I'm looking into doing a future project with a KZ650 and wanted to try to get some info before I decide what I'm doing. It looks like I'll probably be getting a 1977-78 KZ650. My question is, if the bike I get has Mag wheels, is it a direct swap to replace them with spoke wheels from there same year KZ650s. Also if it is possible, if I swap the rim size what is the widest front and rear tire that would fit without rubbing. Thanks for any info.
