Hi, new to the zb world, but already in love with the little thing. I just got a 620 mile, untouched, original (i think) zb50. Original tires and all. Problems: Missing mirrors. Is there another honda with similar ones that are easy to get? Also, this machine has been parked for 15 years. I have the gas tank pretty well cleaned, but there are some sections of the tank I feel still have a lot of varnish (probably unseen). Is there a magic solution i can put in the tank and have it look like new? Its not really rusted, just like dried gas. Thanks for the help.
