Title: Honda CB750 (Jan 1970)
Post by: jojotut on June 11, 2014, 11:34:30 AM
Hi everyone, trying to piece together the proper specification for the above bike. I have read quite a bit of information but would like to pick all your brains on the spec this bike left the factory before I start pulling it apart again.
Colour, although the tank is gold I don’t think that this colour came out before frame number ###20000, mine is around the ###19000 mark.
Tank, should it be a wrinkle tank?
Front mudguard, should it be single or double cut?
Seat, should it be ducktail?
Can anyone give me the correct spec for this bike I know they changed them very rapidly over this period.
Every bit of info would help.

Hi no I bought it a few years back from an importer, I have been buying original nuts and bolts from Germany, got some new forks and wireing harness from the States. Its a US spec bike.
Its complete and runs all chrome is good, but I think the front mudguard is a later one.
Should it have a black kill switch (forgot to ad this one to the list)
Exhausts are repairable but not `300`. I will replace these with pattern ones (Anyone know where the best place I can get some from).
Thanks
JOJO

Think Gold was available at the end of '69 (there was a pic of one on the US site) and of course one of the 'Brighton Show bikes' was gold/white. Also seen a couple asian market gold ones that GI's brough back after Vietnam. Two colours available originally were Candy Ruby Red and Candy Blue Green. A person  on US site from Toronto posted a pic of a sandcast bike he bought in summer '69 Gold/white stripe tank.
Definitely should have ducktail seat.
Almost certain double cut fender at front (mudguard) with no cable grommet thingy.
Hmmm on wrinkle tank . My 10/69 UK K0, I am pretty certain, did not have one originally. But hey-ho everyone seems to disagree.
I think it should have 'antimon' alloy fuel cap too and no black stripe on bottom seam fuel tank trim.,
Black Kill switch for definite & recessed ignition switch.
Narrow front hub / two hole rear hub.
Louvred side panels.
Short style plastic chainguard (may have been swapped as recall though).
Oh and that tw*t of a rolled rear DID
rim that I can't get hold of.

Silvers for exhausts as they are  Yamiya  (or were) and you save yourself import/shipping duty .. but check as he is having HM341's made in Italy now. Yamiya ones definitely good quality I believe.

Shoot me down if anything is wrong !!

Thanks for this info lads its very helpful.
On the pipes thought these should be MH300, still cant afford them.
Nice info on the wheels will take a look, I will post pictures (hope you wont laugh).
Should carbs be 4 cables into one, mine does.

Carbs definitely 4 cables into 1, apart from transition 'K0' model in late 1970.
Don't worry about pic,  Any K0 is worth restoring. (as long as you have deep pockets  ;)).  And drives you nuts trying to locate the correct parts.

Cheers .. AshD
