 with the Factory high lift cams etc... not that it makes a great deal of difference.

    Hi Andy
    Sorry for the slow reply for the pictures of the 350 quad starter motor , it's mounted differently than our SRX's though.

    Cheers mate, having pulled the original one apart the 3WP and the 51Y are different inside. I might secure a 3WP one from Japan as the brush plate etc is available for them.

    Morning Andy.
    WOW , and here's me thinking the 3WP and the 51Y are basically the same.
    The brush set off the 3WP starter motor , will they fit the 51Y brush holder's ?.

    No, If you look on Megazip they are completely different. The 3WP starter uses the same brush holder (includes the brushes by the look of it) as the FZR 400.

    HI mate, yes that is the one that suits the 3WP starter but not the 51Y starter... it is different I will take some pics of the internals of the 51Y in the next day or so. I only have the 51Y starter and it was very dry inside, brushes almost worn right down and the sleeve bearing on the back end was dry as well.
    They look to be a cow of a thing to reassemble too.
