This site is a result of the investigations I have done while restoring a number of LC's. I originally collected the information on this site for my own use but due to all the help and assistance I have had from so many fellow LC enthusiasts I decided I would make it accessible to anyone attempting to restore there bike to original condition.

While I have made every effort to find a definitive answer to the long running question "what is standard" I have come to the conclusion that there is no such thing. You should remember that when originally built they were built to a price and not a standard hence suppliers would change along with the finish of the parts they supplied to Yamaha during the bikes production run.
