I would not do all that for a K6 rim.  Just save the two hole hub in case you find a nice K0 DID rim without all the stampings, or by some miracle find a decent rolled rim.  That's my two cents.

Good advice

Got a K0 rim in your batcave?

Here's my k6 rim with good tire.  I'll swap right in when I get your center stand

Those were the best carbs ever made for this bike!!
They are worth $600 alone.
Very easy to work on.
The most power.
They can be used on ANY CB750.

Last test would be to pull the countershaft sprocket cover and look for some chain damage on the case but with those miles sounds like you are probably good. Get rid of that possible stock chain though QUICKLEY if you start driving it    ;)

I agree completely.

What is it about the early carbs that is more desireable ?     I was under the impression that the carb bodies were all the same casting at least for the 69-76 models

Which carb is the earliest ?   657A, 657B or 086A     Sorry to thread jack.   GREAT FIND - GREAT BIKE.
Yep, I'm the kid that figured out how to put things back together...eventually.

K0 DID rim without all the stampings, or by some miracle find a decent rolled rim. 

What are the differences? I've been looking for quite awhile through some posts and pics, but just can't tell the differences.

It's hard to see in pictures.  The rolled rims are very round at the shoulder, and looks rolled to where it meets the tire.  The other markings I referred to were the size stampings on most of the rims you see.  My K0 rim only has a single DID logo between two spoke holes.

Greggo - Were the rolled rims on some K1's too? I have a front rim in the batcave that looks different than others I have.

Just bought this, taking delivery next week.  I hope it's a K0 rim if rolled rim is wishfully thinking?

I'm very sure it's not a rolled rim, but if that DID stamp is the only marking it's correct for a K0.

I didn't think so either, but I'm no Sandy expert. The rim I have looks very different [besides being a front].

The early front wheel front is not as round edged as a rear rolled rim is. Not sure why. Maybe the 19" front wheel tooling was newer than the 18" rear wheel tooling.
 I had to buy the PO's drag bike to get the original rear rim for my sandcast. Oh Darn.

 I think a good replacement rim is more acceptable on a diecast than on a Sandy.

I just wish it was, but I could see third hole in the shadow.

 I was told the 2 hole hub sells well, No one can see it installed not many guys care. I saved one by relacing the harley wheel from my drag bike to a 4 hole hub, it seems it wasn't worth the effort. I'd sell it or trade for something interesting.

Nice guages..
 Does it have the 16/45 sprockets?

Front is 17, rear must be something other than 45? Can't find marking in it

It's been quite awhile, just got a chance to pull the rear wheel off the bike, going to clean up the 16 incher and see if it can be put on another project....low and behold, 2-holes rear hub with different style cush drive rubber, and 45 rear sprocket.

Definition of Sandcast:

A piece of aluminum that was manufactured by Honda in the late 1960's that eBay sellers think it's value is comparable to gold!
