I sprained an ankle on my 1951 before someone stole it, bought a 1962 had it until I got my electric start in 1966 and never looked back. as of now I have never sprained a thumb pushing that little button on the right handlebar. in case you are wondering no I do not have the 66 any more traded it in on a 67 the oldest bike that I have now is a 1986 and that as you know is not a vintage bike. All of my equipment lawn mowers Etc are electric start or totally electric. YES I AM LAZY but I do appreciate the effort you guys put into the vintage equipment I do attend steam shows with my 1946 electric start John Deere A . OK I do not want to occupy any more of your time as I know you are on a short time schedule. Best Regards See you in EUSTIS.
