Here is a used Chain Guard from a 1985 Honda VF500 V-30 Magna Motorcycle.  This Chain Guard is used and shows it.  This is solid and straight, but does have pitting and marks of wear.  Not pretty at all, but maybe better than the one you have.  It mounts on solid.  This is 34 years old.  Please look the large pictures over good.  You'll receive exactly what is pictured.  This MIGHT fit the 1984 V30 Magna, maybe 1982 1983 1984 1985 1986 V-45 Magna 700 750.  

                                             PLEASE, check with your local dealer to be sure it fits your other Model Honda Cycle.
