Original CB750 Manual, 1970

[MrDavo]

I was lucky enough to buy this on eBay, for a £30 offer. Its an original March 1970 manual, I know its all scanned and available in Ash's dropbox, but there's nothing like having the real paper article for browsing, checking and to go with my orginal partsbook.

Somewhat used, but not with all the dirty fingermarks that fill most of mine. I must try and take care of it.

The bike in the photos is chassis #2, engine #4. Does that make it one of the prototype show bikes, if so which one?









Therer are neatly handwritten service notes in the back, for a bike dated April to July 1971, at 4,947 miles, I'll try and take a photo tomorrow.

Got to agree I find a proper paper book alot better and easier to browse ...and always waste money buying  them to go with whatever bike I have....well not so much waste but it's a cost I know I don't need to incur ...but always seem too do...
Buy saying that the online references are fantastic too..
And in saying that... the first stop for any of my fours is this site..
Time to donate me thinks

Nice find .. Yes you can't beat an original copy of the manual Dave. I have them for a few of my bikes and the Parts Books in particular are a godsend.

Someone on here will know, don't make me have to go and look it up.

Best thing is ask the question on the sandcastonly site Dave.. Or I can ask Chris Rushton on Sunday at Newark for you ...he's bound to know.

BTW I have the 4/69 Sandcast parts manual in .PDF but I don't have it in the Dropbox links  for 'general release' . However, if you or anyone else who needs it wants it, just PM me for the link.  It is far better than the later K0 parts book as it has more details on parts, particularly on the  carb internals etc. All I ask is,  if you do get me to link it,  is not to publish it on the net . It was like getting blood from a stone getting anyone to agree to scan it for me, as they wanted $$$$ for a hard copy but a guy in the States kindly did it for me .

I just checked the pictures I downloaded of Vic World's blue prototype when it was eBay, that has weird numbers, CB750-2113 on frame and engine, so the bike in the manual must have been one of the first production bikes rather than one of the prototype show bikes.

Please send me a link to the parts book, Ash, I can never have too much info, My parts book covers K0 - K2. I promise not to release it into the wild.

Would a prototype bike have a correct vin number..for model
Surely only production bikes would run with vin numbers as they would start with 00001 when put into production
Does that make any sense

From Vic World who sold that pre-prod bike and is the sandcast master Guru 

"Hi, Thanks. This Frame is CB750-2113, with engine CB750E-2113 It was common for Honda GP race bikes and prototypes of the 1960s to have the same numbers. The very first prototype CB750 (a few months earlier than my bike) which was shown at the 1968 Tokyo Motor Show had Frame/Engine numbers CB750-1101. The first "1" means "first series" produced of the proto, the next numbers (10) means nothing, and the last number (1) means first bike made of that first series. That bike never left Japan, and nobody has seen it since. The second series (the 4 bikes that came over together for the Las Vegas Show) were numbered........ 2110 (Gold Bike)....... 2111 -?color (Red or Dk. Green)........ 2112 -? color (Dk. Green or Red)..... 2113 (my Blue/Green Bike).......... The first number (2) means "second series" of protos, the next 2 numbers means nothing, and the last number (0,1,2,or 3) is the sequential number assigned to that color bike. (Actually, the 3rd number in each of the 2 series is a check number, but you get what I mean). Thanks again, Vic"

Wonder how he knows some of the numbers "means nothing?"

I bought a hard back ex library book version of this manual of ebay in perfect condition a few years ago - I use latex gloves when I use it to keep it in good nick!

Nice slideshow here Dave on the pp prototype

I see 2113 sold for $148k in 2014 I think about £90k at that time.
See in the BMF magazine that the third prototype Vespa scooter just sold for £158k. (Over $200k ATM).
All very well about "maximum worldwide exposure" but he'd have been better going through a specialist auction room.

[MrDavo]

The slideshow was good, all the pictures I have I saved from the Vic World eBay listing, many show internals such as the billet crank.

Ohther than the one stashed away in bits that Ash knows about, 2113 has to be one of the most important bikes there is.
