I did my 74 k5 a year ago powder coating the whole deal came out great. If you have not sugggest you replace the oem rectifier with a radio shack full wave rectifier better charging and your battery will hold a charge longer. Cost less than 5 bucks. get rid of the lead acid battery and replace with a Werker 6vlt 5amp hr glass matt battery. No more acid on the bike eating the paint and everything else up. Its available from batteries plus on line. These are great fun bikes on road and off top end 50 to 55mph and in the low range very capable of handling the steeps.
