building up a honda z50 engine

[Nic19]

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.

I would be happy to port it for you if thats any help to you

so do you have a workshop manual for it?

[Nic19]

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.

Nick ill tell you if its a complied model or not.

Put a CT110 engine in. Should come close to bolting up.

[Nic19]

Well get out here and tell me! I need to did a place that make repo parts.

[Sam-Q]

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

[Nic19]

Thanks sam but I would rather not pay for work I can do. I have a crf50 with a 125 in it already.

that's the spirit! keep us updated on the progress ok?
