Hi All,\n\nI have a mate with an 81 750 Katana with a crack in the crank. The\nbike is currently in bits and I'm going to help him put it back\ntogether over the next few months.\n\nSo does anyone know of anyone who can either weld/grind/balance the\ncrank (in Melb) or has a working 750 engine for sale? (or a complete\nbike, depending on condition/price)\n\nAlternatively, does anyone know if any other engines will fit in a 750\nframe (eg. 1100 kat motor or gsxr 750/1100 from the 80's). This is a\nlast resort option as my mate would like to keep it standard.\n\nThanks in advance guys.
