Hello everyone I need suggestions please, here is an Update on the bike, its a honda z50RD 1986 Christmas special all chromed. I Removed the tank, seat and fenders. Seat pan is damaged, i need a seat. I Will be treating the inside with evaporust, now on the petcock, the treads for the petcock are damaged, any alternative ways to mount the petcock? Or repair? Not ready to spend 2k on a tank. Last, im going to continue taking the bike apart, frame is very solid and very light rust on it but the chrome needs to be bought back to life, whats the best technique and safest harmless chrome cleaner i can use?
