wow! don't even think about it! the zx9 and zx7 not only have a different bore, but importantly a different stroke, which means that you cannot share the cranks! DO NOT even think about this! theres too much that WOULD (not could) go wrong here! i can't even imagine! find an b-series motor or good crankshaft, but only form a 1994-1997 ZX-9R. good luck!!!
