What are the speed blocks? My first bike when I was 16 in 1973 was a 1972 'L' reg FS1-E in the original Candy Gold colour (actually a SS, before they changed the name to FS1-E due to a legal name case with Honda regarding their SS 50 model). It had the pedals that were usually set as footpegs. I tried pedaling it to a petrol station once when it ran out of petrol, but ended up getting off it & pushing it as it was easier. It would just about do 50 mph, with a tail wind. I paid £110 for it, second hand & I wish I still had it as they are now worth between £5,000 & £6,000. Mind you, my wages were only £14 per week back then.
