Can't see if you have the roll pin fitted and are all the half rings in ?

Have you done a dry run, to make sure all gears select .

Yeah looks really nice... its better if you can split the cases for painting. Mine was painted without splitting, as the motor internals seemed ok so a shame to split, but the painting looks betterr on yours.

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!  😬

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.

Books Paul, i can't even be bothered to read one, never mind write one. Never seem to have time with members asking questions and looking for parts all day  ;D ;D ;D
