CB750 / K1 carb question
« on: May 13, 2019, 08:50:44 PM »
Hi all,
I'm bracing myself to start dismantling my carburettors, I'm just checking them over , taking pics and working out which bits to zinc plate which to chrome etc before taking the plunge. Are the bowls and caps polished or zinc plated ?  I've also noticed what appears to be a screw where there should be a bolt on the plate set (stay) highlighted in the pic hopefully. Is this correct or has someone been losing bits? Finally any tips before i take the plunge? Thanks in advance!!

Yep, welcome. I'm glad I'm not the only one can post upside down pics ! 😂😂

It seemed to be the right way up. How do you tell?   ;D

Yes it looks ok when posting it and it's the right way up when enlarged. I can do the same trick when I'm using my iPad to take pictures...... seems I was using it upside down! 🙄😂😂

I would not say that it is being a anorak, it is just knowing the history of your bike.
The K1 was fitted with two different types of crank cases fitted. The early K1's had the crank cases used from the K0's  ( with slight changes in the castings ) and moved on to the later cases, which were used on some of the K2's.
The engine evolved over the years with 3 different types of oil pumps, 3 different clutch baskets, 2 different selector drums and so on. I don't need to see a engine numbers to know what year it is  :o Or if it has the wrong barrels or head fitted for that year. I have never found anyone that has wrote a book on all the correct detailing of the CB750K engines.

You can't beat knowledge gained by actually working on these engines over a lifetime....or practical experience in any job...and a good job for us that you and others are willing to share it! 👍

Nice one..just noticed on your lower case, the large round section has a securing clamp on it which mine doesn't have. It has the post for the bolt but it is undrilled. I assume some have it and others don't ?

That's because it is a it is a early K1 and yours is later  ;) Yours also has M6 flanged engine bolts and the one i am doing is the non flanged type. The oil bungs on the early's have a 17 AF and all later units were fitted with 14 AF.
Cheers Trigger...I must be turning into some sort of anorak! ...I find all these little differences/changes quite fascinating!  😬
