hello all i have recently purchased a gpz 1000rx and after two rides the engine has cooked. i live in australia and can find no easy to get parts for the bike, hense the reason i wish to fit a late model zx 10 engine to it. i was wondering if any one could help with technical info on the bikes. i have been told that the engines from 1985 till 1990 have only changed slightly and that it should bolt in. any help would be greatly welcomed.thx chris
