Just got a project in bits , Z1000 a2a 1978 however it had a late 70's workover and i am debating whether to do it up as is or standard .
to go standard main things i need are a pair of wire wheels and a complete airbox and rubbers . the later being i fear unobtainium !
anyone got eoither of these ? there will be loads of other small parts but these 2 are the hard ones i think
Thanks
Mike

I have a set of wire wheels removed from my z1000a2 also original grab rail with the indicator lugs.no discs or spacers.
No idea the value.can send pics if interested.based in n.ireland
