Download i don't know but i have all the genuine Honda dealer workshop manuals and a lot of the parts books, including UK F1, all on one dvd that you can purchase a copy of for a reasonable amount of beer voouchers! PM me if you are interested with an address and i will work out a postage cost.
Honda manuals by the way start with the original 1969 cb 750 and then they issue supplements of differences for every new model till the F2 when a completely new book came out
