honda z50s' 1976 honda z50

[honda z50]

i have a honda z50 and i am rebuilding the engine to a 70cc and i was wondering does anyone know what size jets i should be using,
and i was also after the valve cover things that go on the engine, as my old ones are rounded

Why 70cc ? why not just drop a 88cc tb or takegawa kit on it like most people 70cc wont be much of a improvement for the dollar outlay involved.

If you really want to go 70cc why not go 72cc and use bore, piston, head and carbi from a CT70 motor ?

and do you know were i could get the valve covers from
