    Just which rod it started as eg Atc110, which i thought had a 30mm pin
    I can always change piston top to suit or different length rod or gudgeon etc .

    The early points 110 had a 26mm pin. Same centre to centre length as the 30mm version.

    Thanks
    Good news
    One of those rods plus a xl piston and a 125 barrel would get everything lined back up
    Crank lasted 25000km little end let go

    Most strokers used a "stock" rod that was modified as Kasey mentioned. You should be able to find one fairly easy and cheap on ebay.

    Looks to be a standard H&S 58mm stroked crank with squashed rod which eliminated the need for cyclinder stroker plate. Early strokers used stock rod lengths and stroker plates, longer cam chains and a couple other modifications. When you do build it, post up a thread with pic's we all love to see custom projects.

    I built this motor a couple years ago. I used the above crank and atc125m barrel decked down 6.3mm and 57mm gy6 piston.

    Looked back at your attached thread, see I posted in it asking about the unique use of hole saw to bore cases. Too bad the pic's are gone, as I remember they showed the many process steps performed. Did you complete the other project?
