    Default building up a honda z50 engine

    hey guys i just scored an oldschool z50 and wanna rebuild the tired old engine.

    plans are to keep it as quite as possible but get as much power out of it as possible and have a nice revy engine.
    i was thinking the following;
    75cc or 88cc bore kit
    high revving cam
    stiffer valve springs
    and a bigger carby

    what do you guys think?
    please add anything you think would help.

    btw its just a little side project so i dont wanna blow too much money on it.

    Na I don't. I'm gonna go see this guy about it. Apparently he has a few of them. Should be able to confirm if it's a complied model and maybe sell me some parts

    The guys at Horizon motorcycles in Glenorchy race these things for a laugh, I know a couple of them have done big bore kits, cams etc. Might be worth contacting them if you get stuck.

    I would be happy to help you adapting a different engine in for a modest rate. Would be funny as if I ported one of those heads, would probably be the smallest thing I ever get to do
